“A picture is worth a thousand words,” says Robert Pelton, with the Altamonte Springs Police Department, whose crime scene pictures now come in 3D!
Traditional scene analysis is a lengthy process, requiring hundreds of pictures, measurements and sketches. The new 3D scanners, made by FARO, can capture the entire scene in a fraction of the time.
Orlando Florida’s NBC news affiliate, WESH Channel 2, aired a story on the 12.02.2015 at 6 p.m. EST featuring our FARO X330 laser scanner and FARO Freestyle3D. The segment was titled “Local police using 3D Crime Scene Technology” and is to promote new technology that is helping law enforcement personnel solve crimes. To see the story, click the link above.
The Sessa Aurunca Cathedral is therefore a building of superb beauty dating back almost one thousand years, with an absolutely unique feature: it is “the other original”, an almost exact copy of the church at Montecassino which, as is well known, was destroyed by bombing during World War II and subsequently rebuilt. The two buildings differ only in the number of naves: Montecassino has five, while Sessa Aurunca has three. The Sessa Aurunca Cathedral is one of the infinite “pearls” of Italian artistic heritage. Indeed, it stands out for its beauty and historical significance: despite the changes made over the centuries (Baroque and eighteenth-century additions), the cathedral still bears direct witness to the typical religious architecture of the period, combining structural rigour, Christian symbolism and a number of refined Byzantine-style elements (such as the splendid mosaic floor).
Despite its obvious significance, the Sessa Aurunca Cathedral is not well-known among the general public and is overlooked by “traditional” tourist flows. For this reason, the diocese and the municipality of Sessa Aurunca in the Campania region of Italy decided to launch the “Sessa Aurunca 3D Project”, a communications project designed to promote the Cathedral and provide the associated services and products.
The “Sessa Aurunca 3D Project” has several goals and is broken down into seven specific points that will explore new frontiers within the world of communications: the publication of academic and scientific reports and articles; the organisation of conventions, seminars and events; the production of stereoscopic 3D animations and videos, with the creation of a You- Tube channel and dedicated videos; the creation of a “360-degree Virtual Tour” with a database and “multidata” to “explore” the Cathedral using computers and mobile devices; the creation of thematic apps and a website; and the production of a “docu-film” about the project and the technologies used. Regarding this last aspect, Danilo Prosperi observed: “Part of the success of this initiative can be attributed to the FARO Focus3D Laser Scanner, an extremely precise device that we used to scan the Cathedral’s architecture, which provided us with a point cloud or, more precisely, digital data that we were able to use in our various activities.” The data acquisition phase involved 38 scans made inside and outside the church, including the crypt, and took just over half a day. “The quality of the FARO Focus3D Laser Scanner enabled us to acquire extremely high-resolution and high-precision images with very low margins of error, which was fundamental for the scanning of extremely beautiful details, such as the mosaic floor, the ambo, the spiral Paschal candelabrum and the crypt on the lower level.”
The data gathered was then processed in SCENE, the FARO software for the management of scanned data, designed specifically for the Focus3D. This software was used to create and edit videos and images for the 3D Virtual Tours of the Cathedral. “SCENE,” Danilo Prosperi specified, “allows us to easily process the scanned data and quickly generate particularly complex high-resolution equirectangular panoramic images”. Danilo Prosperi stressed: “We believe that the FARO Focus3D Laser Scanner is the best technology on the market, not only due to its extreme precision, but also because it is so flexible, fast and easy to use. In fact, it is a compact instrument that is very lightweight and easy to move from one scanning position to another.” He concluded: “The collaboration between FARO and the Master’s in Architecture, Sacred Art and Liturgy at the European University of Rome has only just begun. Given the quality of the results, we plan to use the FARO Focus3D Laser Scanner in the future for other projects aimed at promoting highly important monumental sites of great beauty.”

It is no secret that where large-scale major investment is concerned in the current economic climate, infrastructure is a serious front-runner. As one component of a multi-pronged assault on rectifying the UK’s extensive debt crisis, Cameron’s government has pledged billions to the preservation and vast improvement of the country’s arterial infrastructure systems in the hope of stimulating a kick-start for the country’s long-term economic growth. With high-profile projects such as HS2 and Crossrail at the vanguard of the £36billion major infrastructure investment plan, the subject of national infrastructure has become one of 2014’s hot topics. Opti-cal caught up with Ted Harland of Tri-tech Site Engineering and Land Surveys in a bid to get the inside scoop on one of this year’s largest projects; the high profile £300million upgrade of the A1 between Barton and Leeming, that upon completion will see journey times in the area cut by as much as twenty percent.
Tri-tech themselves are a Yorkshire-based surveying and site engineering company, who since 2005 have gained a solid reputation in supporting and facilitating project success for both public and private sector clients
“The project is essentially a £300m upgrade of the existing A1 dual carriageway to 3 Lane Motorway”, explains Harland, MD of Tri-tech, “upon completion, the project will also provide a number of local access roads to serve the local community, and significantly improve safety in the area [which at present lacks the local access roads necessary to accommodate the area’s numerous agricultural vehicles.]”
Falling beneath the broad umbrella of major infrastructure projects for 2014/15, the A upgrade sets the tone for contemporary project process in its use of 3D Laser Scanning Technology, as well as the firm insight into futureproofing the venture’s work through BIM (Building Information Modelling) workflows. “There has been a big push nationwide to start to deliver projects through BIM”, says Ted; “This in turn with the recent development of Scanners, PC Software, and PC Hardware has meant that now more than ever 3D laser Scanning has become a viable option for data collection for this kind of project.” “We have used Opti-cal for number of years now for the supply and service of all our equipment …Their support and service is second to none”
“We were asked by the Morgan-Sindall Carillion Joint Venture (MSCJV) project team to survey a number of existing bridges for the structural design team to process”, he explains, “some of the existing bridges are to be kept, as well as a number modified to suit a new 3 lane Motorway. After having various discussions with the design team about their specific requirements, and whether they could handle such large amounts of scan data, Tri-tech choose the FARO Focus3D X330 model for the job largely because it is the ability to scan at a far.
” Since its arrival on the market last year, the FARO Focus3D Laser Scanner from global manufacturing powerhouse FARO has evolved in tandem with the changing requirements of the survey teams using it. In November last year, the original S120 model was replaced by the first of the X series units – the X330 – which boasted considerable range whilst maintaining the compact 5kg housing that has gained this particular brand of scanner well deserved industry-wide recognition. “In the past we have used the Focus3D S120 to scan a number of buildings for a client”, he says, “The results were excellent, however on this project we knew we required the additional range of the X330 to confidently scan the structures from both sides of the carriageway and get good results. Because we only have access to the side of the motorway sometimes the distances needed to be scanned would have been right at the limit of the S120, which is why we went for X330. In terms of the hire itself, we have used Opti-cal for number of years now and so it was natural progression for them to supply the scanner and all accessories. Their support and service is second to none.”
Speaking about the data captured at the site, Peter Robinson of AECOM’s specialist design team said, “The use of the X330 FARO scanner by Ted Harland of Tri-tech has provided the A1 Dishforth to Barton structures design team with invaluable information. The [sheer] level of detail obtained from the surveys has left a number of the design team speechless, and has allowed [the highly] accurate modelling of existing structures.” He continues; “thanks to the coordinated point cloud obtained from the surveys conducted, we discovered that the original surveys carried out [at the site] were in fact inaccurate, which could easily have led to costly issues on site.”
Here, Robinson highlights the very issue that awards Laser scanning its rightful place at the heart of much of the industry’s recent lean towards Level 2 maturity BIM workflows; that the data you get out of a model will only ever be as good as the data you put in. And where Tri-tech is concerned, no expense has been spared in ensuring total accuracy for MSCJV and the holistic success of their project. “There was quite a lot of prep work prior to the scanner arriving on site,” Ted continues, “control had to be established at each structure using GPS and then tightened up using a total station; all stations were then digitally levelled to tie them into the site network. The beauty about scanning and scan data is that you capture everything in one visit – which at the end of the day saves the project both time and money.”
“We managed to scan all the structures in 4 days with a total of over 40 scans taken”, says Harland. “The processing was then done the following week using the Faro Scene, and the data exported out of FARO Scene Software in a format ready to be imported into Autodesk Revit/Autocad. We know this data is of an exceptionally high quality, and can now be used to design and model all new additions or changes to the motorway bridges – it also provides a real snap shot of what is there now as a record forever, in true 3D.”
With work commencing in March this year, the venture is by no means a small undertaking; “The project is due to be completed in mid-2017,” says Ted, “and I am confident that should there be any further survey work of bridges or structures, laser scanning will certainly be a first choice – not only by the designers but by the site team too.”
An essential part of modern 3D Documentation is, of course, Mobile Mapping. A mobile mapping system is the integration of remote sensors and time synchronised navigation. It is an extremely powerful tool for large scale 3D information collection e.g. road mapping or 3D city models.
With mobile mapping systems costing up to £1,000,000, a FARO Focus Laser scanner can be easily converted into a mobile mapping system with minimal investment. saving you time and money.
‘DIY’ Mobile Mapping
‘DIY’ Mobile Mapping can add a huge amount of extra value to the FARO Focus 3D. This enables the user to gather 3D data in a large scale and to work very efficiently in an outdoor environment. In addition, the FARO Focus is not attached to the mobile mapping system permanently and so it can still be easily used as a regular laser scanner at any time.

Affectionately known as “The Hammers” and now in their 9th year, the Construction Computing Awards showcase and reward the technology, tools and solutions for the effective design, construction, maintenance and modification of commercial buildings, residential and social housing and civil engineering projects of all sizes.
Among this years winners was the FARO Focus x330 3D Laser Scanner, which was able to prevail in the hardware product of the year category of the renowned Construction Computing award contest!
The Focus3D impressed due to its extremely powerful and accurate three-dimensional measurement method, which offers numerous advantages compared with conventional measurement systems. By means of three-dimensional scanning of surfaces, the laser scanner can record all spatial and surface geometry with millimetre accuracy with approximately one million measurement points per second. Much less time is spent in data recording, compared with other measurement methods. The resulting colour image of 3D measurement points shows an exact digital reproduction of existing conditions. Detailed 2D and 3D plans and complete 3D models can be created in a very short time with the precise data.
The compact size of the laser scanner was decisive for the award. It only measures 24 x 20 x 10 cm and weighs only 5kg. The Focus3D is thus highly mobile and usable at almost any location. In addition, it can be set up within a very short time.
Following the completion of a major contract involving the scanning and generation of a large chemical processing site, Advanced 3D Laser Solutions were the recent successful bidder for similar complex projects related to the scanning of five large UK fuel distribution terminals. Advanced 3D Laser Solutions client’s primary requirement was the preparation of precise piping isometrics for all terminal lines, in advance of inspections related to compliance with the Pressure Systems Safety Regulations.
Two advanced FARO Focus 3D Laser Scanners, supplied by Opti-Cal Survey Equipment, were used to accurately complete the in-depth site survey work. The easy to use FARO Focus Laser Scanner is the smallest and lightest laser scanner on the market and is the ideal tool for fast and exact indoor and outdoor measurements in three dimensions. Used throughout the world within the most demanding of conditions, the ultra-portable Focus Laser Scanner enables fast, straightforward, and accurate measurements of objects and buildings. It records architectural façades, complex structures, production and supply facilities, accident sites, and large-volume components.
FARO is the world’s most trusted source for 3D measurement, imaging and realization technology. Technology from FARO permits high-precision 3D measurement, imaging and comparison of parts and compound structures within production and quality assurance processes. The devices are used for inspecting components and assemblies, production planning, documenting large volume spaces or structures in 3D, and more. FARO’s 3D measurement technology allows companies to maximize efficiencies and improve processes.
The Focus3D X 330 offers an extra-long application range of 330m, whilst the Focus3D X 130model is a mid-range device offering precise scanning up.
Both scanner models are equipped with GPS and offer the ability to perform scanning even in bright sunlight. Remote scanning as well as almost limitless scan data sharing via SCENE Webshare Cloud makes the laser scanning solution truly mobile.
By the use of FARO’s Focus Laser Scanners and four sets of ‘Flexi’ spheres for target referencing between scans, Advanced 3D Laser Solutions’ experience in the field ensured that all surveys were completed with minimal impact to the sites’ efficient operation. In total, more than 1000 individual precise scans were completed across the five terminals. Typically, Advanced 3D Laser Solutions completed the site scanning of each terminal in 3-4 days. The collected point cloud files were then quickly converted into easily manageable 3D CAD files.
A scanner is not much use on its own – with SCENE software from FARO, all the scan data acquired on the set can be processed and – with the hosting service – securely shared worldwide.
FARO is a manufacturer of portable 3D measurement technology, and has developed the SCENE software package specifically for the FARO Focus3D laser scanner. However the SCENE software is not restricted to the laser scanners from FARO, but can also be combined with other makes of laser scanner.
Using this software, the user can process the photo-realistic scan data from the laser scanner with the aid of automatic scan registration and positioning methods, and then carry out measurements and 3D visualisations and export point clouds. New tools take care of automatic scan positioning without having to rely on artificial targets such as checkerboard markers or spheres. The range of functions of the software can be extended at will with plug-ins from the FARO 3D App Center, for example for creating a video, for volume calculations and much more. At the same time, FARO has published the new version 1.6 of the scan data hosting service, SCENE WebShare Cloud: This enables scan projects to be viewed, shared and published online. And all with the highest security standard.
SCENE is compatible with Windows from version 7, 64-bit, in addition to which at least a 512 MB graphics card with OpenGL-2.0-interface is required for optimum performance. For stereoscopic display, FARO recommends an Nvidia Quadro card. SCENE uses the manufacturer-independent, binary data exchange format ASTM E57, and the tool also supports all popular formats.
How many laser scanners should be used for a high-quality scan model of which magnitude?
Oliver Bürkler: The crucial factor is always the degree of detail required for a scan. The more accurate a scan is to be, and the higher the resolution it is to have, the longer the scanner takes to record the data. We are talking about a maximum of 15 minutes for a very detailed scan outdoors, within a surrounding radius of 330 metres. The larger and more complex the object to be scanned – for example a large, angular building – the more scans will have to be carried out in order to record all the surfaces. It can thus be an advantage in terms of time to employ several devices in parallel, but it is not absolutely necessary. As far as SCENE is concerned, the software can in principle handle projects of unlimited size, and map them with no restrictions.
How does the scanner store the data?
Oliver Bürkler: The scanner stores the scan data automatically on a normal SD card. If a computer is equipped with SCENE software, data transfer is started as soon as the SD card is inserted, following a brief request for confirmation.
There are two methods available for automatic scan positioning without markers: “Top View”-based registration and “Cloud-to-Cloud” registration. Which of these is suitable for which situation?
Oliver Bürkler: “Cloud-to-Cloud” registration uses all the scan data for registration. In order to be able to operate reliably, this type of registration needs in principle some initial information about the rough position and alignment of the scan. When outdoors, SCENE uses the GPS information saved by the scanner for each scan. Without this information, for example when indoors, the user has to align the scans roughly by hand in advance. In contrast to “Top-View”-based registration, this method requires a little more time but is potentially more accurate.
Prior information about location and orientation are not necessary for “Top-View”-based registration. This method is particularly suitable when there are enough vertical structures – such as walls, for example – available in the scan data.
However, in the case of targetless methods the user has to ensure greater overlapping between the individual scanning locations. So you need more scan positions but you save yourself the effort associated with transporting, fitting and managing the targets.
In which application situations is the use of targets as essential as ever?
Oliver Bürkler: SCENE still supports spheres and checkerboards as targets. The user will normally still want to use targets if he/she wants to georeference the scans, for example, with tachymeter data. The type of most suitable targets depends on the individual case.
In which formats can data such as image files, CAD drawings or cards be integrated into the scan data?
Oliver Bürkler: The user can import files in .tiff, Geotiff, .jpg or .png formats into SCENE. The software then displays the file on a horizontal plane in 3D space. In the case of a Geotiff file, the position and scaling are extracted automatically from the metadata. With the other file formats, the user has to enter the position and the scale of the image, for example by means of a dialog box.
Does stereo 3D viewing work in real time in every situation?
Oliver Bürkler: The output of a stereoscopic 3D view can be easily defined in the 3D settings of SCENE. A stereoscopic view is always possible without any time delay then.
Is SCENE WebShare Cloud permanently integrated into the software or an optional feature?
Oliver Bürkler: It is an optional service from FARO, but from the technology perspective it is fully integrated in SCENE. Advantages of the Cloud service include the easy viewing of scan data in standard web browsers, as well as the provision of data in any size. Users do not need any special software for it. The scans are also displayed as panoramic images, so no knowledge of 3D programs is required. That makes it particularly easy in the case of complex projects to provide access to the data to everyone involved – all without any time delay. Even changes to the project become visible in real time. There is the choice of making the data public or of restricting access by means of username and password.
Is web-based collaboration on the model also possible?
Oliver Bürkler: Yes, that is also possible. Although we recommend that a web conference system such as GotoMeeting or WebEx be used for that purpose when several people are working at the same time. It makes cooperation more effective.
You also offer a free version of SCENE, called Scenect. For which target group is it intended?
Oliver Bürkler: Our intention with Scenect is to appeal to people who are not typical professional 3D scanner users, and to offer them an easy way into 3D scanning. All that is needed are inexpensive sensors such as the Asus Xtion or Microsoft Kinect. With Scenect, however, only one sensor can be used at a time.
Are there any imminent plans for a Mac or Linux version von SCENE?
Oliver Bürkler: There will be no versions of the software for other operating systems in the immediate future. On the other hand, SCENE WebShare Cloud is entirely independent of the operating system.
SI2G S.r.l. (which stands for Sistemi Informativi Intelligenti p er la Geografia, or “Intelligent information systems for geography”) is a spin-off of Marche Polytechnic University established in 2008 by researchers with many years’ experience in the various disciplines involved in the study of terrain and the environment based on computer science and photogrammetry. The company deals with the acquisition, analysis, processing, archiving and distribution of “environmental data” in digital format, using an integrated systematic multidisciplinary approach. It provides services such as remote scanning of terrain, photogrammetry, topography, cartography and ICT.
Eva Savina Malinverni, Associate Professor of Topography at Marche Polytechnic University, explains how SI2G recently came to invest in a Laser Scanner Focus3D, the innovative laser-scanning tool from FARO that provides extremely precise yet simple 3D scanning
The FARO Laser Scanner Focus3D is actually a very compact device, weighing barely 5 kg and measuring just 24 x 20 x 10 cm. A technician can carry it around wherever and whenever it is needed. What’s more, the WLAN technology makes it possible to start, stop, view or even download scans remotely.
The imperial city of Huế, declared a UNESCO World Heritage Site in 1993, is probably the largest and most famous architectural site in all Vietnam. It was from here that the emperors of the Nguyen dynasty ruled from 1802 to 1945. Its design was based on the imperial palace of Beijing and comprises walls, moats, fortified gates, bridges and decorations that make it a truly atmospheric setting of great artistic and historic value. “Scanning it would have been very complex and time-consuming had we used the normal photogrammetry techniques.” The FARO Laser Scanner Focus3D, on the other hand, enabled the SI2G team to complete the work in just a few hours and to obtain truly astounding results with just 17 scans.
Thanks to the FARO Laser Scanner Focus3D, a highly flexible tool that is very quick and easy to use, the technicians at SI2G S.r.l. were able to scan the magnificent East Gate of the imperial Vietnamese city of Huế, capturing every detail of its form and geometry with the utmost precision, despite the difficult weather and operating conditions.
