Nuclear Safety – Remote Deployment of Laser Scanners in Contaminated Environments

Figure 1: A Point Cloud is generated by using a 3D laser scanner. In radioactive controlled environment robot mounted scanners can be driven to position.

 

A key safety issue in the operation of any nuclear reactor or nuclear waste management site is the control and containment of radioactive material, making risk assessment and management by means of regular inspection a vital element as much as a regulatory requirement.
By Yoldas Askan, Nuclear Future, 4/2011

Given the challenges of working in radiation controlled environments and with limited choice of non-contact, remote examination techniques available, visual inspection has so far been most widely used technique despite its limitations to the detecting of obvious flaws, requiring good eyesight and illumination, and findings are often subjective and dimensionally uninformative.

In recent years, remote deployment of laser scanners in contaminated environments has allowed acquisition of more precise survey data. By the systematic emission of millions of laser beams, a 3D Laser Scanner (e.g. FARO’s Focus3D) collates accurate measurements of distances to objects, producing a 3D model often referred to as the “Point Cloud”.

Construction monitoring with the 3D laser scanner

Construction monitoring is one of the key applications of the 3D laser scanner. Starting with the inspection of the foundation excavations through to the weekly monitoring of the building shells, the laser scanner enables time and cost-efficient working. Any discrepancies between the building under construction and the existing plans are monitored. In this article we show how the laser scanner helps with construction monitoring and the advantages that are offered by the laser scanner compared with conventional measuring instruments.

Surveying the property using a 3D laser scanner

Monitoring the progress of an office building using the 3D laser scanner

A job in the construction industry might involve monitoring the progress of an office complex. The excavation for the foundations has already been completed. The client requires weekly documentation and monitoring of construction progress for legal and technical documentation. The property is a modern design with lots of free-form surfaces. Conventional measuring instruments cannot measure it comprehensively. Laser scanners are predestined for this purpose. They are also suitable for documenting any discrepancies between the existing building and the planning documents. Laser scanning saves time and money. With the appropriate software it is also possible to produce new plans if necessary.

Building Information Modelling using the FARO Laser Scanner Focus3D

eBIM using the FARO Laser Scanner Focus3D

Building Information Modelling is the biggest change in the construction sector, since CAD replaced hand drafting. Existing Building Information Modelling (eBIM) is the first step in the BIM workflow for retrofit & refurb projects.

BIM was developed as a way of managing the full development lifecycle of a building project. Used to facilitate new designs, build changes and communication amongst contractors and design teams, it has provided significant cost savings and efficiency gains. As these methods have become more robust, companies have looked to apply these techniques to a range of projects. Combined with the current downturn in the new build sector, many firms have seen the majority of their construction work switch to retrofit and refurb projects instead of new build. [Read more …]

Reconstructing Dinosaur Fossils Using the FARO Laser Scanner

 

Reconstructing Dinosaur Fossils Using the FARO Laser Scanner

Reconstructing Dinosaur Fossils Using the FARO Laser Scanner

Paleontologists from the Sam Noble Oklahoma Museum of Natural History are working towards reconstructing the anatomy of missing bones of a juvenile Apatosaurus. With approximately only 15% of the bones collected, scientists look to digitally reconstruct the rest of the bone structure using the model of the adult Apatosaurus currently on display in the Museum. Reverse engineering the large skeleton would be the best solution.

Challenge

The Sam Noble Oklahoma Museum of Natural History is home to one of most extensive paleontology collections of prehistoric specimens. Much of the scientific research for the museum is conducted by the Center for Shape Engineering and Advanced Manufacturing (SEAM). SEAM is a multi-university collaboration that has pooled together engineering resources to focus on creating and disseminating innovation. As one of SEAM’s members, the University of Oklahoma has been recently working with the Sam Noble Oklahoma Museum of Natural History in a very unique application.

The paleontologists of the museum were tasked to reconstruct the anatomy of a juvenile Apatosaurus. Since only 15% of the bones had been collected, the remaining fossils would have to be anatomically created by the team of scientists. Traditionally, sculpting clay models by hand has always been common practice. However, using this process is extremely time consuming, often inaccurate and highly irreproducible.

As part of SEAM the University of Oklahoma assisted the museum’s paleontologists by providing an alternative solution. The university’s objective was to provide individual prototypes of each individual bone of the juvenile Apatosaurus for the paleontologists to create castings for the display model. The team decided to reverse engineer the current adult Apatosaurus skeletal model so they could proportionally create the missing bones of the juvenile dinosaur.

Rulers are a thing of the past: the future belongs to 3D laser scanners

The future belongs to 3D laser scannersArchitects and civil engineers require millimetre-precise survey data for their work. With traditional measuring devices the measurement of a building or site is a tedious and complex process. Modern 3D laser scanners are time-saving and cost-efficient – and not only in the field of architecture. In our blog we will introduce you to this innovative technology.

3D laser scanners: tomorrow’s survey technology
For a long time yardsticks, spirit levels and theodolites were the only option for measuring buildings or sites. Surveying was simplified by laser measuring devices that indicated the distance between two points. With modern 3D laser scanners it is now possible to measure a real building and construct a virtual model in just a few steps. The leading laser scanners record up to one million data points per second. Within a few minutes they create a complex image of their surroundings. Architects’ drawings, floor plans and elevations etc. can be created with the survey data. The 3D laser scanner technology is quicker and more cost-efficient than conventional methods of documentation.

Using enhanced reality to bring our cultural heritage to life

Using enhanced reality to bring our cultural heritage to life

The use of enhanced reality has rapidly become part of everyday life. This new technology, which enables the superimposition of virtual elements onto reality, is rapidly gaining in popularity. In the cultural heritage sector and museums, it opens up new options for presenting sites and works of art. It is thus possible to display missing or lost elements, to provide complementary information, and to reconstruct historical scenes and décor in a manner that is at once spectacular, playful and educational. ART GRAPHIQUE ET PATRIMOINE (AGP) uses FARO for exceptional presentations. One example is the enhanced reality replication of the study of Charles V, at the Château de Vincennes, as it was in the 14th century.
