The above animation depicts a drivers point of view while travelling down the road at 50km/h and 30 km/h. The ability to experiment with different factors is an efficient way to identify and evaluate spatial and timing issues. If the theory of opposing counsel is known, it too can be previewed and evaluated. This is a very powerful tool which can provide insight into the strategy of the opposition and allow you to identify and… read more →
The use of digital video evidence is rapidly increasing in litigation. Precise reconstruction of accident scenes is possible using video footage from sources such as traffic cameras, security videos, vehicle “dash-cams” and even smartphones. The spatial information of any object seen in the video footage (including the camera itself) can be extracted for analysis, providing data for precise calculations of speed, motion, time and distance.
Photo Reconstruction and Analysis: Obtaining Measurements From Photos By introducing two-dimensional scene photographs into a three-dimensional computer environment, it is possible to locate and obtain precise measurements of any characteristics or features that are visible in photos but are no longer available at the scene (e.g. tire marks, road features, visibility obstructions). The images and video on this page show imported accident scene photos matched into a laser scanned digital environment for the reconstruction of… read more →

Scan data can easily be utilized to explore any spatial issue. Sight lines and environmental obstructions can be accurately evaluated. Viewpoints of drivers and witnesses can be identified, evaluated and demonstrated. Furthermore, objects within the scene can be removed or introduced, allowing exploration of various ‘what-if’ scenarios. For instance, it would be possible to evaluate the difference in visibility down a tree-lined street versus the same street with the trees digitally removed, or for various… read more →
Damage visualization with coloured deviation map. Vehicle Damage Analysis Complex and curved surfaces are notoriously difficult to document using traditional methods. A laser scan captures the spatial information of complex surfaces quickly and accurately. Point by point measurement of vehicle damage can be a time-consuming task. Comparing a scan of a damaged vehicle to a scan of an undamaged vehicle of the same make and model can assist when assessing damage for accident reconstruction. The… read more →
Granville Island Scan To scan a section of road and bridge under Granville Island, we used a Trimble TX5 for 11 scans at 1/4 resolution. The data collected by scanner is so dense that most computer systems and software packages can not handle it without decimation (reducing the density of points) . For example, in this case, 484 million points were scanned in total, and the point cloud exported for use in the video contains… read more →
Putting the Pieces Together Scans can be combined to assist engineers and investigators with determining the chain of events of a collision. In this video, all three vehicles were kept in different holding facilities and scanned separately. The environment – an industrial area of Vancouver BC – was also scanned at a much later date than when the accident occurred. The scanned vehicles were imported into the scanned digital environment and moved into position. From… read more →
Strathcona Industrial District The video features a scan data fly-through of 6500 square metres of an industrial area located next to Strathcona Park in East Vancouver. Multiple scans are needed to fully capture a location. Each white circular shape on the ground represents a location where a scan was conducted. Scans are then aligned using the white spherical targets seen in the video. Site map: scanner locations are indicated by the coloured circles in the… read more →
Sam Kee Building in Historical Chinatown, Vancouver BC This video features one of Vancouver’s most recognizable intersections: West Pender and Carrall Street in historical Chinatown. Built in 1913, the Sam Kee building is one of the main tourist attractions in Chinatown. At only 1.83 m wide, this heritage building holds a world record for being the world’s narrowest commercial building. Also visible in this scan is the Millennium Gate and the Chinese Cultural Centre.
