“…The use of close-range photogrammetry has been validated for reconstructing the 3D geometry of vehicles [3,4,6,8,10,12,14,21,22,31,37,42]. While the cost of equipment is less and the equipment more portable compared to some of the aforementioned methods, traditional closerange photogrammetry requires extensive processing time, in which the analyst must manually identify and cross-reference desired point locations in multiple photographs in order to calculate points of interest.…”

“…The comparison to total station survey methodology was selected as it is widely-accepted in the field of collision reconstruction and it often considered the "gold standard" for three-dimensional vehicle coordinate measurement. Traditional photogrammetry was selected because it has been validated for both general data capture and specific application to vehicle/scene documentation for collision reconstruction using photographs and postprocessing software [3,6,8,10,12,14,21,42]. Like photo-based 3D scanning, traditional photogrammetry can generate a single point cloud for the entire vehicle, thereby allowing direct comparison with the complete photo-based 3D scanning model of the vehicle.…”

An experiment was conducted to examine the validity of freely available photo-based 3D scanning software for generating accurate 3D geometry of a vehicle. Currently, 3D vehicle geometry is routinely captured using total station survey equipment, coordinate measuring machines (CMM), laser scanning, or traditional point-based photogrammetry. While these methods produce sufficiently accurate results for collision reconstruction, they have limitations that can affect practical implementation. For example, manual surveying with a total station, CMM or traditional photogrammetry are all limited to the production of coordinate data at discrete, predefined points. In addition, total stations, CMMs and laser scanning devices are also expensive and require a significant amount of time in the field with the vehicle. In contrast, photo-based 3D scanning allows a 3D mesh to be created of a vehicle simply from a series of photographs using a consumergrade digital camera.
