A Stereo Photographic System For Motor Vehicle Accident Investigation
C G Bryner · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1973
A variety of photographic instrument systems have been studied to determine an optimum technique for supplementing or replacing manual methods for obtaining map data for auto collision sites. These systems include (a) a single camera perspective-grid system (Ref. 1), (b) the elevating of an overhead camera on a truck mounted boom (Ref. 2), and (c) twin camera stereometric camera systems produced in Europe (Ref. 3). The European systems are factory produced and represent equipment fabricated to exacting standards capable of producing plotted data to prescribed standards. Such units are tripod mounted or designed to operate from an elevating post mount in a vehicle.
