US Patent 6850843 Accident evidence recording method

A mobile accident recording system (40) includes a GPS receiver-pole (41) and a computer (14) which prompts investigator to place a tip of the receiver-pole on identified position points of evidence items at an accident site to measure and record coordinates of the position points. Data including the recorded coordinates and stored database information for each evidence item are processed to reconstruct a graphical three-dimensional representation of the accident site which is displayed to the investigator from any desired advantage point selected by the investigator.
