Traffic accident investigation requires detailed documentation of the accident scene, vehicles, and persons involved in the collision. To adequately document an accident scene, investigating officers accurately record various measurements (e.g., skid marks, dimensions of different highway geometric elements, etc.). Typically, a measuring tape and/or a total station (theodolite) are used to obtain the needed measurements. Advances in digital imaging and computer technology make it possible to develop cost-effective traffic accident investigation system alternatives that provide sufficient accuracy, significant time savings, and reduced costs. Utilizing stereo machine vision technology an accident investigation system, called the UNL Traffic Accident Investigation Tool (TAIT) consisting of two digital cameras and measurement-extraction software tool were developed in this project. |
