Abstract: In order to meet the needs of mapping the accident scene diagram on the scene for traffic police, a real time mapping method for traffic accident scene investigation based on image guide was proposed. The proposed procedure consists of a transformation which transforms a single photo of the accident scene from perspective image to orthographic image using direct linear transformation method, followed by mapping accident scene information such as vehicles, bodies, fall out objects, braking traces and so on directly over the orthographic image, and finally printing out the accident scene diagram, which needs to be signed by interested parties. A typical traffic accident case was used to validate the proposed method. Compared with the traditional handson measurement, the proposed method can not only improve the accuracy of site investigation, but also can considerably reduce the time of onscene data processing and drawing, which contributes to satisfying the requirement of printing out the accident scene diagram in real time.

Key words: accident reconstruction, traffic accident, accident scene investigation, direct linear transformation, photogrammetry
