Reconstruction of a video recorded pedestrian accident, using the Photorect 2.0 software

Summary/Abstract: Increasingly, evidence of a road accident includes video recordings that provide useful material in the work of an expert witness. The analysis of the recorded course of the event is the most reliable basis for accident reconstruction, including the speed and actions taken by the participants. An effective use of a video recording for a road accident analysis usually requires at least its initial processing, e.g. framing and removing unnecessary parts. In order to improve the quality of the source video material in terms of mapping the geometric features of the objects recorded on the film, it is necessary to correct the distortion, followed by orthorectification. It is also often necessary to improve the image by applying filters to the video recording. These operations are possible with the use of Photorect 2.0, which is discussed in the article. The transformed video, post-processed by means of perspective effect elimination, cropping and frame extraction was used for the preparation of a computer simulation of the event, synchronized with this film.
