Abstract. The article considers the methodology of the assessment of the correct record of a traffic accident in the video materials of the car DVR. The need to address such issues arises during the investigation of road accidents, when it is required to establish the linear and angular values of various objects, as well as the vehicles’ and pedestrians’ speed based on the video recording materials. The article provides a methodology for the comparative analysis of linear and angular values between stationary objects on the location and recorded in the video recording materials of a car DVR applied in a real case. To assess the correct linear values recorded by a DVR, photogrammetry methods are used. To analyze angular values, geodesical angle fixation methods are used, where stationary objects located at an alignment are used as the base. The speed of dynamic processes is estimated by the frequency of video recorded frames using an electronic synchronizer.
Keywords: video recording; car DVR; traffic accident; correspondence of linear and angular values; photogrammetry.
