Stereo Processing of Images Set from a Car Video Recorder

Three-dimensional geospatial data are actively used for monitoring highways and controlling traffic accidents. In accident management, this data ensures an objective assessment of situations. There is potential to use car video recorders (DVRs) to enhance the productivity of three-dimensional measurements of road situations. The experience of developing and using algorithms within a domestic digital photogrammetric system is presented below. These improvements are based on a cylindrical stereo pair of DVR images and are designed for three-dimensional measurements and the creation of orthophotos of road surfaces. The article describes the step-by-step photogrammetric processing of DVR images from start to finish using the developed stereo pair. The proposed method of three-dimensional measurement is accurate, allowing for the measurement of road infrastructure objects, the measurement of distances between them, and the assessment of traffic accident monitoring.
