Development of Coordinate-machine of the Scene of Road Traffic Accident based on Binocular Stereo Omni-Directional Vision Sensors

On the basis of analyzing flaws of the traditional means of traffic accident scene survey and inadequate of the existing photogrammetry technique, this paper presents a panoramic stereo photogrammetry technology applying to traffic accident survey. By employing the result of photogrammetry, the drawing module can automatically draw traffic accident scene diagrams for the accident analysis and reconstruction, so as to quickly achieve the purpose of measurement and drawing.Experiments show that the presented accident scene coordinate-machine can measure the distance and the azimuth of all the relevant objects on the accidental scene, and enjoys the advantages of high precision in measurement, convenience in operation and carry, no necessity in calibration,etc. So it can meet the traffic police's needs of the measurement and drawing of the traffic accident scene.
