    Abstract
  • In order to survey traffic accident scene rapidly, a 3-D reconstruction model of traffic accident scene based on self-calibration using general digital camera was explored.The model was based on fundamental matrix, which was estimated by matched feature points, essential matrix can be calculated by it.Traffic accident scene was reconstructed after essential matrix was decomposed.It is proved that the traffic accident scene can be reconstructed without calibration reference points in scene, the difference between the reconstruction result and real 3-D data is only a scale factor.
