    Abstract
  • Based on the theory of 3D reconstruction of space lines and through 3D reconstruction of scene space lines under photogrammetry system, the drawing plane of traffic accident scene was constructed by the least median of squares method, and the scene space lines' transformations from photogrammetry system space to road traffic accident drawing plane were completed.The examination and reconstruction of lines' parameters in road traffic accident scene plane were realized.Test was done to reconstruct drawing plane, middle line, right and left edge lines in the reference frame of photogrammetry system.The projective equations of middle line, right and left edge lines in drawing plane were calculated, and the lines were drawn in drawing plane.Test result indicates that the differences of angles among edge lines, middle line and x axis are less than 0.1°, and edge lines and middle line are almost parallel, so the measurement precision is exact.
