中文摘要：

以空间直线的三维重建原理为基础,通过现场空间直线段在摄影测量系统空间下的三维重建,实现了道路交通事故现场图绘制平面的最小中值二乘拟合,并完成了现场空间直线从摄影测量系统空间向道路交通事故现场图绘制平面的转换,实现了道路交通事故现场平面直线参数的检测和重建。对摄影测量系统世界坐标系下现场图平面、中心线及左、右边缘线的三维重建进行了试验,并得到了中心线及左、右边缘线在现场图平面上的投影直线方程和投影图。试验结果表明：左、右边缘线和中心线在现场图平面上的投影与x轴的夹角之差均小于0.1°,道路的边缘线与中心线基本平行,测量精度较好。

英文摘要：

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.3 tabs,4 figs,11 refs.
