【摘要】 采用 2种方法对激光束投射到路面上时产生的光斑及其在 CCD光敏面上产生图像进行了实际分析 ,并得了出当路面的高差发生变化时 ,在光面上的光斑质心与高差之间的关系 ,提出了产生测量误差的原因及解决的办法更多还原

【Abstract】 Two ways are used to make practical analysis on the light spots of laser beams which irradiate on road surface, and its images appear on the photosurface of CCD. The results show that there is a relation between barycenter of light spots and superelevation. The highway surface can be measured according to the relation. The solution for measuring errors is presented.更多还原
