Abstract: When using 3D laser scanning to obtain the moving and deformation of highway in the mining area,because there is no observation point, the light pole on both sides of the road are selected as the characteristic features, through the comparison of different time coordinates change of light pole center axis, calculate the horizontal movement and deformation of highway. According to the characteristics of the point cloud of the light pole, We derived extraction model of central line of street lamp pole, using genetic algorithm to extract the central line of the street lamp pole, and analyzed the influence of the random error, gross error and the point cloud observation is not comprehensive on the extraction of the central line of the algorithm. The research results show that the method of calculating the coordinates of the center of the road lamp accuracy better than 1mm, and has strong anti-interference ability.
