%X In order to avoid the distortion of the real situation reconstruction,and on the basis of related theory of noise removing,some researches are taken and three noise elimination algorithms for terrestrial 3D laser scanning data with priori information,utilizing the points labled with height as the priori information are presented,elevation of interpolation,fitting plane or trend surface with Least-square method being compared,and choice of proper threshold to eliminate noise.The experimental results indicate...
