Abstract：Although preprocessing surface point cloud data obtained by airborne LiDAR measurement technique can correct some systematic errors, the output point cloud data may still have some remnants of systematic errors between air stripes. Therefore, the errors must be checked and corrected prior to the utilization of DEM and other related digital products obtained from airborne LiDAR data. This paper thus analyzed several adjustment methods, summed up the technical process of strip adjustment based on the twelve-parameters model, and compared the results of studying the problem whether the ground control points are needed or not after the adjustment. It is shown that adjusting with ground control points can not only improve the internal accuracy but also improve the external accuracy effectively.
