Abstract

Abstract

This paper presents a new algorithm for self-calibration of spiral scanning airborne laser radar system. Firstly, the mathematic model of the point cloud location of the spiral scanning laser radar is deduced. Then the surface features of the overlapping area of the laser radar point cloud data is extracted, and the feature of the laser radar calibration model is constructed. Finally, the influence of the placement angle error on the forward and backward scanning data is analyzed, The plane parameters and the placement angle are estimated based on the regional network adjustment method by using the same name surface feature. The experimental results show that this method realizes the self-calibration of the placement angle of spiral scanning airborne laser radar system, and the absolute accuracy satisfies requirement of the production data.
