| Abstract: | According to the accuracy of calibration for the current session LiDAR,this paper put forward its own error detection methods of laser diode current intensity,scan half-angle,scan frequency,scan distance and the gray value that have significant impact on the ranging accuracy after the analysis of the LIDAR range measurement principle and the factors that influence the ranging precision,shows signs of a special point cloud,and thus organizes the integrity of the calibration to validate the feasibility of the methods.It presents the notes for the detection that can be referenced,providing referencial basis for adding the error correction in the measurement results. |
