A Simple Calibration and Verification Method for Solid-State Lidar

为了解决固态激光雷达外参标定繁琐与验证其标定结果较为困难的问题,提出了一种面向固态激光雷达的简易标定与验证方法.该方法设计了一种简易的标定场和标志物,随后利用标志物完成激光雷达的角度标定,再通过测绘方法完成激光雷达的距离标定,以此来减少角度外参与距离外参的相关性,并保证标定结果的精度.最后通过比较计算得出外参误差,验证激光雷达标定结果.实验结果表明该方法合理有效,且大幅减少了激光雷达标定和验证结果所需要的设备准备时间和成本,具有一定的应用价值.

In order to solve the problem of cumbersome external parameter calibration of solid-state lidar and overcome the difficulty in verifying its calibration results, a simple calibration and verification method for solid-state lidar is proposed. This method designs a simple calibration field and markers, uses the markers to complete the angle calibration of the lidar, and completes the distance calibration of the lidar by using the surveying method, so as to reduce the correlation of the external parameters of the angle and the distance, and to ensure the accuracy of the calibration result. Finally, the error of external parameter is obtained through comparison and calculation, and the calibration result of the lidar is verified. The experimental results show that the method proposed is reasonable and effective, and greatly reduces the equipment preparation time and cost required for lidar calibration and verification results, which has a certain application value.
