The static calibration and analysis of the Velodyne HDL-64E S2 scanning LiDAR system is presented and analyzed. The mathematical model for measurements for the HDL-64E S2 scanner is derived and discussed. A planar feature based least squares adjustment approach is presented and utilized in a minimally constrained network in order to derive an optimal solution for the laser’s internal calibration parameters. Finally, the results of the adjustment along with a detailed examination of the adjustment residuals are given. A three-fold improvement in the planar misclosure residual RMSE over the standard factory calibration model was achieved by the proposed calibration. Results also suggest that there may still be some unmodelled distortions in the range measurements from the scanner. However, despite this, the overall precision of the adjusted laser scanner data appears to make it a viable choice for high accuracy mobile scanning applications.

通过Patten Planes对Velodyne HDL-64E LiDAR 激光雷达的测量数据进行修正和校准。以便更改点云图的错误。This work describes a method for calibration of the Velodyne HDL‐64E scanning LIDAR system. The principal contribution was expressed by a pattern calibration signature, the mathematical model and the numerical algorithm for computing the calibration parameters of the LIDAR. In this calibration pattern the main objective is to minimize systematic errors due to geometric calibration factor.

Recent progress in the cartography market can only be described as radical. The time-consuming days of mapping by hand seem numbered, as geographic information system (GIS) experts, professional land surveyors (PLS) and others within the field of cartography awaken to the advantages of integrating light detecting and ranging (LIDAR) into their mobile mapping systems. LIDAR is similar to radar, except that the sensor sends out and receives....................
