WebMar 26, 2024 · Abstract. Point cloud registration is the basis of real-time environment perception for robots using 3D LiDAR and is also the key to robust simultaneous localization and mapping (SLAM) for robots. Because LiDAR point clouds are characterized by local sparseness and motion distortion, the point cloud features of coal mine roadway … WebIMU Preintegration¶ To perform preintegration, GTSAM conveniently provides us with an object called PreintegratedImuMeasurements. This object requires various parameters …
