Opencv intrinsic calibration
WebThe intrinsic parameter calibration should be run camera by camera, where each recorded video sequence should be focused in covering all regions of the camera view and repeated from several distances. In the extrinsic sequence, this video sequence should be focused in making sure that the checkboard is visible from at least 2 cameras at the time. Web9 de abr. de 2024 · lidar_imu_calib 概述 在基于3D激光雷达的slam开发中，我们经常使用imu为匹配算法（icp，ndt）提供先验，因此需要校准激光雷达和imu之间的变换。对于匹配算法，transfom中的姿态比变换中的位置更重要，并且通常将位置设置为0。因此，此回购专注于在激光雷达和imu之间的转换中校准姿态分量。
