This example shows you how to estimate the rigid transformation between a 3-D lidar and a camera. At the end of this example, you will be able to use the rigid transformation matrix to fuse lidar and camera data. This diagram explains the workflow for the lidar and camera calibration (...
手眼标定法是标定摄像头与机械臂的一个经典方法,不过这个思想也适用于其他传感器,比如自动驾驶中激光雷达与摄像头之间的标定,比如东京大学的这篇工作《LiDAR and Camera Calibration using Motion Estimated by Sensor Fusion Odometry》。 手眼标定法的核心公式只有一个, ,这里的 X 就是指手(机械臂末端)与眼(摄像头...

Lidar Toolbox™ provides lidar camera calibration functionality through the command line interface and Lidar-Camera calibrator app. This helps to find transformation between camera and lidar in a system which is an essential step in combining data from lidar and a camera. Cameras provide rich color...

Lyu开发,用于校准LiDAR到摄像机的转换。 这个基于MATLAB的工具箱搜索LiDAR帧序列中的拐角点,请求在相应的图像中进行注释,然后使用通用算法估算转换参数。 特征: 它确实需要任何棋盘格或特殊对象,唯一需要的是一块纸板(亚马逊盒子就足够了)。 键入简单的阈值过滤器后,工具箱将自动检测纸板的上角并搜索相应的图像。 要...

'save_path': the parent folder where you save the paired images and point clouds You can also run theconvert_intrinsic_into_yaml.mto convert the intrinsic parameters into yaml file, which can be used in theimage_procROS package. Lidar Camera Calibration ...
You must save point cloud data in the PCD or PLY format. Image files can be in any standard image format supported by MATLAB®. For more details on the calibration workflow, see theLidar and Camera Calibrationexample. Related Examples
