OpenCV makes it pretty easy to get the position of all four corners of the Aruco marker relative to the camera. The ArUco decoding algorithm is capable of locating, decoding, and estimating the pose (location and orientation in space) of any ArUco markers appearing in an image. ArUco - Download. Application Programming Interfaces  120. Libs. The lidar_camera_calibration/pointcloud_fusion provides a script to fuse point clouds obtained from two stereo cameras. Detect markers with a single line of C++ code. For example in ARToolKit there is a possibility to create new marker patterns and train them using mk_patt.exe, which generates pattern file that can be used to detect the pattern. Choose between ChArUco, checkerboard (chessboard), and (asymmetric) circles grid. Good First Issues ( 0 ) Pull Requests to Review ( 5 ) Package Description. We need more information.
