About calibration, detection failed. #14

Open zhanghao-py opened 7 years ago

zhanghao-py commented 7 years ago

Thank you for excellent work. However, I am confused about some details of calibration and there is my question as follows.

  1. I followed the instructions and experiment failed (detection fails). Do you have any suggestion to debug detection results with cv and pointcloud throughout visualization? I found the cv result of circles detection is commented (Image.cpp:174-197), and how about pointcloud?

  2. Maybe, there is something wrong with my 3d marker. Do you have any advice upon 3d marker fabrication?

  3. What is the relationship between but_calibration_camera_velodyne and but_velodyne_lib? CMakeList.txt within but_calibration_camera_velodyne doesn't contain any librarian (.so) in but_velodyne_lib. Could I compile but_calibration_camera_velodyne without but_velodyne_lib?

Thanks.

How about Calibration3DMarker.cpp:159 ( //view(plane); )?
