capture error about cam_lidar_calibration

Hi bro,
It seems that you didn't extract the correct chessboard point cloud.
You shoud adjust the threshold to make sure only the chessboard's pointcloud appear in rviz, with as little outliers as possible.
Hope it helps.

I adjusted already but the problem is still there.
