I can't detect my chessboard in the point cloud

Hello everyone,
So I was trying to calibrate my lidar and camera using both the app Lidar Camera calibrator and the script in Lidar and Camera Calibration - MATLAB & Simulink - MathWorks France. I was able to detect the chessboard corners on the images but I couldn't detect it on the point clouds (pcd file with x y z values with 32000 points) associated, and I was wondering if it's due to the noisy point cloud and so we must do a preprocessing to the data, or there is any other solution. I have tried multiple positions to place the chessboard (near the lidar, far ) but in all of them it didn't manage to detect the rectangle.

Hi Mehdi,
As per my understanding, your checkerboard is not getting detected in the point cloud.
Please ensure that you are following the data capturing guidelines as per the following documentation
Further you can also tune the name-value arguments of the “detectRectangularPlanePoints” as per the following documentation:
Hope this helps :)
