how to check the point cloud alignment RMSE

I want to check the accuracy or rmse for alignment of point cloud. I use stero camera calibrator app and try to reconstruct the sence i want calculate RMSE point cloud data. so i have come to know either my point cloud or despirty map is valid or not

Hi Bushra,

To verify the accuracy of the RMSE value and the correctness of the disparity map, you can keep below mentioned points under consideration:

• The points cloud data should be aligned.
• Try to remove any noise or outliers from the point cloud data.
• Confirm that both the point cloud data and ground truth cover the same area to ensure accuracy.

In addition to these, for disparity maps correctness, you can check the reprojection error by reprojecting the left and right images and checking the alignment.

For more information on disparity maps, you can refer to the MATLAB Documentation of 'disparity' and 'disparityBM' functions:

• disparity: https://in.mathworks.com/help/vision/ref/disparity.html
• disparityBM: https://in.mathworks.com/help/vision/ref/disparitybm.html

I hope this helps in resolving the issue.
