Our aim is to detect small changes in the range of 0 – 10 cm. We have tried several tests with different scales in the order of 0.03≤D≤0.1 m and 0.04≤d≤0.1 m. Unfortunately, the “red-blue” effect was reduced but didn’t disappear. Doing further tests we have discovered that this problem may be relate...

Yon can see the global orientation and the scale in the images attached below. Moreover, I've got the following parameters using the 'auto' button of M3C2: D = 0.038541 m, d = 0.077082 m, Max depth = 1.287666 m.

Thank you again.

Dear admins and users, I'm a new user of CloudCompare. After I red the scientific paper on the M3C2 algorithm, I'm trying to estimate mathematically the scale D and the projection d on my point clouds. For this purpose I've tried to calculate the mean roughness sigma(D), using the tool, on the refer...
