I use a model which exported from MicroStation to do clash detection with point cloud in pointools.
after I perform the test, all of the point cloud seem to clash with the .obj model.
Pic above, there are the point cloud and the model object.
Pic above, there is the settings for the test, all of the settings are default.
Pic above we can see that even the points with a long distance from the object, the results still shows like they are clash each other.
But the object was only move on the road surface in a very short distance.
I changed another dataset to test, the results are similar.
