Calculating Scattering Angles

[Edg422]

Hi, I would like to calculate the angle between the normal of the point and the vector made from such point and the sensor.

In CloudCompare this is called Scattering Angles, and it is inside the Sensor options. This is important to detect noise or "veils" made around some objects with laser scanners, and to filter out low presicion points (with scattering angles close to 90 degrees).

I hope you can implement this in CloudComPy. Thanks.

Hello, I haven't looked at the sensor part of cloudCompare yet and am not familiar with these treatments. I've been playing around a bit with CloudCompare to create sensors and calculate scattering angles, but I couldn't find an acquisition file with the sensor information in my raw data. Do you have any examples? In your case, how do you retrieve the sensor information? Could you briefly describe what you do with the cloudCompare GUI (which menu / options)? I will try to add what is needed in CloudComPy when I have a good understanding of the use case.

Thanks Paul
