Re: M3C2 point cloud projection

I reproject the vector from the core point to the neighborhood point onto the normal by calculating the cosine Angle between the two vectors.

By the way, can you tell me how are you doing the projection?

Looking forward to your reply.

Re: M3C2 point cloud projection

Sorry, I didn't make myself clear.

I reproject the neighborhood points(which is already the distance along the axis) onto the normal by qM3C2Tools::ComputeStatistics, Why will produce different results,

I will wait for your reply. Your help will be very useful to me.

Re: M3C2 point cloud projection

Hi Daniel, Thanks for the reply, Your answer is very helpful to me. I have to ask a question, By qM3C2Tools::ComputeStatistics function, I will again neighborhood point projection in line (normal, neighborhood point to the current core point, the two vector), why will produce different results, of c...

M3C2 point cloud projection

Hello! I've read paper named 《Accurate 3D comparison of complex topography with terrestrial laser scanner: Application to the Rangitikei canyon (N-Z)》. Besides, I've researched the code of M3C2 algorithm in CloudCompare. It's so helpful that I've learned a lot from that. However, I'm confused. In th...
