How to obtain key point text files for point clouds #8

Closed Tcode8 closed 7 months ago

Hello author

I would like to ask, how can I obtain the required key point text file when I only have point cloud files?

Hi @Tcode8, The kpts txt file contains point indexes of 5000 randomly sampled points. Yours,

Hi @Tcode8, The kpts txt file contains point indexes of 5000 randomly sampled points. Yours, Thank you for your reply！. So, in the case where I only have two. py files, can I simply randomly sample some points as key points for registration?

Yes, you can.

Thank you very much for your reply. It has helped me a lot！

Yes, you can.

Hello, May I ask what does the data in the ratio.py file in the code represent? How can I obtain this file, especially if I only have point cloud files?

Hi @Tcode8, Do you mean the "ratio.npy" file used in Test_cycle.py? It is estimated and output by Test.py.

Yours,

I'd like to ask, what is the Rotation.npy file needed when extracting YOHO features? How can I obtain this file? Also, if I only have multiple point clouds, can I achieve obtaining the registered point cloud by just inputting the point cloud files? Looking forward to your reply thank u！
