Num of geometric registration fragments #29

Hi, Thanks for your sharing. In your project website you mentioned that the ply file for geometric registration fragments Each fragment is a 3D point cloud of a surface, integrated from 50 depth frames using TSDF volumetric fusion, and saved to a .ply file. But I found the number of ply file does not equal to the rgbd images / 50. For example there are 10204 color images and depth images in sun3d-hotel_uc-scan3 dataset, but only 54 ply files is provided in the geometric registration benchmark. So do you just use part of rgbd image to generate ply file or maybe I miss some information?

Looking forward to your reply. Thanks a lot.
