3D Point Cloud Data Reconstruction Issue from Saved Files using Open3D

[youb1649]

I am trying to save the data obtained from a 3D point cloud into files (RGB, Depth, intrinsic, extrinsic) and then read those saved file data to reproduce it in Open3D. The reproduction program does not use the hl2ss programs, and the code seems fine, but the 3D reconstruction is not working properly. Do you have any advice for me or can you point out any potential errors in the program?
