Meaning of parameters in rendering/camera_calibration.txt file for each shape #11

Closed morsingher closed 1 year ago

morsingher commented 1 year ago

Hi, thanks for open sourcing your work! I would like to get the intrinsic camera matrix for each rendered view and I have noticed there is a rendering/camera_calibration.txt file for each shape. In this file, there are three parameters, but I can't understand their meaning. Can you help me to decode such values and build the 3x3 calibration matrix?

@morsingher , hello, where did you find the camera_calibration.txt file? After downloading and extracting the dataset, I cannot find this file, could you send me this file? Thanks a lot.

@zhanghm1995 Have you found the camera_calibration.txt?

@tpzou ，I cannot find these camera_calibration.txt files? So are you also cannot find these files?

In ShapeNet-ViPC, I rendered only the GT and partial point cloud. The view data is inherited from ShapeNetRendering. For more information about ShapeNetRendering, you should check https://github.com/chrischoy/3D-R2N2 .
