About intrinsic matrix and external matrix.

I can't find any files like:
└── intrinsic
└── asus.ini

Besides, what's the external matrix of the image in /scenenn/images.

Thanks!

Hi, I believe the files you are looking for are located here: http://103.24.77.34/scenenn/main/intrinsic/
Also, I'm not sure but there seems to be only 1 camera, so no extrinsic parameters but a trajectory.log file for each scene.
Hope that helps !

Hi, thanks for your answer. I sample points on the mesh, and try to find the extrinsic of the image to points, which is the extrinsic what I mean. I thought it is identity matrix because the mesh was align to the image, but when I project the points to the image with identity matrix, it is wrong.
