AAAI2023,implementation of "READ: Large-Scale Neural Scene Rendering for Autonomous Driving", the experimental results are significantly better than Nerf-based methods
Hi, I wonder what does proj_matrix do to the points (especially col 3 and col 4) and why do not use intrinsic matrix to project the points directly
proj:
2 fx / w, 0, 1 - 2 cx / w, 0
0, 2 fy / h, 2 cy / h - 1, 0
0, 0, (zfar + znear) / (znear - zfar), 2 zfar znear / (znear - zfar)
0, 0, -1, 0
We need to ajust the intrinstics matrix into the OpenGL format(using the ndc coordinates), the more infomations you can read from here, note in GL_PROJECTION part
