Incorrect pose conversion code
I think the conversion function from LLFF to OpenCV is somehow incorrect.
The correct version (after using this code, the poses & reconstruction look correct to me from COLMAP)
def convert_llff(pose):
hwf = pose[:3, 4:]
ext = np.eye(4)
ext[:3, :4] = pose[:3, :4]
ext = np.concatenate([ext[:, 1:2],
ext[:, 0:1],
-ext[:, 2:3],
ext[:, 3:4]], axis=1)
mat = np.linalg.inv(ext)
return np.concatenate([mat[:3, :4], hwf], -1)
