How to get the intrinsics and extrinsics parameters of the camera

[yjcaimeow]

Hi @dirkgr @schmmd @iellenberger @MLatzke @pdasigi

I successfully obtain the rendered image as follow the steps. But I didn't find the camera intrinsic and extrinsics of the 12 images. Could you please share the code for how to get the accurate parameters?

Best, Ying

In the "save_images" method, add the following code:

# save the c2w matrix
c2w_matrix = np.array(cam.matrix_world)
m_output_dir = os.path.join(args.output_dir, object_uid,'pose')
os.makedirs(m_output_dir, exist_ok=True)
with open(os.path.join(args.output_dir, object_uid,'pose', f"{i:03d}.txt"), 'w') as f:
    np.savetxt(f, c2w_matrix, fmt='%f')
