The viewpoints generated from the object coordinates cannot be strictly matched to the ones from the camera coordinates one by one. So the grasp labels at one viewpoint generated from the camera coordinates (in training) are estimated by searching the nearest viewpoints from the object coordinates, where the original labels are in.
