Claim 8:
9. The computer-implemented method of claim 7, wherein the camera calibration procedure further comprises:
determining a plurality of poses of the object in the real-world space while the camera device remains in a same pose;
receiving a plurality of images generated by the camera device, wherein the plurality of images represents a video stream that shows the object in the plurality of poses;
determining that the third pose is shown in the image;
determining a projection error between the image and a projection of the object in the third pose onto an image plane of a camera model of the camera device, wherein the camera model comprises the at least one calibration parameter;
selecting a subset of images of the plurality of images based on projection errors, wherein the subset of images is associated with a subset of poses of the plurality of poses; and
updating the camera model based on the subset of images and the subset of poses.
