Systems and methods to fit an image of an inventory part are described. In one aspect, a method includes receiving images of items over a computer network from a server, capturing a live video image of an object using a camera, playing the live video of the object on an electronic display, and continually refitting an image of a first item from the received images of items to the object as the object changes perspective in the video by applying an affine transformation to the image of the first item.
