Abstract:
1. A computer based method for estimating an orientation of a target using depth image data, the method comprising the steps of: receiving a feed of depth images capturing a target, the depth images including pixel depth information; determining a correlation between each image and a corresponding orientation measure for a set of images in the feed, the set of images representative of a set of target orientations, and the correlation providing a match between an image and a corresponding orientation measure representative of the orientation of the target captured in the image; wherein determining the correlation comprises: storing the set of depth images of the target and the correlation; and comparing, based in appearance, a current depth image of the target with the depth images in the set of depth images to determine, based on the correlation, a corresponding orientation measure indicative of a current orientation of the target as captured in the current depth image.
