Abstract:
A method for fixating a camera, mounted on a motorized mount, on a target point comprising the steps of:a) receiving a plurality of images representative of a scene; b) selecting, within the plurality of images, a first display reference image containing the target point at a first coordinate location; c) estimating, in a current image within the plurality of images, a transformation that maps the current image to the first display reference image; d) estimating a second coordinate location of the target point in the current image using the transformation; e) computing an image slip between the target point in the current image and the target point in the first display reference image; f) converting the image slip into an angular correction for fixating the camera; and g) implementing the angular correction by using closed-loop control with the motorized mount.
