Abstract
System and methods are provided for a non-coherent point tracking process that allows unknown camera motion to be estimated. One or more edges can be identified in images captured by a camera when shooting a scene. For each of the identified edge in the images, at least one tracking object can be placed arbitrarily on the edge. The positions of tracking objects in the images can then be used to estimate a camera motion. In some embodiments, two tracking objects can be placed arbitrarily on the edge to represent the edge and move along the edge arbitrarily from image to image where the edge appears. Multiple of such edges can be identified in the images and camera motions in multiple directions can be estimated based on the identified edges and combined to obtain a combined camera motion indicating the camera's movement in a 3D space when shooting the scene.
