Abstract
An image of the object remains in the field of view of the camera, thereby generating a continuously changing image signal. The images are captured and digitized in a continual sequence S of discrete images of the scenes at a respective sequence T of points in time. During this capture sequence, a first plurality of reference signals are established corresponding to a plurality of respective captured images. In this manner, a plurality of reference images are generated on-line, during movement of the object or cameras. A second plurality of detected signals corresponding to a second plurality of captured images, are individually correlated with the respective next previous reference signal of the sequence, thereby establishing a relative position of the object or camera, for each detected signal. The absolute position of the camera or object, is determined by accumulating these relative positions.
