摘要：
Apparatus and methods for tracking scanner motion with a tracking illumination emitter mounted on a scanner, the scanner including imaging apparatus that captures a sequence of images of a scanned object as the scanner moves with respect to the scanned object tracking targets installed off the scanner at positions that are fixed relative to a scanned object one or more tracking illumination sensors mounted on the scanner, the tracking illumination sensors sensing reflections of tracking illumination emitted from the tracking illumination emitter and reflected from the tracking targets as the scanner moves in the process of scanning the scanned object and one or more data processors, at least one of the data processors coupled for data communications to the tracking illumination sensors, the data processor determining, as the scanner moves, tracked positions of the scanner based upon values of the reflections.
