DEVICE AND METHOD FOR RECORDING DISTANCE IMAGES

摘要

Device (1) for recording spacer images comprises an evaluation unit which determines extreme values of the rise in the correlation function and determines the distances from differently spaced object regions. An independent claim is also included for a method for recording spacer images using the above device. Preferred Features: The duration of the sent light pulse (3) is not more than the time required for returning a defined distance difference. The evaluation unit determines the position of the extreme values of the rise based on a difference function of the correlation function.
