SIGNAL PROCESSING METHOD AND DEVICE IMPLEMENTED BY HARDWARE LOGIC FOR THE HIGH SPEED OPTICAL TRIANGULATION MEASUREMENT

摘要

PURPOSE: A signal processing method and device implemented by hardware logic for the high speed optical triangulation measurement are provided to be capable of easily and quickly processing signals of a fast two-dimensional image detector. CONSTITUTION: An image signal of a subject for photography is detected by using an image detector. Center pixel position data of irradiated linear beam are obtained by processing image signals of one frame. At this time, the frame is made of pixels detected from the image detector. The center pixel position data are transmitted to a display panel or a computer monitor per frame unit. At this time, the center pixel position data are obtained without time delay by processing image signals in real time as soon as the image detector obtains two-dimensional image signals of the subject for photography.
