Abstract:This study develops a video-rate stereo range finding circuit to obtain the depth to objects in a scene by processing video signals (R, G. B, and brightness signals) from binocular, CCD cameras. The electronic circuit implements a dynamic threshold method to decrease the affection of signal noises in characteristic points detection. where a video signal from each CCD camera is compared with multiple thresholds shifling dynamically by feeding back the previous comparison result. Several object depth measurement… Show more
