Abstract

A system of binocular stereo vision based on the near-infrared imaging characteristics of ordinary black-and-white CCD (B/W CCD) camera is proposed to measure the three-dimensional profile of reverse engineering. In this system the infrared LED is used as the marker for the active probe tool, and the near-infrared filter is fixed on the black and white camera to simplify the background and enhance the signal-to-noise ratio of image, the compution of segmentation for the follow-up goal can be greatly reduced. The Paper details the principle and hardware components of the binocular vision system, then analyses and discusses the critical technologies of 3-D profile measurement such as camera calibration, feature extraction and three-dimensional calculation. The experimental results show that the method has many advantages, such as the great contrast images consisted of the markers and background , processing image easily, adapting the change of illumination and better precision positioning.
