In order to measure the contour of object in high temperature environment, a new mea-suring and evaluation method based on binocular stereo vision is presented. The constitute method of optical characters and the image acquiring in high temperature environment, as well as the modeling and evaluation method is introduced. The measuring data of this method was compared with CMM. The result indicated that, the measuring error of this method is less than 0. 5 mm, which satisfies the requirements of contour measuring in high temperature environment.
