摘　　要：针对高温环境下的物体外形轮廓测量,给出了一种基于立体视觉的动态测量与评定方法。包括实现轮廓度测量的光学特征构建方法、基于光谱原理的高温图像采集方法、理论轮廓数据建模及评价方法。通过试验将该方法的测量结果与三坐标测量机的测量结果进行了分析和比较。结果证明,该方法的轮廓度测量误差小于0.5mm,可以满足高温环境下物体外形轮廓检测的要求。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.
