摘　　要：针对金属高温塑性变形工艺特点,研发一套基于机器视觉的金属成形加工温度测量系统,系统由工业摄像头和微计算机集成,通过摄像头进行图像采集和识别处理,实现工件温度即时的非接触式测量,且能获得工件测量区域的温度分布以及工件外形轮廓形状尺寸的变化,有利于对工件成形过程及成形温度进行实时的测量和控制,对高温成形加工工艺过程的测量控制具有较大现实意义。Aiming at the process characteristics of metal forming at high temperature, the temperature measurement system for workpiece is developed based on infrared camera. The system consists of industrial camera and micro computer. Real time noncontact temperature measurement of workpieee is carried out through the camera image acquisition and recognition, and the temperature distributions in workpiece and the figuration size changes of workpiece are obtained as well. It is useful to detect and control workpiece temperature in hot metal forming.
