摘　　要：介绍一种可用于指针式仪表的自动检定系统 ,应用计算机视觉技术实现仪表读数的自动判读 ,提高了判读精度 ,所得结果的最大不确定度远小于人眼视觉所得结果的最大不确定度。An automatic calibration system based on calibrating measurements that have analog interfaces is presented in this paper. The computer vision technology is used to determine the instrument reading automatically with the results of improved reading accuracy. Results show that it can do better than human vision.
