摘　　要：在采用图像法对条码尺进行检定的过程中,由于一幅移动的条码尺图像数据较大,计算机无法迅速完成对它的实时处理,所以只能采取一种半自动的方式。即在条码尺的图像进入摄像机的视场后条码尺停止移动,待计算机将图像数据处理完成后再进行移动。这就需要一种定位装置,这种装置可以在条码尺进入视场后发出一个信号,此信号作用于条码尺的承载机构,使其停止运行,在计算机将条码尺数据处理完成后再将条码尺的下一幅图像移入视场。基于以上问题的分析,本文介绍了一种在采用图像法对条码尺进行检定的过程中自动定位的方法及实验验证的情况,提出一种结合了光电技术、信号处理技术以及单片机控制技术相结合的自动定位系统的解决方案。In using images process to test grade rod,the computer can not be the speedy completion of its real-time processing because of the larger image data of moving the grade rod,so it can only adopt a semi-automatic manner.That is,when the images into the camera＇s field of view,the grade rod-foot stop moving,and after the computer complete data processing,the images move again.It requires a positioning device,such device can give a signal after the grade rod enters field of view,the signal can stop the running grade rod-foot.After data processing is completed,the other images move into the field of view.Based on the above analysis of the problem, the paper introduces the law on the use of images to test the grade rod.In the process of automatic positioning methods and experimental verification of the situation,a solution combination of photovoltaic technology,signal processing technology,and SCM control technology is introduced.
