本文简述了用电视摄象机进行工业尺寸测量的微分法与拟合法的基本原理,同时详细的讨论了各自所能达到的精度极限。本文用实验验证了理论计算的结果,最后对二维工件测量时,如何根据工件的不同形状与位置以及光学系统的特点,提出了在测量时工件的放置应该注意的问题以及对工件拐角处如何进行处理的方法。
This paper describes the basic principles of the differential method and the fitting method of the industrial size measurement by using the TV camera. At the same time, it discusses in detail the precision limit each can achieve. In this paper, the result of theoretical calculation is validated by experiments. At last, how to place the workpiece in the measurement according to the different shape and position of the workpiece and the characteristics of the optical system when the two-dimensional workpiece is measured, and how to deal with the corner of the workpiece The way to deal with.
