摘要
本文介绍了一种数字化仪上图纸和数字化仪之间坐标转换的新方法。这种方法利用输入图纸上任意三个已知点（非共线）坐标，建立起图纸坐标与数字化仪坐标之间的联系，为在数字化仪上进行数据采集提供了方便。本文所提供的方法和公式，已编制计算机程序，得到了可靠的验证。
This paper presents a new method for the coordinate conversion between the picture and digitizer.The connection of the picture coordinate and digitacr coordinate could be obtained through inputting the coordinates of any three known points (nonlinear points),it is a convenient way for data acquisition in digitiger. The composed computer program been tested and verified relially.
