摘要
对影像测量仪示值误差原因及种类进行探讨,并就其所产生的线性误差修正介绍两种简单的修正方法——两端点连线法与最小二乘法;通过典型示例,详细阐述运用两种修正方法对仪器是否可调进行预判断的操作步骤,并比较分析两者的优劣性。
In the paper, the author discussed the reasons and category of the indication error of Video-Measurement System, and introduced two simple methods to refine the linear error： linking-both-ends method and least-squares method simultaneously, The author demonstrated to prejudge the adjust ability of the instrument with two methods and their odds in detail.
