摘　　要：为解决短焦距大视场红外经纬仪红外数字图像中因为实际生产过程中光学、机械、装调等因素带入的目标点成像位置误差,本文中采用了分区处理的思想,将成像靶面分为多个区,对每一个区域进行线性最小二乘处理得到所需要的参数,并将这些参数用于后续的计算,实验数据表明该方法可以显著提高全视场测角精度。In order to solve the imaging position error of the short focal length wide field of view infrared theodolite, which is caused by optical, mechanical, alignment and other factors in the actual production process, this article used the idea of partition processing that the image is divided into multiple zones, and then least squares linear processing is performed in each zone. We can obtain the desired fit parameters, which can be used to validate the calculation on the back of the validation data. Results of the experiment show that this method can improve the full-field measurement accuracy.
