摘要
针对光电经纬仪短焦、大视场红外图像光学、机械、设备组装引入畸变较大的情况,借助光电经纬仪硬件平台,设计了自动打点控制、图像采集程序,并使用了分区修正靶面畸变的算法。试验表明:分区后,使用最小二乘法迭代模型系数,用于后续的精度计算,可以显著提高全视场测角精度。原有的人工打模型点时间为3.5 h,使用伺服自动控制打模型点方法后,可以在20 min内完成。
The position error of the projectile infrared image is taken in by the theodolite with short focal length and wide field and its optical mechanical and installation factor. The article gives the method of partition processing and auto servo control： the image is divided into multiple zones, the least squares method being used to calculate fit approximation parameters of every zone to validate data. The experiment results show that this method can be a substantial increase in the full-field measurement accuracy, and the process can be completed within twenty minutes.
