摘要

分析了航空红外相机的结构特点

论证了装调该类相机的关键技术。提出一种针对单相机镜头的装调和验证方法。该方法基于经纬仪测试探测器的线阵方向和视轴方向对相机进行粗调

结合质心亚像元定位算法对相机进行精调。提出了基于大口径平行光管和高精度可控转台覆盖所有镜头完成一次性装调的方案

解决了多个视轴相机组视轴高精度一致性装调的问题。实验表明:提出的方法满足航空红外相机的高精度、小公差的装调要求。单相机视轴与光轴夹角、多角度各组相机之间的视轴夹角的实际装调精度达到0.052 pixel

比常规方法单像元的装调精度提高近20倍。提出的方法为航空红外相机的高精度装调提供了一种精确可行的途径

并可应用于结构类似的航天遥感器的装调。

Abstract

The structural characteristics of aerial infrared cameras were analyzed

and the key technologies of alignment of this type of cameras were validated. A method for adjustment and validation of a single camera was proposed. The method adjusted the camera coarsely based on measuring the line array direction and optical axis direction of a detector by a theodolite

and adjusted the camera finely by combining with the sub-pixel subdivision location algorithm. A scheme to complete a one-time adjustment by covering all lenses was proposed based on a large diameter parallel light pipe and a high precision controlled turntable

by which the grouped alignment and validation for the aerial infrared camera were implemented. The simulation results show that the method meets the demands of aerial infrared camera for high accuracy alignment and small tolerances. The adjustment precision of the angle among the boresights of multi-angle camera has reached 0.57 pixel

which is about 20 times that of the traditional methods. The proposed method provides a practical and feasible way to adjust precisely aerial infrared cameras and can be used in adjustment for other aerial sensors with similar structures.
