An infinitely rotating large field of view scanning imaging system and control system

Abstract

The present invention provides an infinitely rotating large field of view scanning imaging system, which realizes the imaging system of large field of view area scanning by controlling the camera to perform infinite conical rotation, including a subsystem and an independent camera, and the subsystem controls two cameras with a mechanical structure The conical rotation realizes the scanning and imaging of the large field of view area, and the independent camera stares at the central field of view for imaging, and obtains a complete large field of view image by splicing the three fields of view. The imaging quality is high, the device is smaller, and the structure is simpler and more compact. The degree of integration is higher and the engineering practicality is better. The present invention also provides an infinitely rotating scanning imaging system with a large field of view, which has the characteristics of high imaging quality and simple structure.

Description

technical field [0001] The invention relates to the field of photoelectric detection, in particular to an infinitely rotating large field of view scanning imaging system and a control system. Background technique [0002] When capturing long-distance air targets, one method is to first use radar to detect the target, obtain the azimuth data of the target, and then use a telephoto camera to capture and image the target. However, there is a problem with this method: the measurement accuracy of the target azimuth by the radar is low, and the field of view of the telephoto camera is very small, so that the field of view of the telephoto camera cannot completely cover the possible range of the target, which affects the accurate capture of the target. [0003] Under the circumstance that the measurement accuracy of the existing radar cannot be improved, increasing the field of view of the telephoto camera becomes the solution to this problem. At present, the existing solution pro...

However, this method has a problem: the measurement accuracy of the radar to the target azimuth is low, and the field of view angle of the telephoto camera is very small, so the field of view of the telephoto camera cannot completely cover the possible range of the target, which affects the accurate capture of the target

figure 2 (a) is a schematic diagram of the subsystem. The subsystem scans the field of view by controlling the camera to perform conical rotation. The system controls the No. 1 camera to figure 2 (b) No. 1, 2, 3, and 4 sub-fields of view are exposed, No. 2 camera is exposed to No. 5, 6, 8, 9, 11, 12, 14, and 15 sub-fields of view in the picture, and No. 3 camera is exposed to the picture Sub-fields of 7, 10, 13, and 16 were exposed, and then the sub-images obtained by exposure were spliced ​​into a whole large field of view image to realize continuous scanning of the large field of view area, but the imaging quality of the target field of view was not high. The structure of the device is more complicated
