Abstract

The invention discloses a distortionless high-resolution large-viewing angle unmanned aerial vehicle lens optical system, which comprises a lens front group and a lens rear group arranged sequentially along a light incidence direction. A diaphragm is arranged between the lens front group and the lens rear group; the lens front group comprises a first lens, a second lens, a third lens and a fourth lens arranged sequentially along the light incidence direction, and the first lens, the second lens, the third lens and the fourth lens are respectively a meniscus negative lens, a meniscus negative lens, a meniscus negative lens, and a biconvex positive lens; and the lens rear group comprises a fifth lens, a sixth lens and a seventh lens arranged sequentially along the light incidence direction, and the fifth lens, the sixth lens and the seventh lens are respectively a biconvex positive lens, a meniscus negative lens and a biconvex positive lens. The distortionless high-resolution large-viewing angle unmanned aerial vehicle lens optical system has the advantages that the visual angle is 100 DEG, the distortion is less than 3%, and the resolution can reach 12 million-pixel.

Description

technical field

[0001] The invention relates to an optical imaging system, in particular to an undistorted, high-resolution, large-viewing-angle UAV lens optical system. Background technique

[0002] With the improvement of UAV technology, the scope of application of UAV aerial photography is more and more extensive. The general camera equipment used by UAVs, the aerial photography system can only record images in a certain direction at the same time, and the scope of aerial photography is limited. , The image resolution is not high during aerial photography, resulting in unclear images. At the same time, the distortion of the aerial photography lens is very large, resulting in image distortion, which cannot meet the expected requirements. Contents of the invention

[0003] The purpose of the present invention is to provide an undistorted high-resolution large viewing angle drone lens optical system to overcome the deficiencies in the prior art.

[0004] To achieve the ab...
