Abstract

The utility model relates to the technical field of camera lenses, and especially relates to an unmanned aerial vehicle camera lens of small distortion of a big target surface. The unmanned aerial vehicle camera lens of the small distortion of the big target surface comprises a lens cone, wherein the front side of the the lens cone is opposite to a test chart card, and the rear side of the lens cone is opposite to a shooting die set; a hollow chamber is formed in the lens cone; a first lens element, a second lens element, a third lens element, a fourth lens element, a fifth lens element, a sixth lens element, a seventh lens element, an eighth lens element, a ninth lens element, and a tenth lens element are sequentially arranged in the hollow chamber from front side to the rear side along an optical axis; and the rear side of the lens cone is also provided with a locking ring used for locking the tenth lens in the hollow chamber. The unmanned aerial vehicle camera lens of the small distortion of big target surface is of an 8G2P (8 pieces of glass lens + 2 pieces of plastic lens) glass-plastic mixed structure; the resolution ratio is high; the imaging effect of 2000 ten thousand pixels is reached; and the shot picture is clear, thereby facilitating accurate analysis and judgment of an image in later stage.

Description

【Technical field】 [0001] The present application relates to the field of lens technology, in particular to a UAV camera lens with large target surface and small distortion. 【Background technique】 [0002] In recent years, the UAV industry has developed rapidly. UAVs are usually used for aerial photography, reconnaissance, surveillance, communication, anti-submarine, electronic interference and other occasions. Therefore, UAVs have become an important tool for civil and military industries. [0003] At present, the camera lenses used on drones generally have the problems of large deformation of imaging images, low resolution, and low definition of captured images, which is not conducive to accurate analysis and judgment of later images, and seriously affects the imaging quality of drone camera lenses. At the same time, it has also become some important factors restricting the development of drones, especially because the sensor target surface of the camera lens is small, whic...
