Problems solved by technology

[0002] Most of the existing optical imaging systems for UAV aerial photography have the disadvantages of large volume, small field of view, low resolution, poor image quality, and less information acquisition.
For example, Chinese patents with patent numbers 201020555002.4 and 201210229615.2 disclose a lens with a long overall length and a large volume, resulting in high cost when installed on a drone, and the shooting frame is small and the image quality is poor.

Embodiment Construction

[0039] The present invention is described in detail below in conjunction with accompanying drawing:

[0040] like figure 1 As shown, a high image quality optical imaging lens for unmanned aerial photography of the present invention includes a front lens group 1, an aperture stop 2, a rear lens group 3, an optical filter 4 and an image acquisition lens in sequence from the object side to the image side Element 5. The aperture stop 2 is located in the middle of the lens, and is used to control the aperture of light transmission, so that the overall imaging picture is uniform and has high brightness. The rear lens group 3 is composed of four lenses, which are mainly used to reduce imaging aberrations and improve image quality; the filter 4 described in the embodiment of the present invention adopts an IR filter, and the image acquisition element 5 is a CMOS photosensitive chip. It enters the image acquisition element 5 from the filter 4, the filter 4 has a certain protective ef...

Abstract

The invention discloses a high-image-quality optical imaging lens for unmanned plane aerial photography. The imaging lens includes a front lens set and a rear lens set, an aperture diaphragm is arranged between the front lens set and the rear lens set, both of the front lens set and the rear lens set are non-spherical lenses, and through the optimization of the parameters of the lenses in each of the front lens set and the rear lens set, the imaging lens has the characteristics of high image quality, large view field, high resolution, less distortion, small size, large shooting frame, clear obtained image, and low cost, and can be applied to an unmanned plane aerial photography optical imaging system.

Description

【Technical field】 [0001] The invention relates to an optical imaging lens, in particular to an optical imaging lens with high image quality for aerial photography of unmanned aerial vehicles. 【Background technique】 [0002] Most of the existing optical imaging systems for UAV aerial photography have the disadvantages of large volume, small field of view, low resolution, poor image quality, and less information acquisition. For example, the Chinese patents No. 201020555002.4 and 201210229615.2 disclose a lens with a longer overall length and a larger volume, which results in higher cost when installed on a drone, and the shooting frame is small and the image quality is poor. [0003] The present invention studies and proposes aiming at the deficiencies in the prior art. 【Content of invention】 [0004] The present invention overcomes the deficiencies of the prior art, and provides a high image quality optical imaging lens for unmanned aerial photography, including a front l...
