High-definition wide-angle drone camera lens

Abstract

The invention discloses a high-definition wide-angle drone camera lens which comprises a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a diaphragm, a sixth lens, a seventh lens, an eighth lens, a ninth lens, a tenth lens, a light filter and an imaging device. Light rays emitted by objects pass through the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the diaphragm, the sixth lens, the seventh lens, the eighth lens, the ninth lens, the tenth lens and the light filter sequentially to be outputted. The output light rays are imaged on the imaging device. Through the first lens, the second lens, the third lens, the fourth lens, the fifth lens, the diaphragm, the sixth lens, the seventh lens, the eighth lens, the ninth lens, the tenth lens,the light filter and the imaging device, high definition is realized, purple boundaries are eliminated, and the quality of acquired images is improved.

Description

technical field [0001] The invention relates to the field of unmanned aerial vehicles, in particular to a high-definition wide-angle unmanned aerial vehicle lens. Background technique [0002] The drone market is developing rapidly, and the requirements for its components such as lenses are getting higher and higher. For example, the resolution requirements range from ordinary 1080P to 5MP high-definition, or 4K ultra-clear, close to 9MP, or even 12MP; the target area is also large, such as 1 / 2.3”; and pay more and more attention to some details, such as wide-spectrum purple fringing. [0003] When designing traditional visible light imaging lenses, the wavelengths are usually F light (486nm), d light (588nm), and C light (656nm), and the ratio is 1:1:1. Some lenses designed in this way will have a large field of view and serious purple fringing phenomenon when used. For example, if you shoot a straight and white street light pole at a long distance, you will find that the ...

Problems solved by technology

[0004] In order to solve the problem of purple fringing, the company has introduced plastic aspheric lenses for the development of lenses, which reduce the weight, simplify the structure, and the overall size is small, but its temperature characteristics are not good, and it cannot meet the temperature range of -20°C to +80°C. maintain high definition
