Description
Technical Field
The utility model relates to a camera lens, concretely relates to high definition virtual reality camera lens that stray light energy of image plane is few, can effectively take out truest photo of high image quality, structure simple relatively, image plane.
Background
Safety is a basic pursuit of people, and after a certain economic foundation is achieved, the consciousness of people is changed, and higher-level and wider safety requirements can be pursued gradually. Compared with the insurance market more than ten years ago, most people now have insurance consciousness, and the insurance is not so hard, which is the inevitable result of social progress. The same applies to the safety of automobiles, and the problems of existing automobiles are solved firstly, and then the safety problems in various aspects are solved, from driving safety to parking safety, parking safety and the like.
With the development of the automobile industry in China, the automobile navigation market is gradually mature, consumers are pursuing safety, convenience and use more and more, according to the trend, most automobile manufacturers in China have the intention and action of taking the panoramic looking-around system as standard configuration on luxury saloon cars, and the configuration is a trend of many automobiles in the future.
The defects of the traditional technology are as follows: (1) the lens manufactured by the traditional technology can generate ghost images when being shot under strong light; (2) the lens manufactured by the traditional technology has a small aperture, and the quality of the picture shot in a dark environment is poor, so that the lens is not suitable for all-weather use; (3) the lens manufactured by the traditional technology has low strength, is used under relatively severe conditions, and is easy to damage.
The reasons for the above disadvantages are: (1) the lens of the camera is composed of a plurality of lenses, the lenses are made of materials such as glass or plastic, and if no special treatment is carried out, the surface of the lens can reflect about 5% of incident light. When strong light enters the lens, multiple reflections are generated inside each lens and the camera, so that the phenomenon that people see in actual shooting is ghost. (2) The lens is made into a large aperture and is limited by a plurality of factors, the larger the aperture is, the more complicated the lens is required for clear imaging, each lens structure has a limit aperture, the larger the aperture is, the more complicated the structure is, and the complicated structure brings a plurality of negative effects. Among them is the most influential: loss caused by multiple reflections; ② the requirement of assembly precision is very high.
