Background
The unmanned aerial vehicle aerial image has the advantages of high definition, large scale, small area and high behavior. The method is particularly suitable for acquiring aerial images (roads, railways, rivers, reservoirs, coastlines and the like) of the banded regions. And the unmanned plane provides a remote sensing platform which is convenient to operate and easy to transfer for aerial photography. The take-off and landing are limited by the field less, and the device can take off and land on playgrounds, roads or other broader ground, has good stability and safety, and is easy to transition. The device is small, light, low in noise, energy-saving, efficient, mobile, clear in image, light, small and intelligent, and is a prominent characteristic of unmanned aerial vehicle aerial photography.
Along with the popularization and development of unmanned aerial vehicle remote sensing technology and the application of all-glass lenses, the development of all-glass high-resolution ultra-wide-angle lenses is bound to come to a new height. The current remote sensing technology is mature day by day, the unmanned aerial vehicle field of taking photo by plane is also advancing the development of remote sensing technology continuously, and high resolution super wide angle camera is the essential sensor of remote sensing technology, can collect environmental data, realizes functions such as front view, back view, look around. This results in an upgrade in the remote sensing technology to drive the high resolution lens usage up.
The disadvantages of the conventional technology are as follows:
1. the lens manufactured by the traditional technology can generate ghost images when shooting under strong light;
2. the lens manufactured by the traditional technology has smaller aperture, and the quality of the picture shot in the dark environment is poor, so that the lens is not suitable for all-weather use;
3. the lens manufactured by the traditional technology has lower strength, is used under relatively severe conditions, and is easy to damage.
The reasons for the above drawbacks are as follows:
1. the lens of the camera is composed of a plurality of lenses, and the lenses are made of materials such as glass or plastic, and if no special treatment is carried out, the surface of the lens reflects about 5% of incident light. When strong light enters the lens, multiple reflections are generated inside each lens and the camera, and the reflection is performed on the surface of the metal sub-component, so that the phenomenon seen by people in actual shooting is ghost.
2. Making the lens into a large aperture is limited by a plurality of factors, the larger the aperture, the more complex the lens is needed for clear imaging, each lens structure has the limiting aperture, the larger the aperture is, and the complex structure brings a plurality of negative effects. Among the most influencing are: (1) the assembly accuracy requirements of the loss (2) caused by multiple reflections are very high.
3. Plastic lenses have poor environmental durability and imaging stability, and can exhibit degradation of image quality over prolonged use in extreme environments.
