Catadioptric ultra-wide-angle imaging system

Abstract

The invention provides a catadioptric ultra-wide-angle imaging system comprising a camera system, a circuit system, and a mechanical system. The camera system, the circuit system, and the mechanical system are connected mutually. The camera system consists of a catadioptric lens group, a relay lens group and an image surface; the relay lens group and the catadioptric lens group are arranged coaxially; and a catadioptric first lens and a catadioptric second lens are connected by a connecting surface. With the system, ultra-wide-angle view finding can be realized. Because the catadioptric lens group employs the lens group, bearing of the large vertical view field and the large relative aperture can be realized. Moreover, the system with a compact structure can be installed conveniently.

Description

Technical field [0001] The invention relates to the technical field of optical system and device design, in particular to a catadioptric ultra-wide-angle imaging system. Background technique [0002] At present, video surveillance systems have been widely used in various fields. Cars, aircrafts, and submarines are gradually equipped with video surveillance systems. However, due to lens limitations, traditional cameras have a very limited field of view. In order to obtain a large field of view, often It is necessary to add multiple sensors. As a result, the cost has increased a lot. Moreover, in order to merge the images acquired by multiple sensors into a panoramic image, multiple stitching is required, which is complicated and time-consuming, and often cannot achieve the effect of real-time monitoring, making it useful Greatly discounted. [0003] Therefore, it is imperative to develop a panoramic lens that can overcome the above shortcomings. The existing panoramic lens usuall...

[0002] At present, video surveillance systems have been widely used in various fields. Cars, aircraft, and submarines are gradually equipped with video surveillance systems. However, traditional cameras have a very limited field of view due to lens constraints. In order to obtain a large field of view, often more sensors

As a result, the cost increases a lot. Furthermore, in order to fuse the images acquired by multiple sensors into a panoramic image, multiple splicing is required, which is complex and time-consuming, and often cannot achieve the effect of real-time monitoring, which makes its function Big discount
