Aspheric catadioptric panoramic imaging lens

Abstract

The invention provides an aspheric catadioptric panoramic imaging lens including a catadioptric lens group, a variable diaphragm, and a relay lens group that are successively arranged, the catadioptric lens group is provided with a catadioptric first lens and a catadioptric second lens that are coaxially arranged and successively arranged along the direction from the catadioptric lens group to the relay lens group, and the catadioptric first lens and the catadioptric second lens are connected through a connecting surface. The aspheric catadioptric panoramic imaging lens realizes the full-visual-angle super-wide-angle high definition imaging, and provides proper angle amplification multiplying power to enlarge the visual field; and the catadioptric lens group adopts a lens group, can bear larger vertical visual field and the relative aperture, and has the effects of compact structure, small size, and convenient installation.

Description

technical field [0001] The invention relates to the technical field of optical system and device design, in particular to an aspheric catadioptric panoramic imaging lens. Background technique [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 It is necessary to add multiple 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. [0003] Therefore, it is imperative to develop a panoramic lens that can overcome the above-mentioned shortcomings. Existing panorama lens ...
