Embodiment Construction

[0021] The present invention will be described in further detail below in conjunction with the accompanying drawings. The following examples are helpful to the understanding of the present invention and are better application examples, but should not be regarded as a limitation of the present invention.

[0022] Such as figure 1 As shown, the present invention is an internal reflection catadioptric panoramic imaging lens. The catadioptric mirror group and the relay mirror group are arranged in sequence; wherein, the catadioptric mirror group has a coaxially arranged catadioptric first lens 21 and a catadioptric second lens arranged in sequence along the direction from the catadioptric mirror group to the relay mirror group 22. The catadioptric first lens 21 and the catadioptric second lens 22 are connected through a connecting surface. The relay lens group consists of 8 lenses.

[0023] The catadioptric first lens 21 has a first refraction surface 12 and a second internal re...

Abstract

The invention provides an internal reflection type catadioptric panoramic imaging lens. The internal reflection type catadioptric panoramic imaging lens comprises a catadioptric mirror group and a relay mirror group which are arranged in sequence. The catadioptric mirror group includes a first catadioptric lens and a second catadioptric lens which are arranged coaxially and arranged sequentially along a direction from the catadioptric mirror group to the relay mirror group, and the first catadioptric lens and the second catadioptric lens are connected by a connecting surface. Full-view ultra-wide-angle imaging is realized. An appropriate angle magnification is provided to expand the field of view. The catadioptric mirror group is a lens group, and can bear greater vertical field of view and relative aperture. The field of view and the aperture of the lens are large. The long after-work distance ensures the installation space of other parts. Moreover, the lens has the effects of compact structure, small size, and easy installation.

Description

technical field [0001] The invention relates to the technical field of optical system and device design, in particular to an internal reflection catadioptric panoramic imaging lens. Background technique [0002] At present, the commonly used small fisheye lens has poor imaging quality, and the fisheye lens with better imaging has complex structure and manufacturing process, larger volume and heavier weight, so fisheye lens is not suitable for 360° panoramic monitoring system. To complete 360° panoramic monitoring, it is usually necessary to install multiple lenses with a large field of view to work together, or to rotate and tilt the imaging system to be able to complete imaging within a predetermined range. The multi-lens coordination method brings about an increase in installation requirements and costs, and the rotating and tilting device is easy to cause daily wear and tear. And when it is necessary to observe panoramic images, it is necessary to switch screens and angl...
