Abstract

The invention relates to a catadioptric panoramic imaging system and an imaging method thereof. The optical system is sequentially provided with a front group A, a diaphragm and a rear group B from anobject side to an image side along light. The front group A comprises a reflector A-1, a crescent lens A-2 and a biconcave lens A-3 which are arranged in sequence, the rear group B comprises a biconcave lens B-1, a biconvex lens B-2 and a biconvex lens B-3 which are arranged in sequence, and the biconcave lens B-1 and the biconvex lens B-2 are connected in a sealed mode to form a gluing group. The optical system is simple in structure, reasonable in design, wide in view field range, good in image surface uniformity, good in imaging quality, and convenient to process and install.

Description

technical field [0001] The invention relates to a catadioptric panoramic imaging system and an imaging method thereof. Background technique [0002] In recent years, due to the development of application fields such as machine vision, virtual reality, robot navigation, and security monitoring, people have put forward requirements for real-time imaging of scenes in all directions in space, and at the same time, higher requirements have been put forward for the resolution of collected images. [0003] At present, the fisheye lens optical imaging system is often used to solve people's requirements for real-time imaging of scenes in all directions in space. This type of optical system compresses the field of view angle by applying a number of negative meniscus lenses in front of the system for refraction, so as to achieve a large The effect of field of view shooting. However, the number of lenses used in the fisheye lens optical system is large, resulting in high processing cos...
