Abstract

The invention provides a double-lens panoramic imaging device. The device comprises two single-lens optical systems, wherein each single-lens optical system comprises an isosceles right-angle prism, a first negative lens element arranged in front of a side surface corresponding to a right-angle edge of the isosceles right-angle prism as well as a first positive lens element, a second positive lens element, a second negative lens element, a third positive lens element and an imaging plane which are sequentially arranged right in front of the side surface corresponding to the other right-angle edge of the isosceles right-angle prism, and the second positive lens element and the second negative lens element are glued together; hypotenuses of the isosceles right-angle prisms of the two single-lens optical systems are mutually bonded to form a double-lens panoramic imaging system. 360-degree panoramic imaging is realized by means of the two single-lens optical systems, the two isosceles right-angle prisms are bonded together, so that the whole imaging device is super-minimized, and a user can carry the double-lens panoramic imaging device conveniently.

Description

Technical field [0001] The invention relates to the technical field of optical imaging, and in particular to a dual-lens panoramic imaging device. Background technique [0002] Panoramic optical systems have been widely used in security, robot vision, navigation and military applications. For the panoramic optical system, several solutions such as single-lens, dual-lens or multi-lens are mainly used. The single-lens panoramic optical system is similar to panoramic, small size and low cost, and there is a certain market. Due to the existence of the device and the limited field of view, it cannot achieve a true 360-degree field of view panoramic system without dead angles. The dual-lens panoramic optical system adopts two super fisheye lenses to form a panoramic system, surrounds the 360-degree field of view without dead angles, and the cost is moderate, but the volume is relatively large. The multi-lens panoramic optical system uses multiple ordinary limited field of view lenses...
