Large-view-field lens for intelligent camera

Abstract

The invention belongs to the technical field of intelligent cameras, and discloses a large-field-of-view lens for an intelligent camera. The large-field-of-view lens comprises a first lens barrel, wherein a second lens barrel is movably connected to one side of the first lens barrel, a connecting barrel is movably connected to one side, far away from the first lens barrel, of the second lens barrel, the side, away from the second lens barrel, of the connecting barrel is movably connected with a third lens barrel, a plano-convex lens and a biconvex lens are arranged in the first lens barrel, aPingham prism is arranged in the second lens barrel, a concave-convex lens is arranged in the third lens barrel, and a lens barrel sleeve is fixedly installed on the outer side wall, away from the second lens barrel, of the first lens barrel. According to the invention, through movable connection of first external threads and first internal threads and movable connection of second external threadsand second internal threads, the relative distance between the first lens barrel and the second lens barrel and the relative distance between the second lens barrel and the connecting barrel can be adjusted, so that the focal length of the large-field-of-view lens for the intelligent camera can be adjusted conveniently and rapidly.

Description

technical field [0001] The invention belongs to the technical field of smart cameras, and in particular relates to a large field of view lens for a smart camera. Background technique [0002] A smart camera is an intelligent derivative of a camera. A camera is a device that uses the principle of optical imaging to form an image and uses a film to record the image. It is an optical device for photography. In modern social life, there are many devices that can record images, with the characteristics of light perception adjustment, automatic photo taking and automatic exposure compensation. [0003] Due to the lack of adjustment equipment for the lens barrel of the existing large field of view lens for smart cameras, the operation of adjusting the focal length of the lens barrel for the large field of view lens for smart cameras is relatively complicated and not convenient enough, which is not conducive to the use and promotion of the device.
