Abstract

The invention discloses an optical system for unmanned aerial vehicle imaging. The optical system comprises a body, and imaging equipment borne on the body, wherein the imaging equipment comprises a shell and a lens; a controller is arranged in the body; a processor and a storage device are arranged in the shell; and an image sensor is arranged on the lens. The optical system is characterized in that the image sensor and the storage device are in communication connection with the processor or the controller; the lens is a fish-eye lens and is composed of a first lens, a second lens, a third lens, a fourth lens, a fifth lens and a sixth lens; and the structural composition of the fish-eye lens can realize miniaturization. In addition, since each lens is a glass spherical lens, ratio correction can be easily realized. The lens is applicable to different temperature occasions.

Description

technical field [0001] The invention relates to an optical system, in particular to an imaging optical system for a drone. Background technique [0002] In recent years, UAV technology has developed rapidly. Among the uses of UAVs, taking pictures and videos is one of its main uses. The UAVs used for aerial photography are all equipped with movable connection pan-tilts, and the pan-tilts are generally equipped with driving equipment, which drives the imaging equipment, so that the imaging equipment can shoot scenes from different angles. With the development of optical lens technology, although the structural form of the fisheye lens has been continuously improved, the basic structure has not changed, mainly including the front group lens and the rear group lens. The front group lens is a meniscus with a large negative power. Shaped lens group is used to realize the optical performance with a viewing angle greater than or equal to 180°, and the rear group lens is a lens gro...
