Optical system for acquiring three-dimensional information of surface of shot object

Abstract

The invention discloses an optical system for acquiring three-dimensional information of the surface of a shot object, which comprises an optical subsystem, the optical subsystem comprises a plurality of first optical elements and photosensitive elements which are sequentially arranged along an optical path, and a second optical element is further arranged at a preset position of the optical subsystem. Incident light reflected by a shot object sequentially passes through the first optical elements and the second optical elements along a light path and then irradiates the photosensitive element to generate a plurality of sub-images with view angle differences; the second optical element comprises at least two optical element units, and every two adjacent optical element units are arranged in parallel according to a set structure; the optical element unit has a set incident surface and an exit surface corresponding to the incident surface. The system can obtain a plurality of sub-images with view angle differences of the shot object from the internal light of the optical system, and then further processes the plurality of sub-images with view angle differences through other processing devices, so that the three-dimensional space information of the shot object can be obtained.

Description

technical field [0001] The invention relates to the technical field of photographing equipment, in particular to an optical system for acquiring three-dimensional information on the surface of an object to be photographed. Background technique [0002] The existing optical system needs to obtain three-dimensional information on the surface of the object to be photographed. If the object to be photographed is moving, laser + ordinary camera (or video camera), radar + ordinary camera (or video camera), infrared + ordinary camera (or video camera) are usually used. ), or an array composed of multiple cameras to shoot synchronously; if the object to be photographed is stationary, an ordinary camera (or video camera) is usually used to photograph the object to be photographed from multiple angles, or a light field camera is used to photograph the object to be photographed to shoot. However, regardless of the above-mentioned shooting method, more equipment needs to be used, and t...
