Problems solved by technology

However, when the surface texture features of the object to be tested are less or there are many repeated textures, the accuracy of binocular matching will be greatly reduced.
In addition, traditional binocular vision can only obtain three-dimensional information of a certain angle of the object to be measured, but cannot realize three-dimensional imaging for all angles; the existing technology has not yet solved this problem

Abstract

The invention discloses a 360-degree three-dimensional imaging projection device. The 360-degree three-dimensional imaging projection device comprises a rotating platform for placing an object to be measured, a surface projector for projecting coordinate fixed points, a left camera, a right camera and an information processing control module; the left camera and the right camera are used for obtaining image information, and the information processing control module receives information of the surface projector, the left camera and the right camera to solve three-dimensional information of a unit view angle; the surface projector is arranged between the left camera and the right camera. Through speckle patterns and a mark point array with ruleless projection, the accuracy degree of binocular matching is improved, meanwhile, a rotating platform is additionally arranged, and 360-degree three-dimensional imaging is achieved.

Description

technical field [0001] A projection device, especially a three-dimensional imaging projection device. Background technique [0002] Three-dimensional imaging plays an important role in many fields, such as machine vision, industrial inspection, profiling and other fields. Among them, binocular vision is widely used in 3D imaging because of its simple structure and principle. [0003] The traditional binocular vision method generally only has two cameras. The system first performs binocular positioning, and then performs calibration and matching operations to obtain a disparity map, thereby reconstructing the 3D model of the object. However, when the surface texture features of the object to be tested are less or there are more repetitive textures, the accuracy of binocular matching will be greatly reduced. In addition, traditional binocular vision can only obtain three-dimensional information of a certain angle of the object to be measured, but cannot realize three-dimensi...
