360-degree three-dimensional imaging projection device

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.
