The invention discloses a device for light projection and image acquisition in three-dimensional real-time photography and an acquisition method thereof and belongs to the field of three-dimensional photographic image acquisition. In the device of the invention, a data acquisition device positioned at the upper part of a platform comprises a camera, a first imaging reflector, a second imaging reflector and a rectangular prism; a light projection device comprises a projection device, a first projection reflector and a second projection reflector; the projection device is fixed at the upper part of a lower platform; and the device further comprises a synchronizer connecting the camera and the projection device. The acquisition method of the invention comprises the following steps: adjusting the angle and the distance of the first imaging reflector and the second imaging reflector relative to the two rectangular surfaces of the rectangular prism as well as the angle and the distance between the first projection reflector and the second projection reflector according to different targets to be acquired; and finally synchronizing the camera and the projection device by the synchronizer to acquire the image. The invention realizes the simultaneous two-angle acquisition of the target image using one camera and the real-time synchronization of acquisition and projection.
Description
technical field [0001] The invention relates to a three-dimensional camera system, in particular to a device for light projection and image acquisition in three-dimensional real-time camera and an acquisition method thereof, belonging to the field of three-dimensional camera image acquisition. Background technique [0002] The 3D imaging based on the principle of triangular vision requires the information of two angles of the target in 3D calculation. In the 3D acquisition system based on active light projection, when the dual-camera captures, it is on the angle bisector of the optical axis of the dual-camera (or in the direction of a certain angle with the optical axis of the single-camera when it is collected by a single-camera) Generally, light emitted by a projection device is required, and the light path emitted by it is projected on the collection target. [0003] The method based on the binocular camera is to determine the three-dimensional information through the re...
