Abstract

The invention discloses a three-dimensional (3D) camera and a method of stereo image obtaining and belongs to the field of image acquisition. The 3D camera and the method of the stereo image obtaining solve the problems of the distance between two lenses and the time difference which exist in existing 3D cameras. The 3D camera comprises a pulse laser device, a transmitting optical shaping system, a charge coupled device (CCD), a control processing circuit, an amplitude probability distribution (APD) array detector, an optical splitter, a receiving optical system and a display screen. Before a pulse is emitted by the pulse laser device, the APD array detector is shut down, and a framing picture of the CCD is displayed on the display screen. When the pulse laser device emits a laser pulse to take a picture, the control processing circuit shuts down the CCD so that a picture can not be found by the CCD. The APD array detector is started, an echo pulse passes by the optical splitter and enters the APD array detector so as to determine the flying time and obtain the one-dimensional distance, the one-dimensional intensity and two-positional angle information of the image, and the stereo image is obtained after comprehensive processing. The 3D camera and the method of the stereo image obtaining are applicable to 3D image acquisition.

Description

technical field [0001] The invention relates to a 3D camera and an imaging method. Background technique [0002] At present, the main imaging method used in 3D cameras is to use two lenses to capture images at the same time, imitating the functions of the left and right eyes of people to generate stereoscopic images. However, this imaging method has very strict requirements on the opening and closing of the two lenses at the same time, and a small time difference will cause the imaging to deviate from the blur. At present, many 3D cameras are in the trial production stage, the screen resolution is not high, and the 3D photos taken need to be post-processed and viewed on specific devices, causing a lot of inconvenience. Among them, Panasonic DMC-3D1 is a mature 3D camera with a resolution of 4000×3000 and 12 million effective pixels. The imaging time deviation between the left and right lenses is within 0.001s. The difficult-to-expand lens spacing limits the longitudinal re...
