Embodiment Construction

[0047] The first step: Fix the CCD camera on the platform, pay attention to keep the direction of each optical axis roughly parallel, and make each CCD roughly on the same straight line with roughly the same spacing; use the data cable to connect each CCD with the image capture card in the PC Connected, the cylindrical grating type or slit grating type stereo display is directly connected to the PC; connect the power cord, turn on the computer and the stereo display, install the CCD driver software, etc.

[0048] Step 2: Set the calibration template ( image 3 ) Place it at a position within 2-3 meters in front of the stereo camera, select a position in the upper left corner of the template plane, use two orthogonal straight lines as the xy axis, and establish a world coordinate system according to the right-hand rule. Adjust the focal length of each CCD to make it a clear image, and then each CCD will take an image of the calibration template once, and change the angle and positio...

Abstract

The invention designs an immediate-shooting immediate-display multi-lens digital stereoscopic system. The system consists of a stereoscopic shooting system and a stereoscopic display system jointly, and concretely comprises a plurality of CCD camera units (1), a platform (2) for fixing the CCD camera units, a bracket (3) for supporting the platform, an image acquisition card (4), a power source (5), a PC (6), a cylindrical-surface grating-type or slit-type naked-eye free stereoscopic display (7) and the like. The stereoscopic system adopts a camera calibration method to initially adjust the spatial position relation of the CCD camera units and calculate the distortion coefficients of camera lenses, corrects the geometric distortion of images according to the distortion coefficients, adopts epipolar geometry to correct trapezium distortion caused by camera layout, and then adjusts unreasonable parallax in multipath acquisition. Through the combination of the methods, the stereoscopic system can shoot not only static scenes, but also dynamic scenes, enables a shooting process to be simpler, convenient and flexible, and can realize shooting-displaying synchronization.

Description

1. Technical Field [0001] The invention belongs to the field of computer multimedia technology, in particular to a real-shot real-display multi-lens digital stereo system. 2. Background technology [0002] As we all know, the real world is a true three-dimensional world, and most of the existing display devices can only display two-dimensional information, and cannot give people a sense of depth. In order to make the displayed scenes and objects have a sense of depth (that is, 3D), people have tried various aspects. The research of 3D display technology has experienced more than ten years of development, and has achieved very fruitful results, from various handheld observers, 3D stereo glasses, helmet-mounted displays, to the latest 3D displays that do not require glasses, etc. . The 3D display system is based on the principle of stereo imaging. The real world is a three-dimensional world. It provides two images with parallax for the human eyes. When reflected in the eyes, the pa...
