Acquisition system and method for stereoscopic video

Abstract

The invention discloses an acquisition system and an acquisition method for a stereoscopic video. The system comprises acquisition equipment, a microcontroller, an acquisition server and stereoscopic display equipment, wherein the acquisition equipment comprises a plurality of two-dimensional (2D) cameras and a plurality of altitude regulation devices; a 2D camera is opposite to each altitude regulation device; the 2D cameras are linearly arranged, and are used for shooting planar video images; the microcontroller is connected with the acquisition equipment through a general purpose input and output port of each 2D camera, and is used for transmitting a pulse signal to the 2D cameras to control the 2D cameras to synchronously shoot the planar video images with preset frame frequency; the acquisition server is connected with the acquisition equipment through a data port of each 2D camera, and is used for acquiring the planar video images shot by the 2D cameras, geometrically calibrating the 2D cameras, and performing real-time geometrical correction and stereoscopic image synthesis on the planar video images shot by the 2D cameras; and the stereoscopic display equipment is used for receiving and stereoscopically displaying a stereoscopic image synthesized by the acquisition server. The system has real-time data acquisition capability, high flexibility and good stereoscopic perception effects.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a system and method for collecting stereoscopic video. Background technique [0002] Stereoscopic video is a new way to describe the three-dimensional world. It not only contains the surface information about the scene in traditional 2D video, but also contains three-dimensional (stereo) information related to the specific location of the scene. Compared with traditional 2D video, stereoscopic video is a more effective and realistic way of expression, and it is gradually applied to many aspects such as entertainment advertising, education and medical treatment. In recent decades, the maturity of display technology has created conditions for the development of the three-dimensional industry, but the lack of three-dimensional film sources has become a bottleneck for the further development of the three-dimensional industry. [0003] As an important way to obtain stereoscop...

Problems solved by technology

[0005] After analyzing the existing technology, it is found that the existing technology has the following problems: (1) In order to better collect stereoscopic video, it is usually necessary to manually adjust the attitudes such as the height, rotation angle and distance of the 2D camera, which helps To achieve a better stereo perception effect, while the existing binocular or multi-eye acquisition systems either integrate 2D cameras into one device, or can only complete the adjustment of individual dimensions of the camera, which is less flexible

(2) Multi-objective systems at home and abroad often need to connect multiple acquisition servers, and the communication between servers is cumbersome and time-consuming, and the captured video sequences are geometrically corrected offline
