Binocular video synchronous acquisition equipment

Abstract

The invention relates to binocular video synchronous acquisition equipment. The conventional multi-channel video acquisition module adopts a time-sharing acquisition way and cannot really realize double-channel video synchronous acquisition. The binocular video synchronous acquisition equipment comprises a clock synchronous circuit, a first video decoding circuit, a second video decoding circuit,a programmable logic device, a first memory buffer circuit and a second memory buffer circuit, wherein the first video decoding circuit is in signal connection with a first input end of the programmable logic device and the second video decoding circuit is in signal connection with a second input end of the programmable logic device; the clock synchronous circuit is in signal connection with the first video decoding circuit and the second video decoding circuit respectively and provides clock signals for the first video decoding circuit and the second video decoding circuit; and the first output end of the programmable logic device is in signal connection with the first memory buffer circuit and the second output end of the programmable logic device is in signal connection with the secondmemory buffer circuit. The binocular video synchronous acquisition equipment realizes clock synchronization of two channels of video decoding chips and seamless buffer storage of the two channels of video data.

Description

technical field [0001] The invention belongs to the technical field of computer stereo vision, and in particular relates to a binocular video synchronous acquisition device. Background technique [0002] Binocular video acquisition is the prerequisite and key technology for realizing binocular stereo vision system. The main difficulties in binocular video acquisition are: (1) clock synchronization of binocular video decoding chips; (2) seamless buffer storage of binocular video data; (3) synchronous storage of binocular video data at the pixel level. [0003] Existing multi-channel video acquisition modules usually use a time-sharing acquisition method, which cannot truly realize synchronous acquisition of two channels of video; in terms of storage and transmission, usually after completing the analog / digital sampling of video signals, the video data is directly transmitted to the host computer , even if there is data buffer storage, the circuit is relatively simple, and it...
