| Abstract: | Aiming at the large amount of data, strict real-time and synchronization requirements of binocular video transmission, architecture of a binocular stereo video acquisition and display system with the core of SOPC(System on a Programmable Chip) technology was introduced and implemented in this paper. The system with the Hardware-Software Co-design technology integrates video capture controller, video storage controller and video transmission controller as a data transfer fast channel in SOPC, moreover, develops upper computer software with OpenCV. The result indicates that this design method can ensure the binocular video synchronization data acquisition and real-time data transmission, meanwhile greatly enhances the integration of the system, and reduce the complexity of the design, with well designed and highly practical |
