Title Design of digital video capture card based on link Camera
Abstract
Firstly the video acquisition card of the historical background and trend are analyzed and summarized, carries on the introduction and related to the topic of the high-speed bus, then the camera link and video capture card are introduced in this paper, after the analysis of the USB 3.0 features which USB3.0 with its powerful performance won had widely spread. Finally, a digital video capture card scheme based on link Camera which can realize real-time collection, transmission and preservation is proposed and designed.
This paper is to study the high speed transmission of USB3.0, mainly aiming at the problem of USB3.0 high speed bus in data transmission. The hardware design of the digital video capture card based on link Camera mainly includes two parts: one is the video signal acquisition circuit; the one is the USB3.0 bus interface circuit. The use of MFC in the VS foundation class library to generate user program framework, and then add the required functionality.
To sum up, we have completed the design of digital video capture card based on link Camera, which provides a kind of options for image acquisition, transmission and storage. In addition, because of the flexibility of this kind of video capture card, it can be used in various types of video image collection.
Key words: USB3.0; camera link; digital video capture card; MFC
