【摘要】：视频是人们获取信息的一种重要手段。为了获得视频数据，就要进行图像数据采集。作为视频采集系统的核心，视频采集卡的设计十分重要。其中基于PCI总线的视频采集卡以其优越的性能成为市场主流产品。本论文中的多路视频采集系统就是在基于PCI总线技术的视频采集卡基础之上开发的，它主要包含驱动程序和应用控制软件两个部分，可以实时的将采集卡采集到的图像数据通过驱动程序传送给应用控制软件，以便于显示或者保存。根据眼动定位项目的需求，本文深入研究了PCI总线协议以及驱动和应用程序开发的相关技术知识。上层应用控制软件部分根据具体项目需求，采用多窗口显示，模块化编程理念，多线程以及动态链接库技术，实现了双路视频数据实时显示。底层驱动程序部分在对比了之前各种驱动程序编程技术的优缺点之后，选择使用DriverStudio3.2开发工具来开发采集卡驱动程序。这种方法比使用DDK开发WDM驱动程序更容易，并且易掌握，难度小，，出错少，调试过程简单。最后对整个系统进行调试，测试其工作稳定性。系统达到了设计要求，双路采集系统帧率最高达到了60fps，PCI最高传输速率达到了80MB/S。
[Abstract]:Video is an important means for people to obtain information. In order to obtain video data, we must collect image data. The design of video acquisition card is very important. The video capture card based on PCI bus has become the mainstream product of the market with its superior performance. The multi-channel video acquisition system in this paper is based on the PCI bus technology. Developed on the basis of cards, It mainly includes two parts: driver and application control software. The image data collected by the acquisition card can be transmitted to the application control software through the driver in real time, so that it can be displayed or saved easily. According to the requirements of eye positioning project, this paper deeply studies the PCI bus protocol and the related technical knowledge of driver and application development. The upper application control software part adopts multi-window display according to the specific project requirements. The concept of modular programming, multithreading and dynamic link library (DLL) technology are used to realize the real-time display of video data. The bottom driver part compares the advantages and disadvantages of the previous driver programming techniques. Choose to use DriverStudio3.2 development tools to develop card driver. This method is easier than using DDK to develop WDM driver, and easy to grasp, less difficulty, less error, simple debugging process. Finally, debug the whole system. The stability of the system is tested. The system meets the design requirements, and the frame rate of the dual-channel acquisition system reaches the maximum of 60fps PCI and the highest transmission rate is 80MB / s.
