为了应对实时视频图像处理复杂的现场环境条件,设计了一种通用视频图像处理系统.该系统便于扩展,可同时应用于多种不同现场环境.FPGA+DSP 架构由于同时吸取了具有优秀运算性能的 DSP 芯片以及具有高实时性的 FP-GA 芯片的优点而在实时图像处理领域中得到了广泛的应用,而 Compact-PCI 总线由于其与工业控制计算机有标准的接口而具有良好的可扩展性,通过对二者的有机结合设计了基于 Compact-PCI 总线的 FPGA+DSP 架构的通用视频图像处理系统.硬件实验表明,系统可对320×256~1024×1024分辨率,8~14 bits,最高帧频100 Hz 的视频图像进行实时采集与处理,并通过 cPCI 总线实现实时控制,取得了良好的效果,表明系统可以应用于红外及可见等复杂环境中,实时性很高,处理效果好,提高了系统的应用范围.为视频信号采集处理提供了一种新的可靠解决方案.
In order to deal with the complicated field environmental conditions that real-time video image process systems have to confront,a general-purpose real-time video image process system is de-signed,which is extendable and can be applied to multiple field environmental conditions simultane-ously. Image process systems based on FPGA+DSP architecture are widely used in the field of image process,because the DSP processor is of high calculating performance and the FPGA is of high real-time performance,while the Compact-PCI bus is extendable because its interface with the computer is already standardized. Combining both advantages,a new general-purpose video image process system is designed based on Compact-PCI bus and FPGA + DSP architecture. Hardware experiments show that,this system can be equal to capturing and processing video images of 320 ×256 ~1 024 ×1 024 pixels,8~14 bits and maximum frequency of 100 Hz real-timely. Besides,it can also realize real-time control by means of the Compact-PCI bus,of which the result is pretty good. It indicates that this system is capable of dealing with complicated environment,such as infrared and visible scenes. It is real-time and effective. It provides a new possible solution to video image capture and process.
