摘要
介绍的是智能相机的实时视频采集模块的嵌入式结构,可实现实时监控。嵌入式结构用赛灵思ML-507平台来进行开发。平台包含Virtex-5 FXT FPGA设备,FPGA结构中内嵌Power PC440处理器,旋转变焦(PTZ)摄像机和VGA监视器与该平台连接。接口使用板上VGA输入视频编解码器和DVI发射器芯片。芯片的控制寄存器用嵌入式Power PC440处理器配置。应用软件用C语言编写。完成了视频的采集、传输、显示,分辨率为640像素×480像素。连接与处理能力高,消耗的FPGA资源占18%,剩下的FPGA资源足够实现视频处理应用的开发。
Presenting an embedded architecture for realtime video acquisition module,realtime monitoring of a smart camera is realized. The Xilinx ML-507 platform has been used to develop the proposed embedded architecture. The platform contains a Virtex-5 FX FPGA device having PowerPC 440 processor embedded in the FPGA fabric itself. A Pan-Tilt-Zoom（PTZ）camera and a VGA monitor have been interfaced with the platform. This interfacing uses on-board VGA input video codec and DVI transmitter chips. The control registers of these chips are configured using the embedded PowerPC 440 processor. The application software is written in C language. It completes the acquisition,transmission,display whose resolution is 640 pixel×480 pixel of video. Its connecting and processing capability is high,FPGA resource consumption accounts for 18%,so the rest of the FPGA resources is sufficient for the development of video processing applications.
