基于Zynq-7000的双目相机系统硬件平台设计
|
摘要
目前,仅获取二维图像的单目相机已经不能满足日益严峻的公安视频监控工作。本文设计了一款可以为三维图像分析提供硬件平台的双目相机,采用Zynq-7000芯片作为双目相机系统解决方案。通过集成设计工具Vivado编写,添加自定义IP核(Intellectual Property core),配置各IP的端口、电平、时钟等信息,最后对工程进行综合,生成完整系统文件后导入软件开发工具包编写显示程序。系统通过OV5642双目摄像头实现两幅图像的实时采集和显示。测试结果表明,本硬件系统不仅可以显示高清、流畅的彩色视频图像,还保证了系统的高性能、低功耗。
At present,the monocular camera that only acquire two-dimensional images is no longer able to satisfy the increasingly severe public security video surveillance work requirements.A binocular camera that could provide a hardware platform for 3 Dimage analysis is designed.The Zynq-7000 chip is used as a binocular camera system solution.We program and add custom IP cores to configure the port,electrical level,clock and other information of each IP,and synthesize the project,then import the software development kit after generating a complete system to write the display program by integrated design tool Vivado.The system will capture and display two real-time images through the OV5642 binocular camera.The test results show that the hardware system can not only display high-definition,smooth images,but also ensure high performance and low power consumption of the system.
