摘要
开发了一套具有本地编译能力的低成本模块化嵌入式计算机视觉实验系统"CV-Innovator"。硬件上,该系统的嵌入式处理器采用全志A20双核ARM Cortex-A7 So C(System on Chip,片上系统),通过彩色CMOS摄像头OV7670采集实时图像,18 cm TFT-LCD显示屏和USB键盘鼠标提供友好的人机交互。软件上,为"CV-Innovator"构建了嵌入式Linux操作系统,可在嵌入式Linux环境下开发和运行基于Open CV和Qt的计算机视觉应用程序。进行了样机试制,并设计了一个人脸检测示例应用程序,其结果表明"CV-Innovator"能实现预期功能,可应用于我国高校计算机、电子信息及自动化等相关专业的本科实验教学。
This paper develops a native buildable low-cost modular embedded computer vision experimental system named ＂CV-Innovator＂. In the hardware aspect,this experimental system was composed as follows： an ARM Cortex-A7dual-core So C Allwinner A20 used as embedded processor; an OV7670 CMOS digital camera module collects real-time image; a 7-inch TFT-LCD monitor as well as a set of keyboard and mouse with USB port provide friendly humanmachine interaction. In the software aspect,we build an embedded Linux OS for ＂CV-Innovator＂,so the Open CV and Qt based computer vision application program can be developed and run under the embedded Linux. When a prototype was made,we designed a face detection example application program. The example results validated the effectiveness of＂CV-Innovator＂,and system can be used in practice teaching of the computer science,electronic information,automation,etc.
