摘要
依据介入诊疗环境对图像采集系统的小巧性、低功耗性和实时性要求,提出了一种基于ARM处理器的图像采集方案。系统以OMNIVI-SION公司OV9650为摄像头模组,以SAMSUNG公司的S3C2440 ARM芯片为处理器,两者通过ARM芯片上的摄像头接口(CAMIF)无缝连接,实现图像数据采集,并且通过串行外设接口(SPI)与单片射频nRF24L01模块连接,实现了图像数据无线传输。
Taking into account the interventional environment,the image acquisition（IMAQ） system may be desired to be smart and low power loss and real-time capability,so a new IMAQ project was designed,Samsung S3C2440A ARM chip was used as system＇s processor and Omnivision OV9650 was used as system＇s camera which could connect the ARM chip by camera interface,in the last,the system send the image datum to PC by nRF24L01 wireless module.
