基于ARM嵌入式图像处理系统设计与实现

针对现在的过程检测系统的实时需求,设计出一种成本低,功能适中的图像处理采集系统.该系统以ARM7(S3C44B0X)为核心并配上外围电路实现图像处理功能,再加上多种通讯接口设计的图像传输通道,然后加入SD卡接口用于提取图像数据.最后基于uC/OS-II嵌入式操作系统设计了一种图像处理方法,在系统中实现了图像增强、图像分割和目标定位.实验表明,该系统能够很好地解决图像在线处理功能的实时问题,图像处理的准确率也满足了过程检测系统的要求,而且实现简单,成本比较低,特别适合于对功耗、体积要求较严格的过程检测系统.

Design and implementation of embeded image data processing system base on ARM

Aim at the process detecting system in nowadays of real-time need,designing a low cost and moderate function image processing system.The system use ARM7(S3C44B0X) as core with circuit realize image processing function,multi-communication interface constitute image transmission channels,SD card interface acquire image data.At last design a image processing methods base on uC/OS-II embeded operating system to realize image enhancement,image division and target orientation.The experiment indicates that the system resolve real-time problem well in image on-line processing image veracity also meet the need of process detecting system.The system carry out simply and cost low,especially suitable for process detecting system in consumed power and cubage strict request.
