基于Windows CE的嵌入式开发研究
Research of Embedded Development Based on Windows CE
【摘要】 近年来基于嵌入式系统的数字化产品在全球范围内得到了突飞猛进的发展,嵌入式技术已成为一个研究热点和消费热点。而Windows CE由于它的多任务、实时性、模块化、强大的通信能力等特点,在嵌入式系统的诸多领域都有了广泛的应用。本文首先探讨了嵌入式系统的特点,分类,前景,然后对各种嵌入式操作系统和Windows CE的特点及开发工具进行分析比较,接着介绍一个我们在Microsoft Windows CE 5.0环境下基于eBoxII开发的智能家居安防保全系统eDog。eDog 可以通过摄像头将采集到的实时视频图像进行运动检测,当发现有运动产生时,通过拨打电话等多种方式自动向用户发出警报,同时将实时捕获的图像上传到ftp 服务器。文章的最后详细阐述了eDog的图像采集模块,运动图像检测模块,图像压缩模块,FTP上传模块的实现过程,并对我们所提出的运动检测算法,视频捕捉算法等做了详细的说明。
