摘要
提出了一种基于Intel PXA255嵌入式微处理器和MC55无线通讯模块的图像采集、压缩与传输的设计方案。在PXA255的平台上,通过选择适合的芯片、无线传输模块并利用MPEG-4视频压缩技术对图像进行压缩后通过GPRS网络来实现无线图像实时传输功能,从而实现功耗低、体积小、数据传输速度快和携带方便等特点,特别适用于远程实时监控、工业控制和智能家居等环境。
A design scheme of capturing, compressing and transmitting images is proposed, which is based on Intel PXA255 microprocessor and MC55 wireless transmission module. In order to realized the function of wireless image real-time transmission, we choose appropriate chip, wireless transmission module, adopt MPEG-4 video compression technology compress image and make use ofGPRS network send it on the PXA255 platform. The system is low-cost, has a small size and fast speed of transmitting data, and is easy to carry, so it is suitable for the situation of remote real-time monitor, industry control field and smarthome.
