摘　　要：针对观测传感网中的灾害应急监测,设计一套基于ZigBee网络的图像监测系统。该系统的感知层与传输层由摄像头模块、无线传输模块、MCU控制模块和电源模块组成;采用低功耗CC2430为主控芯片,实现图像数据的采集与传输;通过SIFT特征匹配算法实现来源于应用层多种终端设备的监测图片的拼接。本系统具有简单、组网灵活、低功耗、低成本等优势,适用于地面无基础设施或灾后应急的图像监测,是空天地多平台、多传感器的协同观测系统的有效补充。For disaster emergency monitoring in intelligent earth observation system, a wireless image monitoring system is pro!aosed based on ZigBee technology. The perception layer and transport layer of the proposed system are made up of camera module, wireless transmission module, micro control- ler unit and power module. A low-powered CC2430 microprocessor is used as main control chip to col- lect and transmit image data. The image sequence can be received and pieced together by a variety of terminal devices in the application layer of the proposed system. Laboratory tests show that the pro- posed system can be applied to infrastructure-less or disaster emergency image monitoring with the advantages of simplicity, flexibility, easy installation, low-power consumption and low cost. It pro- vides an effective supplement for the space-air-ground collaborative observation system of multiple platforms and multiple sensors.
