针对ZigBee技术短距离、低速率、低复杂度的传输特性,面对数据量较大的图像时,需要将图像先处理后再进行传输。文中介绍了系统的各个硬件节点的设计和各个模块软件程序的设计,利用CMOS摄像头进行图像的采集,最后通过图像压缩与解压缩技术实现了图像的传输。通过实验测试,最终可以得到分辨率为320*240,大小约为13 kB的清晰图像。文中也对图像传输的关键技术进行了详细的介绍,对实现大数量的数据通过ZigBee网络传输,具有一定的研究意义和实用价值。

ZigBee technology owns transmission properties of the short distance, low speed rate and complexity. When it was used to transfer a large amount of data like image,the image should be processed firstly,then transferred. It introduces each node hardware design and software program design of the system,using CMOS camera to collect image and transfer through the ZigBee network based on the image compression and decompression technique. Through the experiment test,eventually can be able to get a clear image that the resolu-tion is 320*240 and the size is about 13 kB. Simultaneously make a research on the key technology about image transmission in detail, which has a certain research significance and practical value for the big data's transmission using ZigBee network.
