| 摘 要： | 针对远程采集的气象图像信息在传输过程中数据容易丢失的问题,提出了一种基于小波压缩终端补偿的远程气象图像信息传输方法:用远程通信卫星采集气象视频图像数据,通过无线传感网络,采用小波压缩技术,在节点上压缩后再传送;终端补偿算法能补偿气象图像数据信息在传输中的损失.实践证明,该方法能够增强远程气象雷达视频监控图像信息的完整性.

| Abstract: | According to the problem of remote acquisition meteorological image data easy to lose in a transmission process,a remote transmission method of meteorological image information is proposed based on wavelet compressed terminal compensation.Meteorological video image data is collected by remote communication satellite,compressed in ascending node and delivered through the wireless sensor network,using wavelet compression technology.Terminal compensation algorithm can compensate for loss of meteorological image data in information transmission.Practice shows that this method can improve the integrity of image information of remote weather radar video monitor. |
