长江山区航道能见度监测系统的开发

Development of visibility monitoring system in the Yangtze River mountainous area

设计了一套基于图像的长江山区航道能见度监测系统,主要包括数据采集模块与学习模块、能见度计算单元以及报警与通信模块。实现了信息采集、基于图像的能见度估计算法,并结合D-S证据理论实现了基于多传感器的能见度估计融合算法。能见度计算模块中报警模块可以监测能见度的动态变化情况,并依据规则发出预警信息,该系统已实现并得到验证。

A image based visibility monitoring system for the Yangtze River in mountainous area is designed, including data acquisition module, learning module, visibility calculation module and alarm and communication module. The algorithm of information acquisition and visibility estimation based on image is realized, and the fusion algorithm based on multi sensors is realized by combining the D-S evidence theory. The alarm unit can monitor the dynamic changes of visibility according to the rules. The system has been implemented and validated.
