无人智能技术在排污口识别中的应用

Application of unmanned intelligent technology in ssewage outlet identification

排污口是城市内河的主要污染源之一,全面掌握排污口的位置和数量意义重大。传统排污口清查方法多采用人工巡查方法,耗时耗力且准确性低。无人机、无人船等新型技术的不断发展,为清查城市内河排污口提供了新的技术方法。本文以南京市城市内河为试验区,采用无人机搭载不同载荷(光学与双光相机)、无人船搭载侧扫声呐开展清查河流排污口的试验。试验结果表明,无人机、无人船等技术可识别河流中的排污口,其中,无人机搭载不同载荷可识别河流水面以上的排污口,无人船搭载侧扫声呐可识别水面以下的暗排污口。

Sewage outlet is one of the main pollution sources of urban river.It is of great significance to know the location and quantity of sewage outlets.The traditional sewage outlet identification method is time and labor consuming,and the identification accuracy is low.The continuous development of UAV,unmanned ship and other new technologies has provided new technical method for the identification of sewage outlet.By using UAV with different loads(optical and dual-light cameras),unmanned ship with side scan sonar technology,the paper took the river in Nanjing as the experimental area to carry out the sewage outlet identification experiment.The experiment results showed that the sewage outlets could be identified.The UAV with cameras could identify the sewage outlets above water,and the unmanned ship with side scan sonar could identify the sewage outlets below water.
