Abstract

In this research, an unmanned helicopter based system has been developed for monitoring river environment. Two digital cameras, two IR cameras, and GPS are mounted on an unmanned helicopter to acquire detailed information from low altitude which is different from a satellite or a plane. The monitoring is carried from the sky, but the resolution and accuracy are very high. The data can be easily acquired collectively with safety and mobility, because of the utilization of an unmanned helicopter. Moreover, unmanned helicopter monitoring has been conducted several years to evaluate usability of the system for river environment changes, such as distribution of plants, geographical features of river, and so on. Also, effectiveness of unmanned helicopter based data has been proven by comparing with existing data such as satellite image.
