SYSTEM FOR FINDING TOPOGRAPHY CHANGE USING PILOTLESS PLANE

摘要

The present invention relates to a system for detecting topography variation using an unmanned aerial vehicle. The present invention provides a system for detecting topography variation using an unmanned aerial vehicle comprising: a remote-controlled unmanned aerial vehicle having a GPS receiver and a distance sensor and outputting a first alarm signal when an output value of the distance sensor is a reference value or less; a server for converting the topographic data of a database to the form of a map; and a terminal visually displaying the map received from the server through a network and the position of the unmanned aerial vehicle on the map, generating a second alarm signal when the distance between an object on the map and the unmanned aerial vehicle is the reference value or less, and determining whether or not the topography is changed by comparing the time when the first alarm signal is received from the unmanned aerial vehicle and the time when the second alarm signal is generated.
