In recent years, various disasters have occurred frequently due to global warming phenomenon, environmental pollution, and so on. As a result, there is a growing interest in disaster prevention in each country. In particular, it is spurring research and development on systems that can detect and prevent various disasters such as earthquakes, tsunamis, fires, typhoons, floods, heavy rains or landslides in advance.
The current weather forecasting system that monitors the weather changes forecasts a wide area through meteorological satellites, but detailed weather information can not be transmitted to local places such as mountain valleys and riverside amusement parks. In reality, Remains.
For example, when a disaster such as a mountainous valley landslide occurs, the management office receives a primary weather report from the central control agency and delivers it again, so it can not prepare for floods occurring within a short time.
As part of such disaster prevention systems, the conventional disaster alarm system is a system in which disaster alarm systems such as the central government or local government disaster prevention agencies are operated by various disaster observation stations observing rainfall, snowfall, earthquake, And the results were used to judge the likelihood of a disaster, the occurrence of a disaster, and the extent of the disaster, and then alarmed through media such as newspapers and broadcasts.
However, the person visited the expected spot of the disaster and confirmed it by using the equipment which detects various disaster factors at the spot. In this case, it is inevitable to monitor the disaster factors only in some places where disaster is expected due to budget and manpower shortage. In particular, it is impossible to accurately detect minute changes such as terrain that predicts disasters, There was a limit.
In order to overcome the above-described problems, it is an object of the present invention to provide a method for predicting and warning dangerous factors such as a disaster occurring around a user by 3D aerial photographing of a terrain using a drone, It is an object of the present invention to provide a safety prediction method of terrain using 3D aerial photographing.
According to another aspect of the present invention, there is provided a method of controlling a drones, the method comprising: a) setting a shooting region in a central server, setting GPS coordinates at an end portion of the shooting region, and controlling the dron to travel without deviating from an accurate shooting region; b) photographing the terrain with a 3D camera attached to the drones; c) measuring the height of the terrain from the ground with a laser range finder attached to the drones; d) 3D mapping, displaying and accumulating terrain images photographed with the 3D camera, and cumulatively storing the terrain images by time zone; And e) comparing the cumulatively stored 3D mapped images with each other during a predetermined period of time to determine whether the terrain is deformed.
The photographing area is formed in a quadrangular plane, and it is preferable to set the GPS coordinates for each of four vertexes of a quadrangle.
More preferably, the deformation of the terrain is at least any one of a form of the ground, a shape of the mountain, a specific rock or a specific building, a position of the bridge and a moving position of the bridge and an inclination thereof.
If it is determined in the step e that the deformation of the terrain is deformed to be equal to or larger than the reference value stored in advance, an ARS alert call or warning character may be sent to the personal portable terminal in the corresponding area.
The 3D camera captures the X, Y, and Z axes, and maps the captured images to set the three-dimensional elevation and position of the terrain.
According to the safety prediction method of terrain using 3D aerial photographing according to the present invention, 3D aerial photographing of the terrain using a dron and comparison and analysis of the terrain are performed to predict and predict dangerous factors such as a disaster occurring around the user There is a warning effect.
In addition, since collapse of buildings and bridges can be predicted and warned in advance, it is possible to prevent damage to persons.
In addition, according to the present invention, a module or algorithm programmed in the conventional drones can be easily implemented in a simple manner, so that the development cost can be reduced.
