REMOTE OBSERVATION METHOD AND SYSTEM BY CALCULATING AUTOMATIC ROUTE OF UNMANNED AERIAL VEHICLE FOR MONITORING CROPS

摘要

Disclosed are a remote observation method through automatic route calculation of an unmanned aerial vehicle and a system thereof. According to the present invention, the remote observation method uses unmanned aerial vehicle (100) which includes a photographing unit (140) which photographs cropland, determines crops according to their growth stage, and acquires image data according to the distribution, and a position information detector (120) which detects position information while the unmanned aerial vehicle (100) aviates along the pre-determined route. The remote observation method includes: a step (a) of preparing geographic information data where a cadastral map layer, an aerial image layer, and a DEM layer of a cropland overlap; a step (b) of preparing crop statistics data according to growth of the crops in the cropland; a step (c) of preparing non-crop data reflecting the height of an object which is not crops; a step (d) of calculating the flight altitude and route of the unmanned aerial vehicle (100) by using the geographic information data, the crop statistics data, and the non-crop data; a step (e) of photographing cropland through the flight of the unmanned aerial vehicle (100) which follows the flight altitude calculated in step (d) and generating positional image data; and a step (f) of receiving the positional image data through an automatic route calculation unit (600) located in the ground.
