System and method for constructing database of dangerous reservoir using unmanned aerial vehicle

摘要

The present invention relates to a system and method for constructing a disaster risk reservoir database, wherein the disaster risk reservoir database building system of the present invention includes a unmanned aerial vehicle (UAV) for shooting a reservoir, And a plurality of images photographed on the unmanned airplane are preliminarily processed, a plurality of preprocessed images are joined, orthogonal images and a DSM (Digital Surface Model) are generated from the combined images, and the orthoimage and DSM Dimensional model of the reservoir, analyzing the risk of the reservoir through the 3D stereoscopic model, and updating the database by reflecting the analyzed data. According to the present invention, by collecting data on a disaster information reservoir by using an unmanned airplane, the operation cost is low, and reservoir information can be obtained quickly and accurately.
