摘要
The present invention relates to a disaster damage investigation and analysis system using drones and a disaster damage investigation and analysis method using the same. According to an embodiment of the present invention, the disaster damage investigation and analysis system using drones comprises: a drone device photographing a disaster-damaged region from above through a mounted camera module to obtain image information of the disaster-damaged region; and a controller device receiving the image information of the disaster-damaged region from the drone device through wireless communication with the drone device, and processing the transmitted image information through a preset automatic calibration algorithm to obtain 3D modeling information. The automatic calibration algorithm applies preset ground reference point information and interior orientation parameters (IOPs) information of the camera module mounted on the drone device to the image information obtained through the drone device to set up an initial camera model so as to calibrate the image information, and then automatically optimizes the initial camera model while repeatedly adjusting external orientation parameters (EOPs) information of the camera module through bundle adjustment to increase the accuracy of the image information.;COPYRIGHT KIPO 2020
