Position Determination Method using Oblique-view Stereo-pair Images

～Proposal and Experimental Verification of Observation Method from Afar using UAV～

Abstract

Ground information captured by UAV (Unmanned aerial vehicle) through nadir viewing is widely utilized in applications such as disaster and environmental monitoring. Additionally, capturing imagery from a distant oblique-viewing allows for immediate data collection and enables observation from a distance. However, the use of oblique imagery from UAV requires the establishment and validation of analysis methods. In our research, aimed at enabling remote observation, we developed an analysis method for oblique-view stereo pair images. This system accurately identi es the targetʼs precise location using capture position and orientation information. Even in cases where the capture position and orientation are unknown, this system can estimate them from the captured images and basing point, facilitating the identi cation of the targetʼs position.
