Abstract

In this paper, we proposed the geolocation method using target detection information in infrared images. Our method was applied to geolocation system of hostile targets in ground-to-ground field. The major distortion that has bad effect of geolocation was composed of optic, topography, GPS(Global Positioning System) and IMU(Inertial Measurement Unit) of reconnaissance unit. We proposed enhanced geolocation method to cope with optic and topography distortion using polynomial fitting and slant-range calculation model to overcome earth curvature problem, and the result showed that the performance of our method was good for system requirements.

본 논문에서는 적외선 영상에서 탐지된 표적의 픽셀정보를 이용하여 실제 환경에서의 표적의 위치를 추정하는 geolocation 기법에 대하여 제안한다. 제안하는 기법은 지대지 전장 환경에서 공중 정찰을 통한 적대 표적의 위치를 파악하는 시스템에 적용이 가능하다. 적대 표적의 geolocation에 영향을 주는 요소는, 시스템의 광학적 왜곡, 지형적 왜곡, 정찰 모듈의 GPS(Global Positioning System) 및 IMU(Inertial Measurement Unit) 왜곡을 들 수 있다. 본 논문에서는 광학적 왜곡과 지형적 왜곡에 적응적인 geolocation 을 위하여 광학 정보의 다항식 최적화와 지구 곡률을 고려한 시선거리 계산 기법을 적용하였으며, 3차원 모의 환경에서 실험한 결과 시스템 요구사항 내에서 geolocation의 정확도를 만족함을 확인하였다.
