초록

본 논문에서는 하이브리드 항법변수 추정 시스템의 일부분인 IRS 위성영상을 이용한 절대위치 추정기법을 다룬다. 빠른 에지 기반 정합을 위하여 accumulator cell로 이루어진 accumulated buffer (AB)를 이용한 정합방법을 제안하였다. 항공기에서 촬영한 두 가지 실제 연속 영상들을 이용한 실험 결과로부터 제안한 AB 정합 방법의 성능을 분석하고, 거리 오차 측면에서 전체 항법변수 추정 시스템에서의 절대위치 추정기법의 효율성을 보였다.

This paper presents an absolute position estimation method using Indian remote sensing (IRS) satellite images, which is a part of a position estimation (PE) system. The accumulated buffer (AB) matching method is proposed, in which a set of accumulator cells is employed for fast edge-based matching. By computer simulations with two sets of veal aerial image sequences, the performance of the AB matching method is analyzed and its effectiveness is shown in terms of the position error in the hybrid PE system.
