| Abstract(in English) | This report describes a method to estimate camera position and posture in 6-DOF for a still image taken on the ground using aerial images that are already existing for many places of the world. For this purpose, most of existing methods estimate camera position and posture in 3-DOF with constraints on camera posture. However, these constraints are not suitable for such applications as augmented reality and three-dimensional measurement which need 6-DOF camera parameters in a wide outdoor scene. In this paper, we present a solution for PnP (perspective-n-point) problem from 2D-to-2D point correspondences between a ground-view image and an aerial image for estimating camera position and posture in 6 DOF (3-DOF absolute posture, 2-DOF horizontal absolute position, and 1-DOF relative height) by minimizing reprojection-error defined between points and projected vertical lines. We demonstrate the performance of our method by comparing it with a conventional method in simulation and real environment. |
