Method and system for image georegistration

Abstract

Method/system for determining pose of camera using another camera imaging common scene, by capturing first scene image with first camera and obtaining first camera pose by georegistering to 3D-model, extracting scene features in first image, determining 3D coordinates of extracted features by mapping to 3D model, transmitting feature descriptors and feature coordinates, capturing second scene image with second camera, extracting scene features in second image and matching with first image features, determining second camera pose using 3D scene coordinates and corresponding 2D projections in second image. Method/system for determining pose of one camera using another camera in same camera assembly with known relative pose between cameras in assembly, by capturing image of scene with first camera and determining 3D coordinates of first camera by georegistering to 3D-model, and determining pose of second camera based on determined global pose of first camera and relative pose between second camera and first camera.
