METHOD OF CAPTURING THREE-DIMENSIONAL (3D) INFORMATION ON A STRUCTURE

摘要

A method of capturing three-dimensional (3D) information on a structure includes using at least one physical camera located at a first position to obtain a first image set containing at least one image of the structure, the first image set comprising one or more images; reconstructing 3D information from the first image set; obtaining 3D information from a virtual camera out of an existing global model of the structure; determining a correspondences between the obtained 3D information and the reconstructed 3D information; determining camera motion between the obtained 3D information and the reconstructed 3D information; and updating the existing global model by entering the obtained 3D information using the determined camera motion.
