Abstract
A method, computer program, and computer system is provided for 3D pose graph reconstruction. 3D reconstruction of indoor buildings for VR/AR applications, such as virtual touring, digital museum, and virtual home sale, may be performed based on estimating pose graph and transformation matrix between cameras by recognizing markers on the ground in panorama images. Image data corresponding to one or more views of a first camera is received. One or more markers corresponding to a second camera are identified within the received image data. A pose graph corresponding to the one or more views of the first camera is constructed based on the identified one or more markers, the pose graph comprising at least an edge.
