METHOD AND SYSTEM FOR CAMERA ASSISTED MAP AND NAVIGATION

The subject disclosure provides a computer-implemented method and computer system for use in navigating in a facility. For example, the computer-implemented method comprises: receiving, from a camera, at least one image; estimating, by a processor, a current location of the camera in the facility based on the at least one image and model data of the facility; generating, by the processor, a virtual path from the current location of the camera to a destination location in the facility using the model data of the facility; and generating and outputting navigation information to the destination location according to the virtual path.
