Abstract:
1. A computer-implemented method for use in location correction of a virtual model of a real-world scene, said computer-implemented method comprising: by a processor coupled to a memory area storing the virtual model and a virtual object in the virtual model, the virtual model representing the real-world scene, said processor: generating the virtual model, including the virtual object; acquiring at least one digital image of a real-world object within the real-world scene, wherein the real-world object corresponds to the virtual object; calculating an image-based positional difference between at least one predefined point on the virtual object and at least one corresponding point on the real-world object; adjusting at least one of a position and an orientation of the virtual object based on the calculated image-based positional difference such that a corrected location of the virtual object with respect to the virtual model corresponds to a location of the real-world object in the real-world scene; and adjusting the virtual model with respect to the corrected location of the virtual object.
