Method and system for constructing a virtual reality environment from spatially related recorded images

Abstract

A simulation of a real environment is constructed from a series of recorded frames that each contain an image of the real environment and each have data recording the associated position and orientation within the real environment. The series of image frames is first grouped into frame groups so that each frame group includes only recorded frames that have closely spaced associated positions. Logical links are then created between neighboring frame groups, where the logical links are indicative of navigation paths permitted during simulation between positions associated with the frame groups thus linked. The environment is then simulated by displaying a recorded frame belonging to a current frame group. In response to an input specifying a desired movement within the simulation, a recorded frame from a neighboring frame group of the current frame group is displayed instead.
