  • Method and apparatus for apparatus for generating three-dimensional models from uncalibrated views
    Patent number: 7289662
    Abstract: A system for generating three-dimensional models from still imagery or video streams from uncalibrated views, is presented. The system comprises a computer system including a processor, a memory coupled with the processor, an input coupled with the processor for receiving imagery captured from multiple pan-tilt settings of an uncalibrated image capturing device, and an output coupled with the processor for outputting an overall three-dimensional model of a complex scene containing rigid and non-rigid objects. The computer system includes a method for forming a three-dimensional model from uncalibrated views of an object, and a method for automatically stitching together three-dimensional models extracted from uncalibrated views of uncalibrated image capturing device locations, without the need of manual “image registration” of “points in common” between the models.
