Video Modeling: A New Paradigm for Reproducing Complex Engineering Artifacts on Computer

Part of: Digital Image Processing: Techniques and Applications in Civil Engineering

Abstract:

This paper introduces a novel approach for automatically creating accurate computer models of existing, physical artifacts. Based on the projected silhouettes of the object, when viewed from different viewpoints, our algorithm efficiently combines the digital information into an incrementally refined three dimensional representation. We have designed the algorithm with two requirements in mind, namely: a) accuracy, i.e. the resulting computer model should retain the overall properties of the real object and also preserve fine details; b) progressive refinement, i.e. a relatively coarse model should be rapidly generated and finer detail progressively reconstructed as more images are available. We demonstrate our algorithm by comparing an original artifact and resulting computer model.
