Three-Dimensional Data Recovery Using Image-Based Modeling

Extraction of a three-dimensional model from a set of two-dimensional projections is a well-known problem of contemporary computer science. Termed image-based modeling, solutions to this problem have a number of practical applications ranging from virtual tours and image recognition to generation of physical models from image data. However, this problem remains the subject of active research as it has not yet been solved in the general case. Although this general case has proven very challenging, there are certain special cases where a satisfactory solution can be achieved with minimal human intervention. The following report describes our approach to a general solution to the problem of inferring geometric information from a photographic image. A detailed description of our algorithm and the method of implementation are provided along with sample results demonstrating the capabilities of this approach.
