Senior Project - 2D|!2D


Extraction of 3D Information from Photogrammetric Images

Senior Project: 1997-1998

GW Hannaway & Associates (GWH&A) has created image processing software for the Aerospace, Research, and Entertainment markets since 1978. Scientific image processing systems and software applications were the main products in the 1980s. In the last six years, the Entertainment marketplace has become a significant user. GWH&A is one of the founders of a new Hollywood company, Silicon Grail, which produced a software application for SGI machines called "Chalice", which has been used for special-effects scenes in many well known movies.

Because of GWH&A's relationship with Silicon Grail, GWH&A was encouraged to create "Grail Science", a scientific skew of the software. Traditional image processing products deal with individual images, but there is increasing need for a product which performs operations on sequences of images. Though in the Entertainment market, a sequence may be a movie scene, in the Scientific market a sequence may be drawn from an experiment over time (time-lapse, real-time, high-speed), or a sequence may result from a stack of 3D sections, from confocal microscope, CAT-scan, or MRI.

The goal of the project was to create a photogrammetric DSO, written in C++, with an X/Motif GUI, which would plug-in to the existing Silicon Grail architecture. This system analyzes the sequence of images and extracts 3D information from them. It then generates VRML that represents the extracted 3D image.
