Research Topics


Accurate and cost effective visual databases, containing geometry and texture data, are needed in themilitary and civilian secotrs to produce a realistic description of specific surroundings for training simulators. Currently, geometry data for visual databases are commonly generated by creating three-dimensional models from photographs and terrain elevation maps using modeling software. Present methods to obtain texture data for visual databases rely heavily on land use maps and satellite data. However, the visual data produced by these labor intensive methods lack realism, resulting in noticeable differenced between the computer generated display and the real images. The goal of this proposed Phase II project is to produce the prototype of a portable, easy-to-use, and automated system to extract geometry and texture data from video images of real surroundings using the new analytical methods developed during the Phase I project. To acquire the necessary data, the system will use a camcorder, Global Positioning System (GPS), electronic compass, and laptop computer. Video images will be processed for geometries and textures using methods to identify two-dimensional points of user specified geometeries, calculate the three-dimensional points, and extract textures. Visual databases containing geometry and texture data will be further developed for military and commercial applications.
