Abstract
Application of Three-Dimensional Chromo-Stereoscopy in GIS
Track: Remote Sensing Imagery
Author(s): Chris Russelavage
Chromo-stereoscopy is an innovative way to evaluate digital imagery and elevation data in three dimensions. The technology is based on the integration of aerial or satellite imagery with a digital elevation model that has been "level-sliced" with color ranging from violet to red. The resulting image depicts the imagery with features that are lower in elevation showing a violet to blue color, while the highest terrain features are shown in red. Unlike the traditional 3-D process that requires two images, chromo-stereoscopy utilizes a single image and the encoding color to carry the z positional information.
ChromaDepthTM glasses are used to obtain the 3-D effect. The completely clear glasses are equipped with specially manufactured prisms to enhance the apparent depth of the differently colored parts of the image for each eye. The glasses pull forward the color red to the foreground and sort the remaining colors according to their position in the rainbow. A 3-D stereoscopic image is the result. Chromo-stereoscopy offers an effective way to interpret relative elevation difference in a variety of remotely sensed imagery.
