Visualizing terrain and navigation data
Tsung-Ming Tsai, David J. Coombs, Billibon H. Yoshimi, Ernest Kent · 2001
Terrain and navigatioji data have been collected from sensors mounted on a)] autonomous offroad vehicle.Data include range images from scanning laser range imagers, position and orientation estimated from GPS and inertied devices, and color images registered with the laser range data.These data have been visualized as static models with interactive displays and as 3D movies (seipiences of 3D range images) displayed nominally from the sensor's viewpoint bat also with some interactive control of the vantage point.Displav technologies have ranged from J'RML (Virtual Realit}' Modeling Language) alone to immersive stereo displays.Design choices in the display (f the data and their effect on the visual impact are discussed.The abilinto rapidly and interactively visualize these data has enabled critical insights into the data that would otherwise have been difficult to achieve.
