We present a novel stereoscopic mapping system for use in post-nuclear accident operations. First we discuss a radiation shielded sensor array designed t o tolerate extended cumulative dose using 4 shielding. Next, we outline procedures to ensure timely, accurate range estimation using trinocular stereo. Finally, we review the implementation of a system for(More)
This paper describes a system that semi-automatically builds a virtual world for remote operations by constructing 3-D models of a robot's work environment. With a minimum of human interaction, planar and quadric surface representations of objects typically found in man-made facilities are generated from laser rangefinder data. The surface representations(More)
Alzheimer's disease (AD) is a complex, multifactorial progressive neurodegenerative disease. Pathologically, AD is characterized by extracellular deposits of amyloid beta (Aβ) protein and intracellular accumulation of neurofibrillary tangles (NFTs) of tau. The central role of Aβ protein in the AD etiology is well-established, and its increased deposition in(More)
In astronomy, the light emitted by an object travels through the vacuum of space and then the turbulent atmosphere before arriving at a ground based telescope. By passing through the atmosphere a series of turbulent layers modify the light's wave-front in such a way that Adaptive Optics reconstruction techniques are needed to improve the image quality.
