Abstract

A semiautonomous roving vehicle is suitable for planetary exploration before the establishment of a human presence there. Such a vehicle uses cameras for acquiring visual input during daylight operations and low-light-level intensified cameras forscene input at night. It must, therefore, operate over a wide range of illumination. Solar illumination presents challenging input to the correlator because different portions of objects are illuminated, and shaded areas vary with the object-illumination angle.
