Paper Abstract

Reflective fiducial marks, or targets, permit the location of objects relative to a robot. Usually, object luminance falls off as the inverse square of the distance from the source. However, selected retroreflective marks illuminated by a source near the sensor can have luminances which are almost constant over a wide range of distances and which are also over one hundred times greater than those of diffuse reflectors. Retroreflective materials and illuminator design guidelines are discussed.
