Fuzzy distances for proximity characterization under uncertainty
Models of objects used in planning motions for robots are considered in this paper. A fuzzy approach to handle imprecision in estimated object location is presented. Procedures for computing fuzzy distances between a pair of objects are developed. The procedures are analyzed for their computational complexity. The utility of the distance computations in reasoning about spatial relationships is illustrated. (C) 1999 Elsevier Science B.V. All rights reserved.
