Feature extraction of three-dimensional objects and visual processing in a hand-eye system using laser tracker

Visual processing is one of the important aspects in researches on an intelligent robot. This paper describes the principle and the construction of a laser tracker as a visual device with an active faculty. This robot's eye can acquire three-dimensional coordinates of a laser spot on an object based on triangulation and then extract features of the object corresponding to the purpose of the intelligent rogot. As its applications, classification of several three-dimensional objects and visual processing in a hand-eye system are performed.
