The robot vision system VIRO for flexible part recognition and loading of processing machines with high precision

摘要

The robot vision system VIRO is presented in a special application for flexible part recognition and precise gauging. The shape variation of the parts can be nearly infinite, but the valid shapes can be described by several general constraints. A rule-based system for part recognition is developed. To achieve the necessary precision in spite of large part dimensions, a two-stage measuring cascade with an adapted spatial resolution has been developed. The precision achieved by this principle is discussed.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
