Abstract: PURPOSE: A device for recognizing a shape of car parts using the neural network is provided to automatically classify the shape of a pattern classification object by using a signal detected from optical sensors and a pattern recognition algorithm. CONSTITUTION: Pattern classification object transporters(01-06) transport a pattern recognition object such as wheels(71-73). A light source(31) irradiates light to the pattern classification object.
