Abstract
Methods for automatic recognition of the electrode imprints on digital images in spot welding of the three-layer honeycomb structures-correlation, statistical, and neuron network ones-have been investigated. The algorithms for recognition of the electrode imprints on surface of a three-layer honeycomb structure using an optical sensor system have been developed. High efficiency of the developed algorithms has been demonstrated.
