Abstract
After work is performed according to certain working parameters by an automatic work processing apparatus, the just finished work undergoes an imaging operation by use of an imaging apparatus. Outputs from the imaging apparatus are converted into binary values to obtain a line image, which is then analyzed to evaluate the finished work by comparing the binary values to reference values. If the finished work is not satisfactory, then a deviation between the binary and reference values occurs. A control system receives the deviation data and automatically changes some of the working parameters thereby attaining a satisfactory quality of the work.
