ABSTRACT:
An object or scene viewed by the programmable optical processor based machine vision system is converted into a video signal representative of a spatial orientation and position of a viewed object being viewed. Reference information stored within a system control processor and indicative of a desired object to be identified and its spatial orientation and position of is used to produce a reference video signal. Both the object video signal representative of the object being viewed and the reference video signal representative of the desired object to be identified are converted into incoherent optical representations of these signals which are optically parallel processed in order to obtain a cross-correlation of the respective signals. This cross-correlation is converted into an electrical signal and is evaluated using any suitable known correlation evaluation technique in order to determine whether a high degree of correlation exists between the object being viewed and its position and orientation and the reference signal indicative of a desired object to be identified and its orientation. If a high degree of correlation exists, the effector control processor is provided with information related to the object so that the effector control processor may control a robotic manipulator in a desired manner. If a high degree of correlation does not exist between the respective signals, new object signal or reference signal information related to the object being viewed is iteratively correlated with the remaining original signal in order to determine the degree of correlation between these two signals.
