Abstract
A method and apparatus utilizing one or two cameras are described for visually inspecting a polygonal component located at the end of the robotic end effector for determining presence, position and orientation of component leads prior to placement. Image processing improvements are provided for decreasing computational complexity by representing two dimensional image areas of interest, and each containing leads along one side of a component, by one dimensional summation profiles.
