A component 4 located at the end of a robotic end effector 2 is illuminated by two light sources 6. Two CCD array sensor cameras 10 and 12 for detecting gray level images receive light from the component 4 through a beam splitter 8. The component 4 has a multiplicity of leads along its sides. A vision processor 20 includes a frame grabber 22 converting analog video signals from cameras 10 to 12 to digital and storing them in memory 24. The vision processor 20 then determines presence, position and orientation of component leads prior to placement. Image processing decreases computational complexity by representing two dimensional image areas of interest by one dimensional summation profiles. <IMAGE>
