ABSTRACT:
A work pick-up apparatus which picks up an object work out of a plurality of works held on a container case through visual recognition of the position of the object work by a visual sensor. The apparatus comprises: a memory circuit for storing shape characteristic information concerning the shape characteristic of the object work; an input circuit for externally inputting approximate position information representing an approximate position of the object work on the case, the approximate position information being expressed in terms of a coordinate system associated with the work pick-up apparatus; and a measuring circuit for measuring the pick-up position of the work in terms of the coordinate system associated with the pick-up apparatus, by processing the image information concerning the work obtained through the visual sensor in accordance with the approximate position information and the shape characteristic information.
