Title:
WORK RECOGNITION METHOD
Document Type and Number:
Japanese Patent JPS6478387
Kind Code:
A
Abstract:
PURPOSE:To appropriately recognize a work and to satisfactorily attain the handling of a manipulator by permitting diaphragms which have lightness different from that of the works and which have high light diffusivity to be intervened between an uppermost stage and a preceding stage. CONSTITUTION:At the time of stage-piling plural works (crank shafts) 11, the diaphragms 12 and 13 having light diffusivity are intervened in respective inter- stages. The diaphragms 12 and 13 are provided there and they have a function for making the positions of the arranged crank shafts 11 in a horizontal directions and a function for clarifying a contrast between the crank shafts 11. For clearly separating the loaded crank shafts 11 from background, the color, gloss and the surface form of the diaphragms to be the background are selected in correspondence to the crank shafts 11, and the light diffusivity of the diaphragms 12 and 13 are improved. Thus, the outline of the works are emphasized and the recognition precision of the works is improved. Furthermore, the overlap with the work in a lower stage is eliminated and handling in the hand part of the manipulator is facilitated.
