Patent ID: 8761921

Claim:
An operation position locating system which confirms a position where a part is attached to a product in a manufacturing process in which the part is attached to the product using a tool, the operation position locating system comprising: a completion signal output unit configured to output a signal which is caused by the tool and which indicates completion of attaching the part to the product; and a processor configured to capture, from a plurality of cameras each configured to take an image of a range including the product and the tool, a plurality of images of the range upon receipt of the signal, to detect a three-dimensional position and a three-dimensional direction of an operation table and a three-dimensional position and a three-dimensional direction of the tool via image recognition using the plurality of captured images, wherein the operation table includes a leg portion which enables the operation table to move on a floor as desired by an operator and a table plate which is rotatable as desired by the operator with respect to at least one axis, and the product is fixed to a determined position on the operation table to keep a predetermined positional relation between the operation table and the product, to calculate a three-dimensional position and a three-dimensional direction of the product from the three-dimensional position of the operation table, the three-dimensional direction of the operation table, and the predetermined positional relation, to calculate a three-dimensional position of the part from the three-dimensional position and the three-dimensional direction of the tool, to search design data in which three-dimensional coordinates of each of a plurality of three-dimensional positions to which a plurality of parts are to be attached are included and represented according to a three-dimensional coordinate system based on the product, for a three-dimensional position that is one of the plurality of three-dimensional positions and that matches the calculated three-dimensional position of the part, and to identify which of the plurality of three-dimensional positions the part has been attached to by the tool, according to a result of the search of the design data.
