Abstract
A work system includes an arm mechanism, a position and an orientation of which are configured to be changed so as to process an object placed on a work area, a member arranged at a distal end portion of the arm mechanism to receive a light projection pattern for calculating a position and an orientation of the distal end portion of the arm mechanism, and an irradiation unit configured to form the light projection pattern on the member and on the object by irradiating the member and the object with pattern light. In addition, an image sensing unit senses an image of the object and is fixed at a position independent of the arm mechanism, and a first calculation unit calculates a position and an orientation of the distal end portion of the arm mechanism and an irradiation plane of the pattern light based on the light projection pattern formed on the member. A second calculation unit calculates a position and an orientation of the object based on the calculated irradiation plane and the light projection pattern formed on the object.
