Claim 12:
13. A shot treatment method wherein shot material is ejected from a nozzle towards a workpiece to subject the workpiece to a shot treatment, the method comprising:
storing a reference operation pattern of the nozzle, performed by a nozzle moving mechanism to which the nozzle is fixed and which is capable of modifying a position and a pose of the nozzle with respect to the workpiece, when the workpiece is installed at a reference position and a reference pose within a treatment compartment;
storing three-dimensional model data of the workpiece;
obtaining position and pose information of the workpiece by means of a three-dimensional information obtaining sensor that three-dimensionally captures an image of the workpiece provided within the treatment compartment;
comparing the position and pose information obtained by means of the three-dimensional information obtaining sensor and reference position and pose data when the three-dimensional model data is provided at the reference position in the reference pose and calculating a displacement in a position and pose of the workpiece from the reference position and pose data; and
correcting the reference operation pattern of the nozzle based on the displacement in the position and pose and controlling the nozzle moving mechanism to move the nozzle based on the corrected reference operation pattern.
