Claim:
1. A method of verifying a surgical operation image matching in which a three-dimensional reference image of a target acquired before surgery and a three-dimensional measurement image of the target are matched, the method comprising: obtaining by a shape measurement apparatus, three-dimensional reference image of a model including the surgical area, wherein the model is physically manufactured and a reference object is physically attached to the model; providing, by the shape measurement apparatus, grid patterned light onto the model and the reference object to obtain a reflection image of the model and the reference object; measuring, by the shape measurement apparatus, a three-dimensional shape of the model and the reference object by using the reflection image to obtain a three-dimensional measurement image of the model and the reference object from the three-dimensional shape; matching, by a processor, the three-dimensional measurement image of the model and the reference object and the three-dimensional reference image of the model and the reference object based on a surface of the model; obtaining, by the processor, a reference position of the target in the three-dimensional reference image of the model and the reference object and an estimated position of the target, wherein the estimated position of the target is a position estimated relatively from the reference object in the three-dimensional measurement image of the model and the reference object; comparing, by the processor, the reference position of the target with the estimated position of the target; and verifying, by the processor, the surgical operation image matching based on a result of the comparison.
