　　　A performance of the feature-point matching using a concave target marker is investigated for three dimensional (3D) surface shape data given by a grating projection method. Multiple corresponding points are previously created from a surface shape measurement of the concave target markers, and a coordinate transformation matrix that serves as an interface between two sets of 3D shape measurement data is obtained from the feature-point matching with singular decomposition method. Then, effects of the number of the target marker on matching accuracy are discussed for the surface shape measurement data of the spherical mirror model. The results showed that the feature-point matching using the concave target marker connects two sets of the 3D surface shape measurement data at 40 μmRMS accuracy regardless of the number of the corresponding points. This matching accuracy is roughly the same as that achieved by the surface shape measurement using the grating projection method.
