Claim 7:
8. The method for merging the surface skin three-dimensional data according to claim 5, wherein step S300 specifically is: finding the closest points in the point cloud Y of the design model three-dimensional data for each measuring point xi in the point cloud X of the actually-measured three-dimensional data, wherein the closet points are denoted as yi′, yi′∈Y, a unit normal vector corresponding to yi′ is ni′, ni′∈N, a corresponding neighborhood radius is ri′, ri′∈R, yi′ forms a set Y′={y1′, y2′, . . . , yi′, ym′} of the closest points, ni′ forms a unit normal vector set N′={n1′, n2′, . . . ,ni′, . . . , nm′} of the closest points, ri′ forms a neighborhood radius set R′={r1′, r2′, r3′, . . . , ri′, . . . , rm′} of the closest points, and the points in the point cloud X are in one-to-one correspondence with the points in the closest point set Y′, the normal vectors in the set N′, and the radii in the set R′.
