THREE-DIMENSIONAL DATA MATCHING DEVICE AND METHOD

A method and a device for registering three-dimensional data are disclosed. The method for registering three-dimensional data comprises: generating first two-dimensional data by two-dimensionally converting first three-dimensional data indicating a surface of a three-dimensional model of a target, generating second two-dimensional data by two-dimensionally converting second three-dimensional data indicating at least a part of the three-dimensional surface of the target; determining a first matching region in the first two-dimensional data and a second matching region in the second two-dimensional data by matching the second two-dimensional data to the first two-dimensional data; setting, as initial position, a plurality of points of the first three-dimensional data, which correspond to the first matching region and a plurality of points of the second three-dimensional data, which correspond to the second matching region; and registering the first three-dimensional data and the second three-dimensional data using the initial position.
