Abstract: An apparatus for matching a point cloud and a CT image according to one embodiment disclosed in the present document obtains target point cloud data from a surface image of an object photographed by a 3D camera; and matches the obtained target point cloud data with reference point cloud data by using normal distribution transform, wherein the reference point cloud data refers to data obtained from previous point cloud of the object or a CT image of the object, and on the basis of the matching, transformation information between the target point cloud data and the reference point cloud data may be provided.
