A data processing method includes determining feature points in first point cloud data and feature points in second point cloud data, the first point cloud data and the second point cloud data being used for representing different parts of a same object; performing feature matching between the first point cloud data and the second point cloud data to determine feature points satisfying feature matching condition(s) between the first point cloud data and the second point cloud data, and form a plurality of feature point pairs; determining a transformation matrix in which spatial distances between feature points in one or more feature point pairs of the plurality of feature point pairs conform to a proximity condition; and performing coordinate transformation on the one or more feature point pairs using the transformation matrix to register the first point cloud data with the second point cloud data.
