Abstract: Provided is point-based efficient three-dimensional (3D) information representation from a color image that is obtained from a general Charge-Coupled Device (CCD)/Complementary Metal Oxide Semiconductor (CMOS) camera, and a depth image that is obtained from a depth camera. A 3D image processing method includes storing a depth image associated with an object as first data of a 3D data format, and storing a color image associated with the object as color image data of a 2D image format, independent of the first data.

Abstract: Disclosed are data storing and processing methods or apparatuses which may efficiently perform a process of retrieving neighboring points between points stored in a leaf cell in a point-based 3D data expressing method. A computer-readable recording medium having stored thereon instructions for implementing a method of three-Dimensional (3D) data processing, the instructions including an instruction set of connecting each of a plurality of points with a leaf cell of a spatial tree structure; an instruction set of assigning a ball to correspond to each of the plurality of points; and an instruction set of connecting the ball with a leaf cell intersecting the ball.
