(54)Title:METHOD AND APPARATUS FOR PROCESSING THREE DIMENSIONAL OBJECT IMAGE USING POINT CLOUD DATA

(57)Abstract:An apparatus and method are provided for compressing a three-dimensional(3D)object image represented by point cloud data.The method includes positioning the3D object image into a plurality of equi-sized cubes for compression;determining3D local coordinates in each of the plurality of equi-sized cubes and a cube index for each point of the3D object image positioned in the plurality of equi-sized cubes;generating two-dimensional(2D)image data based on the3D local coordinates and the cube indexes;and storing the2D image data in a memory.The2D image data includes at least one of2D geometry data,2D meta data,or2D color data.
