Classification: CPC H | IPC H

Claim 18:
19. An information generation method comprising:
extracting, from a frame image, a projection image of geometry data of a point cloud and a projection image of attribute data of the point cloud by using an occupancyMap that is generated in accordance with a positional relationship of points in a three-dimensional space, a point cloud representing an object having a three-dimensional shape as a set of the points, and the occupancyMap indicating, for each local area of a frame image, presence or absence of a projection image of the point cloud on a two-dimensional plane; and
generating the point cloud by using the projection image of the geometry data and the projection image of the attribute data that have been extracted wherein
a value of the local area of the occupancyMap is set on the basis of a determination that a plurality of the points includes a disappeared point, the determination being made in accordance with a positional relationship with a neighboring point in a three-dimensional space, and the disappeared point being a point that disappears when the projection image is extracted from the frame image by using the occupancyMap.
