Patent number: 11948337Abstract: The present disclosure relates to image processing apparatus and method that can prevent a reduction in image quality. Geometry data that is a frame image having arranged thereon a projected image obtained by projecting 3D data representing a three-dimensional structure on a two-dimensional plane and includes a special value indicating occupancy map information in a range is generated. The generated geometry data is encoded. Further, the encoded data on the geometry data is decoded, and a depth value indicating a position of the 3D data and the occupancy map information are extracted from the decoded geometry data.

Patent number: 11922579Abstract: There is provided an image processing apparatus and an image processing method that are capable of suppressing an increase in loads when a point cloud is generated from a mesh. Point cloud data is generated by positioning points at intersection points between a surface of a mesh and vectors each including, as a start origin, position coordinates corresponding to a specified resolution. For example, intersection determination is performed between the surface of the mesh and each of the vectors, and in a case where the surface and the vector are determined to intersect each other, the coordinates of the intersection point are calculated. The present disclosure can be applied to an image processing apparatus, electronic equipment, an image processing method, a program, or the like.Type: GrantFiled: December 21, 2022Date of Patent: March 5, 2024Assignee: SONY CORPORATIONInventors: Ohji Nakagami, Koji Yano, Satoru Kuma, Tsuyoshi Kato, Hiroyuki Yasuda
