Mesh Encoding Granularity Control for 3D Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mesh compression methods struggle to independently control the granularities of UV coordinates and vertex positions, leading to difficulties in optimizing image resolution and encoding efficiency.
Innovation Solution
An information processing device and method that encode meta information, geometry images, and texture images with independently set granularities, allowing for separate control of UV coordinates and vertex positions, thereby optimizing image resolution and encoding efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the geometry image and texture image have the same image size (resolution), then the encoding process is simplified, but the granularities of UV coordinates and vertex positions cannot be independently controlled
Solution Approach 1:
The patent divides the encoding process into separate units: a meta information encoding unit for vertex positions and a texture image encoding unit for UV coordinates. This segmentation allows independent control of granularities for geometry and texture, resolving the contradiction between simplified encoding and independent control capability.
2Measurement precision
If the resolution of geometry image or texture image is increased, then the granularity of UV coordinates and vertex positions is improved, but the encoding efficiency decreases due to redundant pixel compression
Solution Approach 1:
The patent extracts the vertex position information from the image data and encodes it separately as meta information. This extraction eliminates redundant pixel compression that would occur if vertex positions were encoded within the image data, thereby improving encoding efficiency while maintaining high granularity through independent meta information encoding.

AI summary
There is provided an information processing device and method capable of independently controlling granularities of UV coordinates and vertex positions. Meta information including vertex information with a first granularity which indicates coordinates of vertices of a mesh is encoded, a geometry image with a second granularity of the mesh is encoded, a texture image with a third granularity of the mesh is encoded, and encoded data of the meta information, encoded data of the geometry image, and encoded data of the texture image are provided. The present disclosure may be applied to, for example, an information processing device, an electronic device, an information processing method, a program, or the like.
