Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the entire Octree is decoded to obtain a desired region, then the configuration of the whole Octree can be reproduced, but the processing amount and resource usage are unnecessarily increased
Solution Approach 1:
The patent divides the 3D spatial region into multiple blocks with independent coding, allowing selective decoding of only the necessary blocks rather than decoding the entire Octree. This segmentation enables efficient partial decoding while maintaining the ability to reproduce the desired region accurately.
Solution Approach 2:
The patent extracts and codes only the necessary parts of the 3D data by dividing the spatial region into blocks and selecting only the blocks that contain the desired region. This extraction approach reduces the processing amount and resource usage while still obtaining the required 3D structure information.
2Ease of operation
If the 3D spatial region is divided into small regions for independent coding, then each small region can be independently decoded, but the position, shape, size and other characteristics of each small region are limited
Solution Approach 1:
The patent implements dynamic block division where the spatial region is divided into blocks with flexible positions, shapes, and sizes rather than fixed grid-like structures. This dynamic approach allows blocks to be adaptively positioned and sized to match the actual content distribution, enabling independent decoding while maintaining high flexibility.
Solution Approach 2:
The patent applies different coding strategies to different blocks based on their local characteristics. Each block can be independently coded with appropriate parameters for its specific region, allowing flexible adaptation to varying spatial distributions of 3D data while maintaining independent decodability.
3Quantity of substance
If the whole Octree is decoded, then all regions are available, but processing and resource usage are increased due to decoding unnecessary regions
Solution Approach 1:
The patent enables partial decoding by allowing the decoder to select and decode only the specific blocks that contain the desired region rather than decoding the entire Octree. This partial action approach reduces processing energy consumption while still providing sufficient 3D data for the application requirements.

AI summary
There is provided an image processing device and a method that enable partial decoding of 3D data to be performed more easily. Management information of a block as a partial region in a predetermined three-dimensional spatial region including 3D data representing a three-dimensional structure is generated. In addition, a block satisfying a condition specified by a user is selected on the basis of management information of the block as a partial region in a predetermined three-dimensional spatial region including 3D data representing a three-dimensional structure, and coded data of the 3D data within the selected block is decoded. The present disclosure can be applied to, for example, an image processing device, an electronic apparatus, an image processing method, a program, or the like.
