Solution Overview
Problem
Current technologies lack the ability to provide random access functionality for encoded three-dimensional data, which is essential for efficient encoding and decoding of three-dimensional data, particularly in applications involving mobile objects that require dynamic and efficient data transmission and display.
Innovation Solution
A method and device for encoding and decoding three-dimensional data that divides the data into random access units, allowing for efficient encoding and decoding by referencing other units, and selectively transmitting data based on the intended use and conditions, such as the mobility and communication status of the object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If three-dimensional data is compressed and encoded for accumulation and transmission, then data transmission efficiency is improved, but random access functionality is lost
Solution Approach 1:
The patent segments the encoded three-dimensional data into multiple independent random access units, where each unit can be independently decoded and accessed. This segmentation allows the system to maintain random access functionality while keeping the overall data compressed and encoded for efficient transmission.
2Quantity of substance
If point cloud data is compressed to reduce data amount, then storage and transmission requirements are reduced, but processing complexity increases
Solution Approach 1:
By dividing the point cloud data into multiple random access units with independent encoding structures, the patent reduces the processing complexity of individual units while maintaining overall data compression. Each unit can be processed independently, making the system more manageable despite the compression requirements.
3Productivity
If encoded three-dimensional data is transmitted efficiently, then communication bandwidth is optimized, but the ability to selectively transmit data based on conditions is reduced
Solution Approach 1:
The patent segments encoded three-dimensional data into multiple random access units that can be selectively transmitted based on communication conditions, mobile object status, and display requirements. This segmentation enables flexible data transmission while maintaining overall communication efficiency.
Solution Approach 2:
The patent implements dynamic selection of which random access units to transmit and decode based on real-time conditions such as mobile object mobility, communication status, and display device capabilities. This dynamic approach optimizes both communication efficiency and adaptability to varying conditions.

AI summary
A display method is a display method performed by a display device that operates in conjunction with a mobile object, and includes: determining which one of first surrounding information, which is video showing a surrounding condition of the mobile object and is generated using two-dimensional information, and second surrounding information, which is video showing the surrounding condition of the mobile object and is generated using three-dimensional data, is to be displayed, based on a driving condition of the mobile object; and displaying the one of the first surrounding information and the second surrounding information that is determined to be displayed.
