Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating and encoding three-dimensional data lack functionality for random access, leading to inefficiencies in data representation and transmission.
Innovation Solution
A method and device for encoding three-dimensional data that divides the data into random access units, enabling random access on a processing unit basis, with features like quantization and prediction to optimize encoding and decoding processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If three-dimensional data is encoded without random access functionality, then encoding and decoding processes are simpler, but data transmission efficiency and accessibility are reduced
Solution Approach 1:
The patent divides three-dimensional data into multiple random access units, each capable of independent encoding and decoding. This segmentation enables selective transmission and processing of specific data portions without requiring the entire dataset, thereby improving transmission efficiency and accessibility while maintaining manageable complexity through standardized unit structures
2Measurement precision
If detailed three-dimensional data is created, then data representation accuracy is improved, but data amount increases requiring more compression
Solution Approach 1:
The patent enables selective transmission and processing of only the necessary portions of three-dimensional data through random access units. Instead of transmitting the complete detailed dataset, the system can transmit only specific units required for particular tasks, reducing data quantity while maintaining the necessary representation accuracy for the intended application

AI summary
A three-dimensional data creation method for use in a vehicle including a sensor and a data receiver that transmits and receives three-dimensional data to and from an external device. The three-dimensional data creation method includes: creating second three-dimensional data based on information detected by the sensor and first three-dimensional data received by the data receiver; and transmitting, to the external device, third three-dimensional data that is part of the second three-dimensional data.
