Solution Overview

Problem

Existing methods for creating three-dimensional data lack efficiency in reducing data transmission and simplifying device structures, particularly in applications involving autonomous vehicles and robotics.

Innovation Solution

A three-dimensional data creation method that involves a client device and a server, where the client creates three-dimensional data using sensor information and transmits this information to the server for processing, allowing for reduced data transmission and simplified device structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If three-dimensional data is created and transmitted using existing methods, then the surrounding area information can be captured, but the amount of data to be transmitted becomes large

Engineering Contradiction:

Improvesurrounding area informationVSAvoiddata transmission amount

Core Design Contradiction:

Loss of informationVSQuantity of substance

Solution Approach 1:

The patent extracts and transmits only the essential sensor information (raw data from sensors) rather than complete three-dimensional data. The client device creates three-dimensional data locally using its own sensors, and only transmits the minimal sensor information needed to the server, significantly reducing data transmission volume while preserving the ability to reconstruct surrounding area information.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system segments the three-dimensional data creation process into two parts: local processing at the client device (creating 3D data from sensor information) and remote processing at the server (receiving only sensor information). This segmentation allows the client to maintain full three-dimensional data locally while transmitting only minimal sensor data to the server.

Inventive Principle:

Principle #1Segmentation

2Device complexity

If three-dimensional data processing is performed locally, then the device structure becomes complex, but if transmitted to server, then data transmission amount increases

Engineering Contradiction:

Improvedevice structureVSAvoiddata transmission amount

Core Design Contradiction:

Device complexityVSQuantity of substance

Solution Approach 1:

The client device performs self-service by creating its own three-dimensional data using its onboard sensors. This eliminates the need for complex device structures with multiple specialized sensors, as the device uses its existing sensor suite to generate three-dimensional representations of the surrounding area independently.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The sensor information serves multiple functions: it is used by the client device to create three-dimensional data for local processing, and simultaneously transmitted to the server for remote processing. This multi-functionality of the sensor information transmission reduces overall system complexity while maintaining both local and remote processing capabilities.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A three-dimensional data creation method in a client device includes: creating three-dimensional data of a surrounding area of the client device using sensor information that is obtained through a sensor equipped in the client device and indicates a surrounding condition of the client device; estimating a self-location of the client device using the three-dimensional data created; and transmitting the sensor information obtained to a server or an other client device.
