1Productivity

If traditional scan-matching mapping technology is used, then mapping can be performed in complex environments, but real-time mapping efficiency is poor and accuracy is limited

Engineering Contradiction:

Improvereal-time mapping efficiencyVSAvoidmapping accuracy

Core Design Contradiction:

ProductivityVSMeasurement precision

Solution Approach 1:

The mapping process is segmented into multiple independent parallel tasks including data collection, geo-referencing, map construction, and rendering. Each task is handled by dedicated modules that can operate simultaneously, dramatically improving real-time mapping efficiency while maintaining accuracy through specialized processing for each segment.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent replaces traditional mechanical scan-matching algorithms with a geo-referencing-based system that uses GPS coordinates and timestamp data to directly locate and map sensor readings. This substitution eliminates the need for complex iterative matching computations, enabling real-time processing without sacrificing mapping accuracy.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Measurement precision

If detailed mapping data is collected and transmitted, then mapping accuracy is improved, but data transmission efficiency decreases due to large data size

Engineering Contradiction:

Improvemapping accuracyVSAvoiddata transmission time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system extracts only the essential geo-referencing data (GPS coordinates and timestamps) from sensor readings for transmission and storage. The actual detailed mapping data is processed and rendered locally using this compact reference information, significantly reducing data transmission requirements while preserving full mapping accuracy through the geo-referenced point cloud reconstruction.
