Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If post-processing is used for mapping, then mapping accuracy can be improved, but real-time visualization is delayed
Solution Approach 1:
The mapping process is segmented into multiple threads: data collection thread, processing thread, and rendering thread. This allows simultaneous execution of data acquisition, real-time processing, and visualization, eliminating the sequential delay caused by traditional post-processing while maintaining mapping accuracy through dedicated processing resources.
Solution Approach 2:
The system performs preliminary actions by pre-allocating processing resources and establishing data pipelines before mapping operations begin. The parallel processing architecture is prepared in advance, enabling immediate real-time visualization without waiting for post-processing completion.
2Measurement precision
If complex scan-matching environments are required, then mapping precision can be improved, but adaptability to diverse environments deteriorates
Solution Approach 1:
The system implements a universal mapping framework that can operate in diverse environments including complex scan-matching scenarios. The parallel processing architecture and flexible data pipeline design enable the system to adapt to various environment types (indoor, outdoor, structured, unstructured) while maintaining mapping precision through configurable processing parameters.
