1Loss of information
If multiple two-dimensional profiles are obtained through surface detection, then the detection data coverage is improved, but the data complexity and difficulty in establishing a three-dimensional model increases
Solution Approach 1:
The patent applies dimensionality change by transforming two-dimensional profile data from multiple measuring lines into a three-dimensional coordinate system. The coordinate conversion module transforms coordinates (x, y, z) from different two-dimensional profiles into a unified three-dimensional space, enabling comprehensive underground structure representation while managing data complexity through systematic coordinate transformation.
