AI Technical Summary
The lack of a mature water level correction model in the existing technology leads to uncertainty in the calculation of water level at underwater measuring points, and the data from a single observation station is not representative enough, resulting in large errors.
By setting up multiple water level observation stations, recording their spatial coordinates, establishing triangulation relationships, calculating the area ratio between underwater measuring points and adjacent water level observation stations, and automatically reconstructing the triangulation relationships when the number or location of observation stations changes, and combining the instantaneous water level for weighted calculation to identify the water level of underwater measuring points.
It achieves geometric consistency and dynamic adaptability in water level calculation, reduces errors caused by local anomalies, and improves the accuracy and robustness of water level calculation.
