4 Conclusion and Future Works
The AECWT-3DR-Net for 3D test regression produced impressive results, with
RMSE measurements of less than 9.6 mm. The study applied a heterogeneous materi-
al, specifically concrete, for the experiment. The proposed method overcomes the
limitations of traditional methods and produces high accuracy by utilizing the rela-
tionships between signals collected from sensors in multiple locations. In future work,
we will continue to improve the accuracy of detecting cracks.
