“In the field of 3D reconstruction, researchers have proposed an innovative adaptive segmentation method to address the impact of discontinuous positions on the accuracy of phase measurement contouring. This method effectively determines discontinuous positions and expands relative phase into absolute phase through adaptive directional coherence algorithm. Both simulation and actual experiments have verified the effectiveness of this method, significantly improving the accuracy of 3D reconstruction. This research achievement not only provides new ideas for the development of phase measurement profilometry, but also opens up new directions for research in the field of high-precision 3D reconstruction.”
