Structured Light-Based 3D Reconstruction System with Triangular Mesh Hole Repair

Structured light-based 3D reconstruction technology has emerged as a focal point of research in the field of 3D modeling due to its exceptional speed and accuracy. However, occlusion often occurs due to the limited field of view between the camera and the projector, as well as the complex surface of the object. Consequently, defects and holes are generated in the reconstructed model, impairing the model's reconstruction quality. In this study, we propose a hole repair method based on a triangular mesh that yields superior repaired effects. Our method effectively addresses the deficiencies in point cloud caused by occlusions. The difference in model accuracy between the repaired point cloud and the original point cloud is 3.618%.
