Improved Hole Repairing Method Based on Wavefront Method

Abstract Due to the emergence of 3D scanning technology, in the process of acquiring spatial information of the model, incomplete data often results in the loss of model data, which leads to holes in the acquired digital model. The defective model affects the appearance of the model. What’s more, it will cause a lot of inconvenience to the subsequent researches and treatments. With regard to the problems existing in the hole repairing of 3D scanning model, a hole repairing method based on the improved wavefront method is proposed in the paper. After the initial mesh is formed by virtue of the wavefront method, the curvature can be repaired and the triangle patch can be rotated to a reasonable position. The experimental results show that the algorithm can effectively and quickly generate high-quality closed meshes in the corresponding hole types. Besides, it can accurately restore the geometric features of the hole area while retaining the original information of the model. The algorithm of the paper can be applied in the fields of reverse engineering, archaeology, digital heritage, medical visualization, 3D reconstruction, etc.
