- Abstract
Three-dimensional (3D) scanning has been used widely for prototyping. However, sometimes the object is not successfully reconstructed into a 3D model. One of the important parameters in the mesh generation is the radius threshold. This study aimed to investigate the effects of the radius threshold on the mesh generation in terms of mesh quality, percentage of generated faces, and the processing time. Two methods, i.e., Delaunay and Alpha-shapes, were implemented for the comparison. A Kinect sensor was utilized for the 3D scanning. Skanect and Matlab were employed for point cloud capturing and data processing, respectively. As a result, the mesh quality and percentage of the generated faces were influenced by the radius threshold even though the two methods have different trends. The effect of the radius threshold on the processing time can be neglected. Generally, Delaunay resulted in lesser processing time compared to Alpha-shapes.
