本文介绍了一套完整的石材工具三维模型的建立过程，包括扫描、数据采集、表面重建和孔洞填充。扫描数百或数千个小物体的过程非常耗时。我们独创的3D激光扫描仪优化了扫描过程，并通过同时对许多小物体进行四个方向的扫描来显著缩短时间。为了重建石材工具的表面，扫描点云处理的一种新的三角剖分方法，保持锋利的边缘的属性。我们的方法是基于一个基于投影的方法，其中点被区分成相邻层的点云切片方法进行单独重建。此外，我们介绍了一个简单的孔洞填充算法的模型的网格完成。我们的方法的主要优点是重建许多小物体的速度和效率。
In this paper, we present a whole procedure for constructing 3D models of stone tools including scanning, data acquisition and surface reconstruction with hole-filling. The process of scanning hundreds or thousands of small objects is time consuming. Our original 3D laser scanner optimizes the scanning process and reduces time significantly by four directional scanning of many small objects simultaneously. To reconstruct surface of stone tools, the scanned point clouds are processed with a new triangulation method that preserves the properties of sharp edges. Our approach is based on a projection based method in which points are distinguished into neighboring layers with a point cloud slicing method to be individually reconstructed. In addition, we introduce a simple hole-filling algorithm for mesh completion of models. The main advantages of our approach are speed and efficiency for reconstruction of many small objects.
