Filling simple holes by using enhanced advancing front mesh method (EAFM): Application to a real object

Abstract

Nowadays, the physical object can be constructed in digital representation by reverse engineering process. The process started by collecting the point cloud data point from the surface of 3D object. The non-touch approaches from 3D laser scanner are advantageous because of their high scanning speed, high accuracy, real time application, etc. Object complexity such as glossy surface and shining can lead to deficiencies in the quality of data measure using a 3D scanner which leads to missing data and the formation of holes within the constructed 3D model object. A hole is referred to as simple if it does not have feature vertices except other point which have same connection of data points. This paper utilised the advanced front method (AFM) to create triangle into the simple holes area. The paper then improved the hole filling process for simple holes found on a 3D object or real-world object. In this paper, the enhanced method proposed two new AFM methods to the original method. The method was applied to the 3D object and the problem of finding new point for each triangle creation is solved.
