Abstract

The application of 3D scanner technology among industrial practitioner in Indonesia and Malaysia is still at the beginning stage. In contrast, this technology has been adapted mostly by growing countries such as China, Korea, US and Germany. The 3D scanner technology is mainly implemented in manufacturing, aerospace and medical industries to improve the reverse engineering process. Due to the high cost of 3D scanner available in the market, a cost-effective 3D scanner is needed to be developed. Therefore, the objective of this project is to develop a low-cost 3D scanning setup by using open-sources software to create a mesh of a small-scale object for 3D scanning and 3D mesh processing. In this project, triangulation technique was applied to capture the object surface. Screened Poisson Surface Reconstruction techniques was utilized to improve the uncomplete and uneven surface mesh. In order to test the setup, 3D scanning was conducted on 4 different objects with different colours and surface finish. The scanning results using the proposed method produced a good 3D mesh with less noise and less uncomplete surface. It is observed that colour differences affect the mesh result. In addition, the technique also able to reduce the measurement error in the mesh.
