Evaluation of Effect of 3D Scanning on Building Models in Reverse Engineering

With the advancement of technology, 3D modeling tools and software have become increasingly popular. However, the cost of scanning devices used in reverse engineering also increases as the precision requirements rise. This phenomenon has led to increased time and cost for small and m Edium-sized enterprises (SMEs) that rely on rapid prototyping in the early stages of product development and DIY enthusiasts seeking to bring their creative ideas to life. This study aims to analyze the advantages and disadvantages of using a structured light scanning method combined with triangulation for 3D scanning and evaluate whether sufficient point cloud data can be collected for subsequent rapid reverse modeling. Two products with d different shapes and profiles will be selected as the subjects of the scanning evaluation experiment. The experimental results reveal that the 3D scanner combining structured light scanning and triangulation is influenced by the complexity of the scanned object’s shape. When capturing point cloud data for more complex objects, it may result in numerous damaged surfaces and noise, which requires repair using software such as meshlab.
