Plastic components play a significant role in conserving and saving energy. Plastic products provide some advantages over metal, including reducing part weight, manufacturing costs, and waste, and increasing corrosion resistance. Environmental sustainability is one of the sustainable development goals (SDGs). Currently, the non-contact computer-aided verification method is frequently employed in the plastic industry due to its high measurement efficiency compared with the conventional contact measuring method. In this study, we proposed an innovative, green three-dimensional (3D) optical inspection technology, which can perform precise 3D optical inspection without spraying anything on the component surface. We carried out the feasibility experiments using two plastic parts with complex geometric shapes under eight different proposed measurement strategies that can be adjusted according to the software interface. We studied and analyzed the differences in 3D optical inspection for building an empirical technical database. Our aim in this study is to propose a technical database for 3D optical measurements of an object without spraying anything to the component's surface. We found that the research results fulfilled the requirements of the SDGs. Our research results have industrial applicability and practical value because the dimensional average error of the two plastic parts has been controlled at approximately 3 µm and 4.7 µm.
塑料部件在节约和节省能源方面发挥着重要作用。塑料制品相对于金属具有一些优势，包括减轻部件重量、降低制造成本和减少浪费，以及提高耐腐蚀性。环境可持续性是可持续发展目标（SDGs）之一。目前，与传统的接触式测量方法相比，非接触式计算机辅助验证方法因其高测量效率而在塑料行业中经常被采用。在本研究中，我们提出了一种创新的绿色三维（3D）光学检测技术，该技术可以在不向部件表面喷涂任何东西的情况下进行精确的3D光学检测。我们使用两个具有复杂几何形状的塑料部件，在八种不同的、可根据软件界面进行调整的测量策略下进行了可行性实验。我们研究并分析了3D光学检测中的差异，以建立一个经验技术数据库。我们在本研究中的目的是提出一个用于对物体进行3D光学测量的技术数据库，且无需向部件表面喷涂任何东西。我们发现研究结果满足了可持续发展目标的要求。我们的研究结果具有工业适用性和实际价值，因为两个塑料部件的尺寸平均误差已控制在约3 µm和4.7 µm。
