Abstract: 3D reconstruction using structured light scanning has emerged as an indispensable component within the workflows of numerous engineering fields. Structured light scanning has revolutionised design, analysis, and fabrication processes with its ability to capture detailed surface information and produce high-resolution three-dimensional models. By projecting a known pattern of light onto a subject and analysing the distortions caused by its interaction with the surface, this technique enables the precise reconstruction of complex geometries, allowing engineers to visualise, measure, and manipulate objects with unparalleled accuracy. This paper discusses the development of a low-cost and robust structured light scanning system and evaluates its performance based on vertex quality histogram using Hausdorff distance. It also provides an overview of the basic principles of structured light scanning, emphasising the procedure to achieve good calibration results. Its transformative impact on industries such as manufacturing, architecture, medical imaging, and robotics has enhanced the overall process involved. As structured light scanning continues to evolve and adapt to the ever-changing demands of modern engineering, it is poised to further shape the future of design, analysis, and innovation in various industries.

Keywords: structured light scanning; 3D reconstruction; projector-camera calibration.
