Structured Light 3D Scanner

grabcad

A 3D scanner gathers three-dimensional data such as shape, size, and texture of objects using a 3D scanner. The collected point cloud data can be utilized in numerous ways, including importing it into CAD software for modifications. Building a homemade 3D scanner involves methods like the structured light method. This project's approach utilizes an overhead projector and a machine vision camera for structured light 3D scanning. Engineers may find this reverse engineering technique beneficial. However, version 1 of this homemade 3D scanner faced issues such as flimsy acrylic plates, difficult-to-rotate lead screws, insufficient lens separation, and improper camera angle. Thus, a tripod-based design is being developed for version 2 with updates to address these issues. Some components used in version 1 include an Acer DSV0008 projector, HP 30" monitor, TEC-M55 Telecentric lens, Everest Wired Ultra-Thin Keyboard, and Tockic casters.
