Implementation Of An Inexpensive 3d Scanner

Robert Michael Sivley, Western Kentucky University


The purpose of this project was to make 3D scanning technology accessible to the general public at an affordable price. To accomplish this, a scanner was designed that utilized structured-light projection. Coupled with triangulation, this provided an inexpensive, image-based modeling technique. Software was developed to analyze the required images and generate a 3D model. Users can edit analysis parameters during runtime to better optimize results for specific images. The 3D models generated are stored according to the .obj standard and can be opened in any commercial 3D modeling software. Results were positive, but several issues exist with the chosen scanning method; mostly pertaining to image processing. Applications are limited, but results suggest the scanner could be used, with modifications, for low-resolution scans at minimal cost.
