Build Your Own 3D Scanner: Conclusion http://mesh.brown.edu/byo3d/ SIGGRAPH 2009 Courses Douglas Lanman and Gabriel Taubin This course provides a beginner with the necessary mathematics, software, and practical details to leverage projector-camera systems in their own 3D scanning projects. An example-driven approach is used throughout; each new concept is illustrated using a practical scanner implemented with off-the-shelf parts. The course concludes by detailing how these new approaches are used in rapid prototyping, entertainment, cultural heritage, and web-based applications.

- Build Your Own 3D Scanner 2/18/2009 Thank you for attending the “Build Your Own 3D Scanner” course. We hope that this course has inspired you to construct your own projector-camera systems for 3D photography. In the process of developing this course, we have made our best effort to gather all the software, source code, and practical algorithms you would need to build 3D scanners based on optical triangulation. In particular, we’ve provided MATLAB and C/C++ software libraries, extended from popular sources like the Camera Calibration Toolbox for MATLAB and OpenCV, to allow projector and camera calibration. We look forward to corresponding with attendees as they develop their own systems using the theory and tools developed in this course. In particular, we encourage students to contact us if they have questions about using the software for their own course projects. We’ll update the course website as you send us photos and details of your own DIY projects. For the remainder of the time we have, we’d like to open the floor to questions from the audience.
