Over the last decade, digital photography has entered the mainstream with inexpensive, miniaturized cameras for consumer use. Digital projection is poised to make a similar breakthrough. In particular, low-cost homemade 3D scanners are now within reach. This book gives beginners the necessary mathematics, software, and practical details to leverage projector-camera systems in their own 3D scanning projects. Featuring an example-driven approach, the text illustrates each new concept using a practical scanner implemented with off-the-shelf parts. It shows how these new approaches are used in rapid prototyping, entertainment, cultural heritage, and web-based applications.
