摘要: Over the last decade, digital photography has entered mainstream. Inexpensive, miniaturized cameras are now routinely included in consumer electronics. Digital projection is poised to make a similar breakthrough, with variety of vendors offering small, low-cost projectors. As result, active imaging topic renewed interest computer graphics community. In particular, homemade 3D scanners within reach students and hobbyists modest budgets. This course provides beginners mathematics, software, practical details they need leverage projector-camera systems their own scanning projects. An example-driven approach used throughout; each new concept illustrated using scanner implemented off-the-shelf parts. The concludes by detailing how these approaches rapid prototyping, entertainment, cultural heritage, web-based applications.
