| title | Camera Calibration |
It is quite common for projects to involve vision systems, but despite this most teams working with cameras ignore the basic advantages of calibrating a camera properly. Not only does a good calibration lead to better quality of data in form of images captured but also reduces overall errors in the vision the system, a properly calibrated camera helps avoid unnecessary delays due to radiometric and geometric errors.
Listed below are a few good places to get started on camera calibration.
- Quick intro. and overview: https://www.cs.umd.edu/class/fall2013/cmsc426/lectures/camera-calibration.pdf
- A comprehensive guide: http://www.cs.rutgers.edu/~elgammal/classes/cs534/lectures/CameraCalibration-book-chapter.pdf
- Chapter 2 in this book: http://szeliski.org/Book/drafts/SzeliskiBook_20100903_draft.pdf (I would highly recommend this book, above all)
