Camera calibration and 3D reconstruction (calib3d module)

Although we got most of our images in a 2D format they do come from a 3D world. Here you will learn how to find out from the 2D images information about the 3D world.

• Camera calibration with square chessboard

  Compatibility: > OpenCV 2.0

  Author: Victor Eruhimov

  You will use some chessboard images to calibrate your camera.

• Camera calibration With OpenCV

  Compatibility: > OpenCV 2.0

  Author: Bernát Gábor

  Camera calibration by using either the chessboard, circle or the asymmetrical circle pattern. Get the images either from a camera attached, a video file or from an image collection.

• Real Time pose estimation of a textured object

  Compatibility: > OpenCV 2.0

  Author: Edgar Riba

  Real time pose estimation of a textured object using ORB features, FlannBased matcher, PnP approach plus Ransac and Linear Kalman Filter to reject possible bad poses.
