A New Easy Camera Calibration Technique Based on Circular Points
Inspired by Zhang's work, a new easy technique for calibrating a camera based on circular points is proposed. The proposed technique only requires the camera to observe a newly designed planar calibration pattern (referred to as the model plane hereinafter) which includes a circle and a pencil of lines passing through the circle's center, at a few (at least three) different unknown orientations, then all the five intrinsic parameters can be determined linearly. The main point of our new technique is that it needs to know neither metric measurement on the model plane, nor the correspondences between points on the model plane and image ones, hence it can be done fully automatically. The proposed technique is particularly useful for those people who are not familiar with computer vision. Experiments with simulated data as well as with real images show that our new technique is robust and accurate.
