A Fast Calibration Algorithm Based on Vanishing Point for Scene Camera
A fast and simple calibration method based on vanishing point is carried out to overcome the disadvantage of low efficiency and operation problems which the traditional calibration methods based on standard calibration field has. Focal length and rotation matrix can be calculated by the information of two sets of parallel lines, then translation vector is obtained by the space length and image coordinates of a straight line derived from the origin. The results of experiment indicate the simplicity of this method. At the same time the efficiency is improved with satisfying calibration accuracy in practical application.
