Camera Calibration

This new methodology for Explicit Camera Calibration is based on the use of monoplane calibration points, with the advantage that the scale factors are updated during the calibration process and no restrictions occur in terms of the pose of the camera. The parameters are obtained explicitly at different stages using an Iterative Approach. (Iterative Multi-Step Monoplane Camera Calibration)
