A Master-Slave Calibration Algorithm with Fish-Eye Correction

Figure 3

Evaluation of the proposed fish-eye correction method. (a) The surveillance scenario used to perform the experimental validation of the proposed approach. The reference object is annotated in yellow while the objects used to perform distortion correction are presented in red. Lines representing the direction of the vanishing points are shown in black color. (b) The height estimation error, in centimeters, when using different fish-eye projections and angles of view to correct the image distortion.
