Abstract :
The relation between the accuracy of calibrated TV camera parameters and the calibration condition is examined by applying a law of propagation, and the optimal calibration condition is proposed where an iterative method is applied to calibrate the parameter values. Furthermore, the variance of the estimated 3D information is determined quantitatively in the case of optimal calibration condition
