%X Camera calibration has been attracting a lot of attentions in computer vision field these days, for it is a necessary step when recovering 3D shape from its 2D images. All methods for calibration can be classified into traditional ones or selfcalibration ones. The main difference between them is that traditional methods need known calibration objects while self-calibration ones do not. The advantage of self-calibration makes a number of researchers studied on it. Hundreds of approaches have been proposed each year. However, most of these methods failed to get the parameters we want simply or failed to keep robust. The approach we proposed here enjoys not only simplicity but also robustness as well, for the reason that we induce the scene information to do calibration. The feature of vanish point of parallel lines has been well used, and experiment results showed that our approach is feasible and effective.
