Abstract :
A method for geometrical compensation of distortion of endoscope images is proposed. A model for distortion compensation is built based on a circularly symmetric assumption of distortion, and model parameters are estimated from a distorted image of a grid pattern which consists of several straight lines. Experimental results that demonstrated the effectiveness of this method are shown
