Abstract
A camera system has a neural network for calibration of image distortion. The neural network learns the conversion from image coordinates with distortion to image coordinates with substantially reduced distortion, whereby the neural network provides image coordinates having substantially reduced distortion. In a learning process of the neural network, a relatively simple camera model is used to provide an instruction signal to the neural network according to sample data provided from the real camera.
