Abstract :
A method for calibrating ultrasound and video sensors in the hostile underwater environment is presented. It yields sufficient accuracy to allow transformation of image data in one sensor´s image plane to the baseframe, and from there into the other sensor´s image plane, a prerequisite for any form of sensor fusion. The feasibility of automatic segmentation of underwater video scenes in combination with sparse ultrasound data has been demonstrated by experiment
