Abstract
The present invention comprises a system and a computer-implemented method designed for measuring the visible colon surface area that has been seen from a colonoscope, and for displaying the results of the measurement. The method estimates the orientation of the camera of the colonoscope, estimates the travel distance of the scope camera from the axial vector lengths coming from or headed towards the focus of expansion point, and visualizing the percentage of the visible surface of the entire colon.
