A method and device for automatically identifying a point of interest (e.g., the deepest or highest point) on a viewed object using a video inspection device. The method involves placing a first cursor on an image of the object to establish a first slice plane and first surface contour line, as well as placing another cursor, offset from the first cursor, used to establish an offset (second) slice plane and an offset (second) surface contour line. Profile slice planes and profile surface contour lines are then determined between corresponding points on the first surface contour line and the offset (second) surface contour line to automatically identify the point of interest.
