説明
Graphic data are transferred to the video-frame memory by a TV camera, and curves are automatically traced to create digital curve data that consist of successive grid points of the video-frame memory with high grey levels corresponding to dark points. The curve data are first fit to a line every small segment, and then approximated by a smooth connection of circular arcs. Contours on a map are processed in this way, and the altitude at an arbitrary point is evaluated by an interpolation. Namely a curve that passes this point and intersects perpendicularly to neighbouring contours is introduced, and the contour values are interpolated, based on the distances to the contours along the curve.
