IMAGE QUALTY IMPROVING SYSTEM OF AIRCRAFT IMAGE FOR PRODUCTIVITY AND ACCURACY ON DIGITAL MAP

摘要

PURPOSE: An image quality improving system of aerial photography image for improving the accuracy and productivity of drawing is provided to scan a selected particular part or scan a part except for the selected particular part by minutely adjusting the location of a positive film scanned in the plotter of a drawing process system. CONSTITUTION: When a control unit moves a positive film in X-axis or Y-axis direction, the control unit drives a first and a second Y-axis motor(2040,2070). A first and a second Y-axis pinion gear(2030,2060) are rotated by the drive of the above-mentioned motor. A first and a second Y-axis rack gear(2010,2020) horizontally move respectively in the X-axis or Y-axis direction.
