SYSTEM FOR AUTOMATIC ADJUSTING SHOOTING RATIO OF GENERAL MAP FOR MAKING IMAGE

摘要

PURPOSE: A spatial image drawing correction system is provided to improve work efficiency by photographing a flank image and a plane image of a feature in the same magnification, and by photographing each subject in an adjusted shooting ratio. CONSTITUTION: The lower part of a vertical rod(800) is fixed to one of two fixtures(113,113'). The vertical rod performs as a guide role. A cylindrical guider(810) is ascended and descended along the vertical rod. Therefore, the left and the right sides of a pressure bar(116) are evenly ascended and descended. A friction reduction member is installed on the both ends of the pressure bar. The friction reduction member reduces the frictional resistance with guides(115,115').
