METHOD FOR CONTROLLING AN AERIAL PHOTOGRAPH PLOTTING INSTRUMENT WHICH REVISING A DEFLECTION OF TEMPERATURE VARIATION

摘要

PURPOSE: An aerial photograph plotting instrument for revising a deflection of temperature variation is provided to compensate an error due to temperature variation by controlling the height of a carrier actively. CONSTITUTION: An aerial photograph film is fixed to a carrier(S10). The image of the aerial photograph film is taken by an image pick-up unit. A picture is drawn(S20). The temperature of the aerial photograph film is detected through a temperature detection unit(S30). A controller calculates the height of the image pick-up unit(S40). The image pick-up unit is lifted to the height of the image pick-up unit(S50).
