AERIAL PHOTOGRAPHY PLOTTING INSTRUMENT HAVING HORIZONTALITY SENSOR AND METHOD USING THE SAME

摘要

PURPOSE: A drawing device containing a horizontal sensor is provided to reflect the light injected from a light emission sensor toward a light receiving sensor, thereby facilitating the horizontal sensing by the measured information. CONSTITUTION: A drawing device comprises the following details: An aerial photo carrier(100) comprises a left carrier module and a right carrier module. A photographing unit(150) is installed on the upper side of the aerial photo carrier, images a positive film, and outputs to an outside. A driving unit(160) comprises a guide rail fixed perpendicularly in the aerial photo carrier and a linear motor guided by the guide rail, getting on and off by the driving. A horizontal sensor(200) sensors the horizontal relying on the left and right tilt between the left carrier module and the right carrier module.
