<p>A system for photographing surfaces of solar cell modules of a photovoltaic power generation facility according to an embodiment of the present invention comprises: an unmanned aerial vehicle to fly in the air above a photovoltaic power generation facility along a prescribed route; and a photographing device mounted on the unmanned aerial vehicle to photograph a surface image of solar cell modules. The photographing device adjusts a photographing angle to satisfy the equation,α+β= 90°, whereαis an angle formed between a photographing direction of the photographing device and a line in a perpendicular direction to the ground andβis an angle formed between the solar cell module and the line in the perpendicular direction to the ground to photograph a surface of the solar cell module. And, a target solar cell module is photographed from a photographing location corrected to a normal line to a center of the target solar cell module. According to an embodiment of the present invention, the corrected photographing location is a location horizontally moved by a distance, d[=(H-h)·tanα], from a location vertically above the target solar cell module towards the normal line drawn from the center of the target solar cell module (H is an altitude of the unmanned aerial vehicle, and h is a center height of the target solar cell module). The photographing device comprises an infrared camera to generate a thermo-graphic image.</p> |
