When performing image measurement by infrared rays, a wavelength range of 3 to 5 μm or 8 to 13 μm is normally used to avoid atmospheric absorption due to remote measurement. In case of outdoor measurement of buildings, however, there appear effects of insolation and sky reflection.
This time, we made and evaluated a prototype of an infrared camera with the range of 6.5 to 8.6 μm, and confirmed that the effects of insolation and sky reflection could be reduced. It was also confirmed that correction was possible by obtaining the temperature and humidity of outside air and the measuring distance, although there is an effect of absorption by water vapor in this range.
