This paper investigates the characteristics of thermal image which has responsibility in 8 to 14V m band (Band A) , in 6.5 to 8.6 μm band (Band B) and in 3 to 5 μm band (Band C). Experiment was carried out at the residential area on a summer clear sky day. Followings were obtained by experimental results. 1) The temperature of roof tile and aluminum sheet in Band A were measured lower than actual temperature by some degree based on effect of sky radiation. 2) The amount of atmospheric effect in Band B was estimated about 6 to 10K when radiant temperature of measured objects were 20K higher than atmosphere. 3) Acceptable measurement accuracy in Band B were limited within 200m in mid-latitude summer, and within 800m in the winter by the difference between atmospheric corrections and measurement errors. We proposed algorithm to measure radiant temperature of glass based on above investigations. Effectiveness of the proposed algorithm was verified by experimental results.
