Above, orthophotos of the west facade of the Paris town hall built from 295 IRT (thermal infrared) and 440 RGB images. Experimentation aimed at qualifying the good photogrammetric restitution from a terrestrial capture and subsequently, accuracy of the temperatures measured on the final radiometric orthophoto.
