| Research Abstract |
A new three-dimensional (3D) thermography system was developed for analyzing thermal environment of the complex outdoor space containing man-made structures. 3D thermography is realized by combining thermography and three-dimensional geometric information (3DGI).
Until now, it has been difficult to realize a practical 3D thermography system for two reasons. One is that the visual plane of commercially available thermal infrared cameras is limited and the other is that corresponding reference points for thermography and 3DGI are difficult to establish. Thus, a new equipment was developed for obtaining thermography in which the visual plane is extended to a spherical field (4psr) and a new method is proposed for combining it with 3DGI.
The long wave radiant field was evaluated using the spherical thermography technique. Four urban street spaces were chosen for comparison based mainly on differences in upper side condition. Evaluations were conducted during good weather on summer days. The measurement results indicate that long wave radiant field is directly influenced by the design characteristics of the urban space. The present study confirmed the usefulness of spherical thermography for evaluating the long wave radiant field.
