Development of an evaluation technique for heat island phenomenon and open space effect by using high resolution thermo graph data

1.夏季热像资料的获取：以南开南坝站为中心，用直升机对南开南巴站东西两个方向2.5公里范围内2.0公里范围内的可见光进行摄影，用30分钟的时间拍摄一幅热图，将拍摄后的每一幅动画所拍摄的画面在计算机上进行拼接合成，生成单张可见光图片和热图。图像处理和测量将热图像形成地理信息系统数据，在计算机上进行可见光和热红外光图像的合成，并对其进行处理，使其能够与地表成分形成对比。结果，在灌木区和乔木植被区，地表温差不大。在灌丛乔木植被杂乱区，地表温差在平均种植区显着。

1. Acquisition of the heat image data of a summerPhotography of the visible light of the range of 2.0km of 2.5km of north-south x east and west centering on the Nankai Namba station and a heat picture was performed using the helicopter from 11:00 on August 3, 2006 in 30 minutes.Mosaic composition of the capture picture captured from each animation was carried out on the computer after photography, and the visible light picture of one sheet and the heat picture were created.2. Image processing and measurementThe heat picture was formed into GIS data, performed composition of visible light and a heat infrared light picture on the computer, and it processed it so that contrast with a surface component might be possible.As a result, in the shrubbery region and the arboreal vegetation region, it became clear in that there is no big surface temperature difference. In a shrubbery arboreal vegetation jumble region that a surface temperature difference significant in the average planting region.
