城市绿化遥感遮蔽校正模型研究

Study on a Correction Model for Defiladed in Urban Virescence Using Remote Sensing Data

遮蔽是大比例尺城市绿化航空遥感调查中存在的一种普遍现象,它直接影响城市绿化遥感调查的结果和城市绿化数据库的准确性.根据航空摄影中心投影成像方法的特征,对城市居住小区的遮蔽现象进行了研究,建立了具有可操作性的居住区面积遮蔽和绿化遮蔽校正模型,并进行了样区比较试验研究.研究结果表明提出的校正模型可以大幅度地提高居住区绿化数据的可靠性.

Hide from view is a kind of pervasive phenomena in large scale image for virescence remote sensing survey in the city. It affects the results of survey and veracity of database for virescence remote sensing. Based on the character of center projection of aerial photography, the phenomena of hide from view, which main contained in habitation section, is studied. The correction model is developed for virescence defilade area in the urban habitation section. At last, a compare test is completed for samples using the model. The results show that the model may improve accuracy of virescence data in habitation section.
