直接线性变换在建筑物比高求解中的应用

The application of DLT in the solving process of building height measurement

高度信息作为人工地物的重要属性信息,在军事和民用上都具有很高的利用价值。针对人工地物高度提取的发展现状及存在的主要问题,本文对单张航片利用直接线性变换结合DEM确定人工地物比高方法的原理和技术进行了研究,并进行了实验,验证了方法的可行性。

The height information is important for cultural features at practice. According to the analysis of the latest technology on the height measurement of cultural features, this paper describes the method which uses the DLT and the DEM in the process of the cuhural feature height measurement based on the single aerial photo. Results of the experiment show that the method is effective and robust.
