摘　　要：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投影误差确定人工地物比高和利用共线条件方程确定人工地物比高两种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 information of cultural features. It has a very important value in use. According to the analysis of the latest technology on the height measurement of cultural features, this paper describes two methods of the cultural feature height measurement based on the single aerial photo, one method uses the conception of projection error, the other one uses the collinear equation. Results of the experiment show that the two methods are all effective.
