More Information
Summary:The invention discloses a building shadow automatic recognition and model covering method, and the method comprises the steps: the extraction and optimization of shadow and other parameters, the calculation and statistic analysis of a building height, the verification of the precision of a height extraction result, and the matching obtaining from a database. The method is high in calculation precision, can reach the precision: less than 2m (the height of one floor), and especially play a big role in actual prevention and reduction of natural disasters. 本发明公开了种建筑阴影自动识别与模型覆盖方法，包括步骤：阴影等参数的提取和优化、建筑物高度的计算和统计分析、高度提取结果的精度验证以及从数据库获取匹配。本发明计算精度高，能够达到精度小于2m(层楼高度)，尤其在实际的防灾减灾方面，起到非常大的作用。
