摘要: |
为了解决三维城市重建中的建筑物高程提取问题,提出一种折反射全景与遥感图像融合的建筑物高度自动提取方法。该方法分为三步,首先进行折反射全景与遥感图像的配准,然后利用配准结果提取折反射全景图像中建筑物的底部和顶部边界,最后基于边界信息,根据折反射全景成像光路跟踪模型计算建筑物的高度,整个提取过程自动完成。实验结果证明该方法可行且高度提取结果比较准确,对于常见的居民楼,误差基本可控制在4%以下。 |

Abstract: |
A method of automatic building height extraction by Fusing Catadioptric Panoramas and Remote Sensing Images was presented for solving the problem about building height extraction in 3D city reconstruction. The method has three steps. First, images between Catadioptric Panoramas and Remote Sensing were registered. Second, the building in the Catadioptric Panoramas were extracted by using the previous result of image registration, Finally, the building height with catadioptric projection model was calculated based on the information of the top and bottom borderlines. The whole processing of building height extraction was completed automatically. Experiments show that this method is feasible and can obtain a precise result, especially for dwelling houses, error reaches no more than 4%. |
