摘要
在对形态学滤波和区域生长算法研究的基础上,通过对桥梁的特点进行分析,提出一种基于形态学滤波和区域生长算法的滤波结果的差异进行桥梁探测的算法。算法不受桥梁形状的影响,桥梁可分叉、无需平行和等宽,甚至在部分桥梁数据不完整的情况下也有效。通过3个不同场景的桥梁实例验证算法的正确性。
Through the research on morphological filter and regional growing, a method of bridge extracting is proposed based on difference between above filtering methods. Combining the characteristics of bridges, the bridges can be extracted from the difference of filtered DEM. The proposed method is adaptable to different bridge designs. Therefore, bridges need not parallel edge or uniform width. Furthermore, a bridge can split into parts, and a bridge can be part of the whole bridge, etc. Three different bridges are conducted to demonstrate the efficiency of the proposed method.
