经典的航空图像道路中心线提取算法针对非实时应用,计算耗时长,难以满足视觉辅助导航、实时地物识别等应用的要求。在研究了图像中道路法向和等效道路宽度的基础上,建立了近似道路法向和等效道路宽度模型来代替经典道路模型,提出了基于道路中心线的快速提取方法。对比实验的结果说明:快速提取方法和经典方法取得了相近的道路提取效果,计算耗时大大下降,可以满足实时性要求。
經典的航空圖像道路中心線提取算法針對非實時應用,計算耗時長,難以滿足視覺輔助導航、實時地物識彆等應用的要求。在研究瞭圖像中道路法嚮和等效道路寬度的基礎上,建立瞭近似道路法嚮和等效道路寬度模型來代替經典道路模型,提齣瞭基于道路中心線的快速提取方法。對比實驗的結果說明:快速提取方法和經典方法取得瞭相近的道路提取效果,計算耗時大大下降,可以滿足實時性要求。

Aviation image road centerline extraction algorithm was based on the classical non real time applications, long time consuming, difficult to meet the application of visual aided navigation, real-time object recognition and other require-ments. Based on the image method and the equivalent width of the road to the road, a road approximating method and the equivalent width of road model had been set up instead of the classic road model, and a fast extraction method based on the road center line was put forward. The experimental results showed that it achieved similar about road extraction meth-od and classical method, but the computing time had been greatly reduced, it could meet the real-time requirements.
