Urban Road Network Eztraction from Spaceborne SAR Image
A two-step method is developed for the extraction of road network from spaceborne SAR image: road candidates detection and connection. In the road candidates detection,classification of fused infrared and microwave SAR images effectively reduces the noise in the edge detection, and also well removes possible confusion of no-road objects,I. e. Linearly-featured rivers in the edge image. Possible road candidates are further processed using the morphological thinning algorithm. Road candidates connection is carried out hierarchically according to road models we established. Finally, the main road network is established from the SAR image successfully. As an example,using the ERS-2 SAR image data, automatic detection of main road network in Shanghai Pudong area is presented.
