Abstract

The invention discloses a road detection method based on synthetic aperture radar, which is suitable for the field of image processing and solves the defects of high time-consuming, high false alarm and low precision of the existing road detection. The method includes: performing overlapping blocks on the obtained original image to obtain multiple sub-images; performing category classification on the multiple sub-images, the category of the category includes roads and non-containing roads; performing road detection on the sub-images under the category containing roads ; Splice the detected sub-images to obtain the road detection result. The invention is applied to high-resolution SAR image processing.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a road detection method based on synthetic aperture radar. Background technique [0002] Synthetic Aperture Radar (SAR) is a high-resolution imaging radar with all-weather and all-time data acquisition capabilities and the ability to penetrate ground objects. SAR is widely used in the military to provide reconnaissance and target detection information for military operations. At the same time, it also has a large number of civil applications in meteorology, terrain, road detection, and disaster monitoring. [0003] The main task of road detection is to determine the position and shape of the road, and realize the separation of the road and the image background. With the explosive growth of image information, the difficulties of road detection mainly include: (1) the image scene is becoming more and more complex, and the amount of data to be processed is increasing; (2) the detail...
