Road Extraction from images using Template Matching

摘要

The invention here as to a method for extracting the road in order to produce a map from the images recorded in the satellite or aircraft, extracting the road from more specifically the taken image, by using a template (template) matching (matching) of the image It relates to a method of extracting the road.; The present invention provides a method for extracting the road from the image taken by the satellite or aircraft, when the initial input coordinates is selected, the first step of calculating the orientation of the selected initial input coordinates; A second step of generating the template window tilted by the calculated azimuth around the initial input coordinates; A third step of generating an initial window to move to the object orientation direction of the input coordinates from the created template window; A fourth step of performing the template matching window around the initial purpose of the generation of calculating the center coordinates and the orientation of the new window; A fifth step of repeatedly performing the step 4 until the processing is completed for all the images to create a new object window to move to a new azimuth direction of said calculated from the calculated center point; And by connecting the center point obtained from the image and a sixth step of generating the road.
