Conversion from raster map to vector map

摘要

For converting raster image map in vector image map, the method implemented by a computer includes receiving an electronic raster image showing the indoor map building structure. The method also includes indoor map to determine whether the line map. If it is not in the line map, the indoor map is converted to a line map. Next, to produce a raster image electronic raster image is processed in the processing has been an indoor map. The method, then, in order to generate an electronic vector image including indoor map building structure, and extracts the vector line from the processed raster image.FIELD 1
