Abstract
A sidewalk information generation device includes a thinning unit configured to perform thinning processing for extracting, from image data indicating an area of a sidewalk, a centerline in a width direction of the area of the sidewalk, a segmentation unit configured to perform segmentation processing for dividing the centerline extracted by the thinning unit in a longitudinal direction to generate a plurality of lines, and a vectorization unit configured to convert each of the plurality of lines generated by the segmentation unit to vector data indicating a coordinate sequence of a plurality of line segments.
Claims10
A sidewalk information generation device comprising:
- a processor;
- and
- a storage medium having computer program instructions stored thereon, when executed by the processor, cause the processor to
- perform thinning processing for extracting, from image data indicating an area of a sidewalk, a centerline in a width direction of the area of the sidewalk;
- perform segmentation processing for dividing the centerline extracted by the thinning unit in a longitudinal direction to generate a plurality of lines;
- and
- convert each of the plurality of lines generated by the segmentation unit to vector data indicating a coordinate sequence of a plurality of line segments.
A sidewalk information generation method performed by a sidewalk information generation device, the sidewalk information generation method comprising:
- performing thinning processing for extracting, from image data indicating an area of a sidewalk, a centerline in a width direction of the area of the sidewalk;
- performing segmentation processing for dividing the centerline that is extracted in a longitudinal direction to generate a plurality of lines;
- and
- converting each of the plurality of lines that is generated to vector data indicating a coordinate sequence of a plurality of line segments.
