Classification: CPC G  B | IPC B  G

Claim 1:
2. A lane estimation device comprising a processor and a memory connected to the processor, the processor configured to:
acquire image data obtained by imaging a range including a road region in which a moving object is moving, and store the acquired image data in the memory;
read out the image data stored in the memory, recognize a shape indicating the road region from the image data, and calculate, based on the recognized shape indicating the road region, at least one of center-of-gravity coordinates for a diagram indicating the shape, an angle of one vertex of the diagram indicating the shape or an angle of one vertex of a virtual diagram derived from the diagram, and an area of the diagram indicating the shape as a feature value of the road region; and
estimate a lane in which the moving object is moving by determining which threshold value range preset for each lane the calculated center-of-gravity coordinates for the diagram, vertex angle, and diagram area are included in.
