Device and method for providing information for vehicle using road surface

A device for providing information for a vehicle, the device comprising:

• an object recognition circuit configured to take a front image of the vehicle and to recognize an object located outside the vehicle;
• a processor configured to recognize a road surface as a road irradiation area, a sidewalk irradiation area, and a boundary area between the road irradiation area and the sidewalk irradiation area, based on the front image, and to generate a driving information image and a walking information image based on the front image;
• and
• an image output circuit configured to irradiate the driving information image adjusted to a size corresponding to the road irradiation area to the road irradiation area, and to irradiate the walking information image adjusted to a size corresponding to the sidewalk irradiation area to the sidewalk irradiation area,
• wherein a background color of the driving information image in the road irradiation area and a background color of the walking information image in the sidewalk irradiation area are different,
• wherein the device is included in the vehicle, and
• wherein the object recognition circuit is further configured to recognize a recessed obstacle of the road surface, and the image output circuit is further configured to output the driving information image for dividing the recessed obstacle into a plurality of areas and mapping the divided obstacle with at least two colors, wherein the plurality of areas include a central area and an outer area.
