Vehicle control device
View Patent ↗According to one embodiment, by way of example, a vehicle control device includes: an acquisition unit configured to acquire map data indicating an absolute azimuth of a linear road surface sign disposed on a road surface on which a vehicle travels, and image data obtained by imaging surroundings of the vehicle with a vehicle-mounted camera included in the vehicle; and a correction unit configured to detect the road surface sign from the acquired image data, calculate a relative azimuth of the road surface sign with respect to the vehicle on the image data, calculate a shift of an azimuth in which the vehicle moves based on the calculated relative azimuth and the absolute azimuth of the detected road surface sign indicated by the map data, and correct the azimuth in which the vehicle moves based on the calculated shift.
1. A vehicle control device comprising:
at least one processor configured to implement:
n acquisition unit configured to acquire map data indicating an absolute azimuth of a linear road surface sign disposed on a road surface on which a vehicle travels, and image data obtained by imaging surroundings of the vehicle with a vehicle-mounted camera included in the vehicle; and
a correction unit configured to detect the road surface sign from the acquired image data, calculate a relative azimuth of the road surface sign with respect to the vehicle on the image data, calculate a shift of an azimuth in which the vehicle moves based on the calculated relative azimuth and the absolute azimuth of the detected road surface sign indicated by the map data, and correct the azimuth in which the vehicle moves based on the calculated shift.
2. The vehicle control device according to claim 1 , wherein the road surface sign is a roadway outside line drawn on the road surface on which the vehicle travels.
3. The vehicle control device according to claim 1 , wherein the road surface sign is a linear azimuth marker drawn on the road surface on which the vehicle travels.
4. The vehicle control device according to claim 1 , wherein the road surface sign is a pedestrian crossing that is disposed on the road surface on which the vehicle travels.
5. The vehicle control device according to claim 1 , wherein the road surface sign is a stop line that is disposed on the road surface on which the vehicle travels.
6. The vehicle control device according to claim 1 , wherein the road surface sign is a linear road surface sign different from a parking partition line indicating a parking frame.
7. The vehicle control device according to claim 1 , wherein the correction unit detects the road surface sign from the image data obtained by the vehicle-mounted camera at a predetermined position.
8. The vehicle control device according to claim 7 , wherein the correction unit detects the road surface sign from the image data that is obtained by the vehicle-mounted camera at a time when the vehicle stops at the predetermined position.
