Vehicle control device, vehicle control method, and storage medium
A vehicle control device according to an embodiment includes an imager configured to image surroundings of a host vehicle, a recognizer configured to recognize a surroundings situation of the host vehicle, a driving controller configured to control one or both of speed and steering of the host vehicle on the basis of a result of the recognition of the recognizer, and a controller configured to control the driving controller on the basis of imaging content of the imager, and the controller performs scanning on an object present around the host vehicle on a two-dimensional image captured by the imager at an angle serving as a predetermined angle upward from left and right lower ends of the two-dimensional image, and sets a point first coming in contact with the object as a ground contact point of the object.
1. A vehicle control device comprising:
an imager configured to image surroundings of a host vehicle;
a recognizer configured to recognize a surroundings situation of the host vehicle;
a driving controller configured to control one or both of speed and steering of the host vehicle on the basis of a result of the recognition of the recognizer; and
a controller configured to control the driving controller on the basis of imaging content of the imager,
wherein the controller performs scanning in oblique direction on an image area enclosed by outlines of an object present around the host vehicle included in a two-dimensional image captured by the imager at an angle serving as a predetermined angle upward from left and right lower ends of the image area, and sets a point first coming in contact with the object as a ground contact point of the object.
2. The vehicle control device according to claim 1 , wherein the controller sets a rectangular area surrounded by the object on the two-dimensional image as the image area, and performs scanning in oblique direction each set rectangular area upward from left and right lower ends of the rectangular area at the angle serving as the predetermined angle, to acquire the left and right ground contact points of the object.
3. The vehicle control device according to claim 2 , wherein the predetermined angle is an angle formed by the lower end of the two-dimensional image captured by the imager and a demarcation line included in the two-dimensional image.
4. The vehicle control device according to claim 3 , wherein the predetermined angle is an angle when demarcation lines of a predetermined area with reference to a position of the demarcation line coming in contact when the lower end of the rectangular area extends in a lateral direction of the two-dimensional image is viewed from a left-right direction of the two-dimensional image.
5. The vehicle control device according to claim 4 , wherein the controller sets the predetermined angle to a fixed value when the angle of the demarcation line with respect to the left-right direction of the two-dimensional image exceeds a threshold value.
6. The vehicle control device according to claim 5 , wherein the fixed value is 45 degrees.
7. The vehicle control device according to claim 1 , wherein the controller corrects a position of the object recognized by the recognizer on the basis of the ground contact point of the object, and controls the driving controller on the basis of the corrected position of the object.
8. A vehicle control method comprising, on a computer:
imaging, by an imager, surroundings of a host vehicle;
recognizing a surroundings situation of the host vehicle;
executing driving control to control one or both of speed and steering of the host vehicle on the basis of a result of the recognition;
controlling the driving controller on the basis of imaging content of the imager; and
performing scanning in oblique direction on an image area enclosed by outlines of an object present around the host vehicle included in a two-dimensional image captured by the imager at an angle serving as a predetermined angle upward from left and right lower ends of the image area, and setting a point first coming in contact with the object as a ground contact point of the object.
9. A computer-readable non-transitory storage medium having a program stored therein, the program causing a computer to:
image surroundings of a host vehicle using an imager;
recognize a surroundings situation of the host vehicle;
execute driving control to control one or both of speed and steering of the host vehicle on the basis of a result of the recognition;
control the driving controller on the basis of imaging content of the imager; and
perform scanning in oblique direction on an image area enclosed by outlines of an object present around the host vehicle included in a two-dimensional image captured by the imager at an angle serving as a predetermined angle upward from left and right lower ends of the image area, and set a point first coming in contact with the object as a ground contact point of the object.
