Image processing for vehicle control
First Claim
Patent Images
1. A vehicle comprising:
- a sensor configured to detect objects in the vehicle'"'"'s surroundings, the sensor being associated with a range;
a camera configured to capture a first image of a scene of at least a part of the vehicle'"'"'s surroundings and a second image overlapping at least a part of the scene of the first image;
a memory; and
a processor coupled to the memory, the sensor, and the camera, the processor being configured to;
determine, based on the vehicle'"'"'s pitch, a point P on a visual horizon in the first image;
process the first image and the second image to determine distance between the vehicle and an object that is depicted in the first image above and beyond the point P; and
change at least one of a speed of the vehicle and a heading of the vehicle when it is determined that the distance between the vehicle and the object is less than the range of the sensor.

Abstract
A method is provided for processing an image in which only parts of the image that appear above a point on a horizon line are analyzed to identify an object. In one embodiment, the distance between the object and a vehicle is determined, and at least one of the speed and direction of the vehicle is changed when it is determined that the distance is less than the range of a sensor. The method for processing images is not limited to vehicular applications only and it may be used in all applications where computer vision is used to identify objects in an image.

7. A system comprising:
-
a camera configured to capture a first image and a second image; a sensor configured to sense the pitch of the camera; a processor coupled to the camera and to the sensor, the processor being configured to; select an object that is depicted in the first image based on the object being depicted above and beyond a point P on a visual horizon in the first image, the point P being determined by the processor based on signal from the sensor that senses the pitch of the camera; and process the first image and the second image to determine a distance between the camera and the reference object; receive input from a second sensor having a range; determine a geographic location of the vehicle based on the received input; change at least one of a speed of a vehicle and a heading of the vehicle when it is determined that the distance between a vehicle and the object is less than the range of the second sensor. - View Dependent Claims (8, 9, 10, 11)

12. A method comprising:
-
controlling operation of a vehicle with a first control strategy; capturing, by a camera, a first image of a scene at least part of the vehicle'"'"'s surroundings and a second image overlapping at least a part of the scene of the first image; and processing the first image and the second image to determine a distance between the vehicle and an object appearing above and beyond a point P on a visual horizon in the first image, wherein; (i) the point P is determined based on the pitch of the vehicle, and (ii) the object is selected based on the object being depicted, at least in part, above the point P in the image. - View Dependent Claims (13, 14, 15, 16, 17)
