Obstruction detection
First Claim
1. A system for a vehicle, the system comprising:
- a camera configured to capture a plurality of image frames from a region outside of the vehicle in a direction of motion of the vehicle, wherein the region outside of the vehicle is beyond an end of the vehicle in the direction of motion;
a processor coupled to the camera and configured to receive the image frames and process the image frames to detect an object obstructing the motion of the vehicle; and
at least one light attached to the vehicle, wherein the at least one light is configured to illuminate the region outside of the vehicle in response to a change in a state of operation of the vehicle,wherein the object is detected based on a comparison of one of the image frames captured before the change in the state of operation of the vehicle and another one of the image frames captured after the change in the state of operation of the vehicle.

Abstract
Systems and methods are provided for obstruction detection for a vehicle. In one implementation, a system mountable in a vehicle may comprise a camera configured to capture a plurality of image frames from a region outside of the vehicle in a direction of motion of the vehicle. The system may also comprise a processor coupled to the camera and configured to receive the image frames and process the image frames to detect an object obstructing the motion of the vehicle. The system may also comprise a light attached to the vehicle, the light illuminating the region outside of the vehicle. The detection of the object may be performed based on a change in illumination between the image frames.

10. A method, comprising:
-
capturing, by a camera, a first image frame from a region outside of a vehicle; changing a state of operation of the vehicle, wherein at least one light is configured to change an illumination of the region outside of the vehicle in response to the change in the state of operation of the vehicle; capturing, by the camera, after the change in the state of operation, a second image frame from the region outside of the vehicle; and comparing the first image frame and the second image frame to detect an object obstructing motion of the vehicle based on the change in the illumination of the region after the change in the state of operation of the vehicle. - View Dependent Claims (11, 12, 13, 14, 15)

16. A system for a vehicle, the system comprising:
-
a camera configured to capture a plurality of image frames from a region outside of the vehicle; and a processor configured to; cause the camera to capture a first image frame; identify a change in a state of operation of the vehicle, wherein at least one light is configured to change an illumination of the region outside of the vehicle in response to the change in the state of operation of the vehicle; cause the camera to capture a second image frame after the change in the state of operation of the vehicle; wherein the at least one light changes the illumination of the region in response to the change in the state of operation of the vehicle after the first image is captured and before the second image frame is captured; compare the first image frame and the second image frame; and detect an object obstructing motion of the vehicle in the region outside of the vehicle based on a result of the comparison. - View Dependent Claims (17, 18, 19, 20, 21, 22)
