Abstract
A steering angle detection assembly for measuring a steering angle of an autonomous vehicle is provided. The steering angle detection assembly includes at least one camera, at least one marker, and one or more processors in communication with at least one memory device. The steering angle detection assembly is operable to cause the at least one camera to capture one or more images of the marker. The steering angle detection assembly is operable to determine a position of the at least one marker in the one or more images and determine a steering angle of the autonomous vehicle.
Claims20
A steering angle detection assembly for measuring a steering angle of a vehicle, the steering angle detection assembly comprising:
- a camera configured to capture one or more images of an angle marker positioned on a tie rod of a vehicle, the camera configured to be mounted on the vehicle at a location stationary relative to an axel of the vehicle;
- at least one memory device;
- and
- at least one processor in communication with the at least one memory device, the at least one processor programmed to:
- receive a first image of the angle marker;
- compare the first image with a reference image of the angle marker;
- determine a position of the angle marker based on comparison of the first image with the reference image;
- determine a steering angle based at least in part on the position of the angle marker;
- and
- output the steering angle.
A method of measuring a steering angle of a vehicle, the method comprising:
- receiving one or more images of an angle marker positioned on a tie rod of a vehicle, the one or more images captured by a camera, the camera configured to be mounted on a vehicle at a location stationary relative to an axle of the vehicle;
- comparing a first image of the one or more images with a reference image of the angle marker;
- determining a position of the angle marker based on the comparison of the first image with the reference image;
- and
- determining a steering angle based at least in part on the change in position of the angle marker.
One or more non-transitory machine-readable storage media for measuring a steering angle of a vehicle, the one or more non-transitory machine-readable storage media comprising a plurality of instructions stored thereon that, in response to being executed, cause a system to:
- receive one or more images of an angle marker;
- compare a first image of the one or more images with a reference image of the angle marker;
- determine a position of the angle marker based on the comparison of the first image with the reference image;
- and
- determine a steering angle based at least in part on the position of the angle marker.
