Abstract
Systems and method are provided for controlling a vehicle. In one embodiment, a determination is made that a traffic control person and a traffic control sign are present within the environment of the vehicle based on sensor data, such as optical camera data. The position and orientation of the traffic control sign relative to the traffic control person is determined, e.g., via lidar sensor data, and the validity of the traffic control person and the traffic control sign is determined based on the position and orientation of the traffic control sign.
Claims20
A traffic control detection method comprising:
- receiving sensor data relating to an environment associated with a vehicle;
- determining that a traffic control person and a traffic control sign are present within the environment based on the sensor data;
- determining a position and an orientation of the traffic control sign relative to the traffic control person;
- and
- determining whether the traffic control person and the traffic control sign are valid based on the determined position and orientation.
A system for controlling a vehicle, comprising:
- a traffic control person detection module, including a processor, configured to receive sensor data relating to an environment associated with a vehicle and determine that a traffic control person and a traffic control sign are present within the environment based on the sensor data;
- and
- a position determination module configured to determine a position and an orientation of the traffic control sign relative to the traffic control person, and confirm that the traffic control person and the traffic control sign are valid based on the determined position and orientation.
An autonomous vehicle, comprising:
- at least one sensor that provides sensor data;
- and
- a controller that, by a processor and based on the sensor data:
- receives sensor data relating to an environment associated with a vehicle;
- determines that a traffic control person and a traffic control sign are present within the environment based on the sensor data;
- determines a position and an orientation of the traffic control sign relative to the traffic control person;
- and
- confirms a validity of the traffic control person and the traffic control sign based on the determined position and orientation.
