Abstract
A gesture based authentication system for an autonomous vehicle (AV) uses light detecting and ranging (lidar) to observe a user making a specific gesture and, in response to observing the gesture, authorizes the user to access the vehicle. The authentication system may first identify a human in the vicinity of the AV, and then compare a body position of the identified human to a model trained to determine if a human is performing the specific gesture. If the model determines that the identified human is performing the gesture, the AV authorizes the user to access the vehicle, e.g., to accept a delivery or to ride in the AV.
Claims20
A method of authenticating a user of an autonomous vehicle (AV) comprising:
- receiving a selection of an authentication gesture associated with a user, the authentication gesture selected from a plurality of authentication gestures;
- receiving sensor data describing an environment surrounding the AV, the sensor data comprising data from at least one light detecting and ranging (lidar) sensor;
- identifying, based on the sensor data, the user in the environment of the AV;
- comparing sensor data describing at least one body position of the identified user to a model of a human performing the authentication gesture, the model trained based on sensor observations of a plurality of humans performing the authentication gesture;
- determining, based on the comparison, that the identified user is performing the authentication gesture;
- and
- in response to determining that the identified user is performing the authentication gesture, authorizing the identified user to access the AV.
A system for authenticating a user of an autonomous vehicle (AV) comprising:
- a light detecting and ranging (lidar) sensor configured to collect data describing an environment surrounding the AV;
- and
- a processor configured to:
- receive a selection of an authentication gesture associated with a user, the authentication gesture selected from a plurality of authentication gestures;
- identify, based on the collected data, the user in the environment of the AV;
- select a portion of the collected data, the selected portion describing at least one body position of the identified user;
- compare the selected portion of the collected data describing at least one body position of the identified user to a model of a human performing the authentication gesture, the model trained based on sensor observations of a plurality of humans performing the authentication gesture;
- determine, based on the comparison, that the identified user is performing the authentication gesture;
- and
- in response to determining that the identified user is performing the authentication gesture, authorize the identified user to access the AV.
A system for authenticating a user of an autonomous vehicle (AV) comprising:
- a sensor suite configured to collect data describing an environment surrounding the AV, the sensor suite comprising a light detecting and ranging (lidar) sensor, a camera, and a radar sensor;
- and
- a processor configured to:
- receive a selection of an authentication gesture associated with a user, the authentication gesture selected from a plurality of authentication gestures;
- identify, based on the collected data, the user in the environment of the AV;
- compare sensor data describing at least one body position of the identified user to a model of a human performing the authentication gesture, the model trained based on sensor observations of a plurality of humans performing the authentication gesture;
- determine, based on the comparison, that the identified user is performing the authentication gesture;
- and
- in response to determining that the identified user is performing the authentication gesture, authorize the identified user to access the AV.
