Abstract
The present teaching relates to method, system, medium, and implementations for detecting sensor tampering. Information is received from an inertial measurement unit (IMU) attached to a structure hosting at least one sensor. The information includes one or more measurements associated with the IMU. The at least one sensor is deployed on a vehicle for sensing surrounding information to facilitate autonomous driving. The one or more measurements are analyzed with respect to pre-determined criteria to detect tampering of the at least one sensor. When the tampering is detected, a response is generated to the event.
Claims21
A processor-based method, comprising:
- receiving, from an inertial measurement unit (IMU) attached to a structure that is coupled to at least one sensor and a vehicle, one or more measurements associated with the IMU,
- the at least one sensor configured to sense surrounding information to facilitate autonomous driving:
- analyzing the one or more measurements to detect tampering. of the at least one sensor;
- and
- generating, if the tampering is detected. a response to the tampering.
The processor-based method of claim Wherein the response is used to control performing at least one of:
- triggering an alarm on the vehicle to produce an audio alarm;
- turning on selected sensors deployed on the vehicle to record information associated with the tampering;
- or
- transmitting signals to a remote site via a network connection to report the tampering.
Machine readable and non-transitory medium having information recorded thereon for detecting sensor tampering, wherein the information, when read by the machine, causes the machine to perform:
- receiving, from an inertial measurement unit (IMU) attached to a housing or a sensor rack that is coupled to at least one sensor and a vehicle, one or more measurements associated with the IMU,
- the at least one sensor configured to sense surrounding information to facilitate autonomous driving;
- analyzing the one or more measurements to detect tampering of the at least one sensor;
- and
- generating, if the tampering is detected, a response to the tampering.
The medium of claim 12, wherein
- the state of the vehicle is one of a motion state or a parking state;
- and
- the first measurement corresponds to a vibration measure set to he used to detect tampering if the vehicle is in the parking state.
The medium of claim 13, wherein the information, when read by the machine, further causes the machine to perform:
- analyzing a second measurement from the one or more measurements indicative of a pose of the IMU;
- and
- determining the tampering based on the first measurement and the second measurement.
A system, comprising:
- a first controller configured to receive, from an inertial measurement unit (IMU) attached to a structure that is coupled to at least one sensor and a vehicle, one or more measurements associated with the IMU,
- the at least one sensor configured to sense surrounding information to facilitate autonomous driving, and
- the first controller configured to analyze the one or more measurements to detect tampering of the at least one sensor;
- and
- a second controller operatively coupled. to the first controller, the second controller configured to generate, if the tampering is detected, a response to the tampering.
