Classification: CPC G  B | IPC B  G

Claim 0:
1. A method, comprising:
obtaining, by a device, a plurality of frames of image data, location data, and sensor data associated with a vehicle;
determining, by the device and for each frame of the plurality of frames, a probability that each frame of the plurality of frames that includes an image of a stop sign is relevant to the vehicle;
determining, by the device, a longest sequence of consecutive frames of the plurality of frames for which the probability satisfies a probability threshold;
determining, by the device, a maximum probability associated with a frame included in the longest sequence of consecutive frames;
determining, by the device and based on the location data, a series of speeds of the vehicle;
determining, by the device, a time delay that, when applied to the location data, results in a maximum correlation between the series of speeds and the sensor data;
aligning the location data with the sensor data and the image data based on the time delay;
determining, by the device, a time window based on a time associated with the frame associated with the maximum probability;
identifying, by the device, a portion of the location data and a portion of the sensor data associated with the time window based on aligning the location data with the sensor data and the image data;
determining, by the device, an occurrence of a stop sign violation based on the probability, the portion of the location data, and the portion of the sensor data;
determining, by the device, a type of the stop sign violation; and
performing, by the device, one or more actions based on the type of the stop sign violation.
