Abstract
A perception module receives frames of data from sensors onboard a vehicle and identifies objects surrounding the vehicle based on the data. A fault detection module determines semantic information associated with the data, generates a score for each of the identified objects based on a correlation of each of the identified objects with the semantic information, and generates a score for the frames based on the scores for the identified objects. The fault detection module determines that the perception module: is operating normally in response to the score for the frames being less than a first threshold, has a fault in response to the score for the frames being greater than a second threshold, and needs inspection in response to the score being between the first and second thresholds.
