Abstract
A method to automate detection of a vehicle light degradation or failure includes generating a distinct pattern to be executed by at least one vehicle light, and sending a command to a light control module operative to cause the at least one vehicle light to emit the distinct pattern. The method continues with extracting features from camera images of the distinct pattern emitted by the at least one vehicle light, and then comparing the features extracted from the camera images with features from the commanded distinct pattern to determine degradation or failure of the at least one vehicle light's state of health.
Claims20
A method to automate detection of a vehicle light degradation or failure comprising:
- generating a distinct pattern to be executed by at least one vehicle light;
- sending a command corresponding to the distinct pattern to a light control module operative to cause the at least one vehicle light to emit the distinct pattern;
- extracting features from camera images of the distinct pattern emitted by the at least one vehicle light;
- and
- comparing the features extracted from the camera images against features from the commanded distinct pattern to determine degradation or failure of a state of health of the at least one vehicle light.
A method to automate detection of a vehicle light degradation or failure comprising:
- determining if conditions for testing a state of health of an at least one vehicle light are not optimal;
- generating a distinct pattern to be executed by the least one vehicle light;
- sending a command corresponding to the distinct pattern to a light control module operative to cause the at least one vehicle light to emit the distinct pattern;
- extracting features from camera images of the distinct pattern emitted by the at least one vehicle light;
- and
- comparing the features extracted from the camera images against features from the commanded distinct pattern to determine degradation or failure of the state of health of the at least one vehicle light.
