Abstract
Systems, methods, and devices for detecting brake lights are disclosed herein. A system includes a mode component, a vehicle region component, and a classification component. The mode component is configured to select a night mode or day mode based on a pixel brightness in an image frame. The vehicle region component is configured to detect a region corresponding to a vehicle based on data from a range sensor when in a night mode or based on camera image data when in the day mode. The classification component is configured to classify a brake light of the vehicle as on or off based on image data in the region corresponding to the vehicle.
Claims20
A method comprising:
- selecting a night mode or a day mode based on a pixel brightness in an image frame;
- detecting an image region corresponding to a vehicle based on range sensor data when in the night mode or based on camera image data when in the day mode;
- and
- classifying a brake light of the vehicle as on or off based on image data in the image region corresponding to the vehicle.
A system comprising:
- a range sensor;
- a camera;
- and
- one or more processor programmable to execute instructions stored in non-transitory computer readable storage media, the instructions comprising:
- receiving an image frame from the camera;
- selecting a night mode or a day mode based on a pixel brightness in the image frame;
- detecting an image region corresponding to a vehicle based on range sensor data received from the range sensor when in the night mode or based on camera image data received from the camera when in the day mode;
- and
- classifying a brake light of the vehicle as on or off based on image data in the image region corresponding to the vehicle.
The system of 9, wherein the instructions further comprise determining at least one region of interest within the image region that corresponds to a brake light of the vehicle based on the converted range sensor data when in the night mode or the converted camera image data when in the day mode.
Non-transitory computer readable storage media storing instructions that, when executed by one or more processors, cause the one or more processors to:
- select a night mode or a day mode based on a pixel brightness in an image frame;
- detect an image region corresponding to a vehicle based on range sensor data when in the night mode or based on camera image data when in the day mode;
- and
- classify a brake light of the vehicle as on or off based on image data in the image region corresponding to the vehicle.
