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:
- calculating an average pixel brightness of a plurality of pixels in an upper region of an image;
- determining whether the average pixel brightness exceeds a threshold value;
- extracting a feature map from the image in response to determining the average pixel brightness exceeds the threshold value;
- and
- determining whether a region of interest identified in the feature map comprises a depiction of a brake light of a vehicle.
A system comprising one or more processors that execute instructions stored in non-transitory computer readable storage medium, the instructions comprising:
- calculating an average pixel brightness of a plurality of pixels in an upper region of an image;
- determining whether the average pixel brightness exceeds a threshold value;
- extracting a feature map from the image in response to determining the average pixel brightness exceeds the threshold value;
- and
- determining whether a region of interest identified in the feature map comprises a depiction of a brake light of a vehicle.
Non-transitory computer readable storage medium storing instructions to be executed by one or more processors, the instructions comprising:
- calculating an average pixel brightness of a plurality of pixels in an upper region of an image;
- determining whether the average pixel brightness exceeds a threshold value;
- extracting a feature map from the image in response to determining the average pixel brightness exceeds the threshold value;
- and
- determining whether a region of interest identified in the feature map comprises a depiction of a brake light of a vehicle.
