Abstract
In a method for smart roadway alerts, a roadway alert device, coupled to a vehicle: receives a video stream including a video of a location of a roadway from a video camera; decodes the video stream to extract a set of video frames; analyze the set of video frames to detect one or more risk events; generates a risk alert for each of the one or more risk events; and sends the risk alert to the vehicle.
Claims20
A method for smart roadway alerts, comprising:
- detecting a presence of a video camera of a smart mirror by a roadway alert device at a first time, the roadway alert device coupled to a vehicle and comprising a communications engine, a video codec and an analytics engine, the video camera external to the vehicle;
- receiving, by the communications engine of the roadway alert device, a video stream comprising a video of a location of a roadway from the video camera, wherein the smart mirror is located such that at the first time the vehicle is not visible in a field of view of the video camera and at a second time the vehicle is visible in the field of view of the video camera;
- decoding, by the video codec of the roadway alert device, the video stream to extract a set of video frames;
- analyzing, by the analytics engine of the roadway alert device, the set of video frames to detect one or more risk events;
- generating, by the analytics engine of the roadway alert device, a risk alert for each of the one or more risk events;
- and
- sending, by the roadway alert device, the risk alert to the vehicle.
A computer program product for smart roadway alerts for a roadway alert device, the roadway alert device coupled to a vehicle and comprising one or more processors, a communications engine, a video codec and an analytics engine, the computer program product comprising one or more computer readable storage media, and program instructions collectively stored on the one or more computer readable storage media, the program instructions executable by the one or more processors to cause the one or more processors to:
- detect a presence of a video camera of a smart mirror by the roadway alert device at a first time, the video camera external to the vehicle;
- receive, by the communications engine of the roadway alert device, a video stream comprising a video of a location of a roadway from the video camera, wherein the smart mirror is located such that at the first time the vehicle is not visible in a field of view of the video camera and at a second time the vehicle is visible in the field of view of the video camera;
- decode, by the video codec of the roadway alert device, the video stream to extract a set of video frames;
- analyze, by the analytics engine of the roadway alert device, the set of video frames to detect one or more risk events;
- generate a risk alert for each of the one or more risk events;
- and send the risk alert to a vehicle.
A system comprising:
- a roadway alert device coupled to a vehicle, the roadway alert device comprising a communications engine, a video codec and an analytics engine, the roadway alert device for:
- detecting a presence of a video camera at a first time, the video camera external to the vehicle and incorporated in a smart mirror, wherein the smart mirror is located such that at the first time the vehicle is not visible in a field of view of the video camera and at a second time the vehicle is visible in the field of view of the video camera;
- receiving, by the communications engine, a video stream of a location of a roadway from the video camera;
- decoding, by the video codec, the video stream to extract a set of video frames;
- analyzing, by the analytics engine, the set of video frames to detect one or more risk events;
- generating a risk alert for each of the one or more risk events;
- and
- sending the risk alert to the vehicle.
