Abstract

Embodiments for the detection of mobile device use in a motor vehicle are disclosed. As one example, a system and method are disclosed in which an image of a scene is captured via a camera. The presence of a graphical display of a mobile device is detected within the scene by processing the image to identify a signature pixel characteristic indicative of a graphical display in a portion of the scene corresponding to a driver'"'"'s position within a vehicle frame of reference. An indication of a positive detection of the graphical display is output by the system.

Claims

1. A method for detecting presence of a graphical display of a mobile device within a motor vehicle, comprising:

capturing an image of a vehicle being operated on a public roadway;

determining a location of a driver'"'"'s seat region of the vehicle within the image;

detecting the presence of an illuminated graphical display in the driver'"'"'s seat region of the vehicle in the image, the presence of the graphical display being detected by;

processing the image to identify a signature pixel characteristic indicative of a graphical display in the driver'"'"'s seat region of the vehicle in the image; and

outputting an indication of a positive detection of the graphical display.

2. The method of claim 1, wherein the signature pixel characteristic includes one or more of a hue, value, chroma, brightness, and/or luminosity.

3. The method of claim 1, wherein outputting the indication includes presenting the image via a graphical display for inspection by personnel.

4. The method of claim 1, wherein outputting the indication includes transmitting image data including the image to a remote computing device via a communication network.

5. The method of claim 1, wherein outputting the indication includes mailing the image to a mailing address associated with the vehicle along with a government issued citation.

6. The method of claim 1, wherein the image is a first image, the method further comprising:

capturing a second image from a different perspective than the first image, the different perspective enabling a license plate of the vehicle to be visible in the second image; and

presenting the second image or outputting an identifier of the license plate captured in the second image responsive to positive detection of the graphical display.

7. The method of claim 1, further comprising:

detecting the driver'"'"'s position within the vehicle frame of reference by;

processing the image to identify a window of the vehicle; and

outputting the indication of the positive detection only if the graphical display is present within an interior region of the window corresponding to the driver'"'"'s seat region of the vehicle.

8. The method of claim 1, wherein processing the image includes applying edge detection algorithms to the image to identify characteristic shape of the graphical display.

9. The method of claim 1, wherein processing the image includes applying a filter to the image to identify the signature pixel characteristic including one or more of a hue, value, chroma, brightness, and/or luminosity.

10. The method of claim 1, wherein capturing the image is performed responsive to satisfaction of a trigger condition, the trigger condition indicating the presence of the vehicle.

11. The method of claim 1, further comprising:

processing the image to identify a finger of the driver obstructing a portion of the graphical display.

12. A system for detection of a driver'"'"'s mobile device use while operating a motor vehicle, comprising:

a camera positioned to capture an image of a driver'"'"'s side of a motor vehicle while the vehicle is being operated on a public roadway;

a computing device being configured to receive the image from the camera, and process the image to identify a graphical display of a mobile device being operated by the driver of the vehicle.

13. The system of claim 12, wherein the computing device is configured to process the image by detecting a signature pixel characteristic selected from the group consisting of hue, value, chroma, brightness, and luminosity.

14. The system of claim 12, wherein the computing device is further configured to process the image by identifying a target region of the image at which the driver'"'"'s side window is located.

15. The system of claim 14, wherein the computing device is configured to identify the target region by extracting features of the vehicle including detected wheels and/or outline of the vehicle, and locating the estimated position of the driver'"'"'s side window based on the extracted features.

16. The system of claim 12, wherein the computing device is further configured to process the image by identifying the signature pixel characteristic in each of a plurality of contiguous pixels covering at least a threshold area within the image.

17. The system of claim 12, further comprising:

a sensor configured to sense a predetermined position of the motor vehicle;

a controller being configured to receive a signal from the sensor indicating the motor vehicle is in the predetermined position, and in response to send a signal to the camera to cause the camera to capture the image.

18. The system of claim 17, wherein the controller is configured to associate meta data with the image including location and time.

19. A system for detecting presence of a graphical display of a mobile device within a motor vehicle, comprising:

a first camera to capture a first image of a scene from a first perspective;

a second camera to capture a second image of the scene from a second perspective;

a computing system configured to;

receive the first image and the second image from the first camera and the second camera;

detect presence of a graphical display within the scene by processing the first image to identify a signature pixel characteristic indicative of the graphical display in a portion of the scene corresponding to a driver'"'"'s position within a vehicle frame of reference, the signature pixel characteristic including one or more of a hue, value, chroma, brightness, and/or luminosity;

transmit the second image to a remote computing device via a communication network, or present the second image responsive to a positive detection of the graphical display responsive to a positive detection of the graphical display.

20. The system of claim 19, wherein the computing device is further configured to process the first image by identifying a target region of the image at which the driver'"'"'s side window is located.
