Abstract

The present application is directed to systems and methods for capturing video from a sensor triggered camera. External automobile cameras run continuously and content is buffered. Buffer storage is triggered by one or more other automobile sensors to store content beginning at some period of time (e.g. 30 seconds) prior to the triggering of the sensor.

Claims

1. A method for capturing video from a sensor triggered camera, comprising:

receiving from a camera a video stream into buffer storage, the video stream associated with a period of time;

receiving from a sensor a signal indicating a triggering event during the period of time;

capturing a portion of the video stream in the buffer storage beginning prior to the triggering event and ending after the triggering event, the captured portion of the video stream being a subset of the video stream; and

saving the captured portion of the video stream in memory.

2. The method of claim 1, further comprising associating a time stamp, a GPS location, and non-video data with the saved portion of the video stream.

3. The method of claim 2, wherein the time stamp comprises one or more of a time of the triggering event, a time associated with the beginning of the saved portion of the video stream, and a time associated with the end of the saved portion of the video stream.

4. The method of claim 2, further comprising transmitting the time stamp, the GPS location, the non-video data, and the saved portion of the video stream to a networked intelligent agent.

5. The method of claim 2, wherein the non-video data comprises one or more of an identifier of the sensor that was triggered, an identifier of a vehicle on which the sensor is located, an identifier of a driver of the vehicle, a service history of the vehicle, and a status of other sensors that sense conditions of the vehicle or subsystems of the vehicle.

6. The method of claim 1, wherein receiving from the sensor the signal indicating a triggering event comprises receiving from the sensor a signal indicating a collision by a moving vehicle.

7. The method of claim 6, further comprises receiving the signal from an accelerometer sensor.

8. A method for capturing video from a sensor triggered vehicle camera, the method comprising:

receiving from a camera on a vehicle a continuous video stream into buffer storage;

receiving from a sensor on the vehicle a signal to transfer the continuous video stream from the buffer storage to a memory;

receiving from a system controller on the vehicle a first predefined time, the first predefined time indicating a time prior to the receiving of the signal in which to initiate a transfer of the continuous video stream from the buffer storage to the memory;

receiving from the system controller on the vehicle a second predefined time, the second predefined time indicating a time after the receiving of the signal to transfer in which to stop the transfer of the continuous video stream from the buffer storage to the memory; and

saving the continuous video stream in the memory.

9. The method of claim 8, further comprising associating a time stamp, a GPS location, and an identifier of the vehicle with the saved portion of the video stream.

10. The method of claim 9, wherein the time stamp comprises one or more of a time of the triggering event, a time associated with the beginning of the saved portion of the video stream, and a time associated with the end of the saved portion of the video stream.

11. The method of claim 9, further comprising transmitting the time stamp, the GPS location, the identifier of the vehicle, and the saved portion of the video stream to a networked intelligent agent.

12. The method of claim 8, wherein receiving from the sensor on the vehicle the signal to transfer the continuous video stream comprises receiving from the sensor a signal indicating a collision of the vehicle.

13. The method of claim 12, further comprises receiving the signal from an accelerometer sensor.

14. A system for capturing video from a sensor triggered vehicle camera, comprising:

a camera on a vehicle producing a continuous video stream;

a buffer storage communicatively coupled to the camera on the vehicle storing the continuous video stream for a period of time;

a sensor on the vehicle, the sensor communicatively coupled to the camera, the buffer storage and a memory on the vehicle;

a system controller on the vehicle, the system controller communicatively coupled to the camera, the sensor, the buffer storage, and the memory; and

an intelligent agent communicatively coupled over a network to the system controller on the vehicle, the intelligent agent configured to receive over the network from the system controller on the vehicle a portion of the saved continuous video stream, an associated time stamp, an associated GPS location, and an associated identifier of the vehicle.

15. The system of claim 14, wherein the sensor is capable of sensing a triggering event during the period of time of the continuous video stream.

16. The system of claim 15, wherein the system controller is operative to capture a portion of the video stream in the buffer storage beginning prior to the triggering event and ending after the triggering event, and saving the portion of the video stream in the memory.

17. The system of claim 16, wherein the time stamp comprises one or more of a time of the triggering event, a time associated with the beginning of the saved portion of the video stream, and a time associated with the end of the saved portion of the video stream.

18. The system of claim 14, wherein the sensor is operative to sense a collision of the vehicle.

19. The system of claim 14, wherein the sensor is operative to sense when a speed of the vehicle exceeds a predetermined speed limit.

20. The system of claim 14, wherein the sensor comprises one or more of an ultrasonic or microwave motion detector, a vibration sensor, a sound sensor, a differential pressure sensor, a radar sensor, a sonar sensor, a lidar sensor, a light sensor, a braking sensor, an accelerometer sensor, an impact sensor, a GPS sensor, and a video sensor.
