Abstract

An in-vehicle video system comprising a forward-looking video camera system that includes two independent image sensors and associated digital signal processors for processing imagery received from the respective independent image sensors. The in-vehicle-video system may also comprise a microphone and a transmitter; and a computing system for interfacing with the forward-looking video camera system configured to control the capture, storage and processing of video, still images and audio received from the transmitter and the forward-looking video camera system. The computing system is operable to control image capture including enabling the forward-looking video camera system in a plurality of modes, and to command the forward-looking video camera system to transition to a first mode including commanding a first independent image sensor to capture high-resolution video imagery while a second independent image sensor of the two independent image sensors is capturing still images.

Claims

1. An in-vehicle video system comprising:

a forward-looking video camera system including two independent image sensors and associated digital signal processors for processing imagery received from the respective independent image sensors;

a microphone and a transmitter;

a computing system for interfacing with the forward-looking video camera system configured to control the capture, storage and processing of video, still images and audio received from the transmitter and the forward-looking video camera system; and

the computing system operable to control image capture including enabling the forward-looking video camera system in a plurality of modes, the computing system operable to command the forward-looking video camera system to transition to a first mode including commanding a first independent image sensor to capture high-resolution video imagery while a second independent image sensor of the two independent image sensors is capturing still images, and to transition to a second mode wherein the first independent image sensor captures and compresses video while the second independent image sensor analyzes objects in a field of view of the second independent image sensor and takes preprogrammed actions when objects are recognized in the field of view and/or other vehicle sensors provide input that match a predefined set of target situations.

2. The in-vehicle video system of claim 1 wherein the vehicle sensors include sensors related to a speed or movement of an associated vehicle.

3. The in-vehicle video system of claim 1 further comprising an interface coupled between the forward-looking video camera system and the computing system for passing commands and video and captured imagery between the respective components.

4. The in-vehicle video system of claim 3 wherein the computing system receives data in the form of compressed video and still imagery from the interface and is operable to perform further processing, user presentation and storage of the received or further processed data.

5. The in-vehicle video system of claim 1 wherein the microphone further includes a wireless microphone configured for easy deployment on or in proximity to an operator of the vehicle for capturing audio data associated with events along with video and still imagery captured by the forward-looking video camera system.

6. The in-vehicle video system of claim 1 further comprising a sensor box that receives inputs from one or more vehicle sensors and provides sensor input to the computing system to enable the execution of the preprogrammed actions.

7. The in-vehicle video system of claim 6 wherein the vehicle sensors are selected from the group comprising a GPS, accelerometer, temperature, or analog or digital sensors coupled to different components of the vehicle so as to enable the sensor box to sense and react to a change of state of the vehicle and initiate one or more preprogrammed actions for execution by the forward-looking video camera system.

8. The in-vehicle video system of claim 1 wherein the computing system further includes a circular buffer configured to store a predetermined amount of received data.

9. The in-vehicle video system of claim 8 wherein the predetermined amount is approximately 10-100 hours of video data.

10. The in-vehicle video system of claim 1 further comprising:

one or more secondary cameras configured to capture video and still images;

wherein the computing system is further operable to interface with the one or more secondary cameras and process and store video and still images received from the one or more secondary cameras.

11. A method for capturing event data associated with a vehicle comprising:

providing a forward-looking video camera system including two independent image sensors and associated digital signal processors for processing imagery received from the respective independent image sensors;

providing a microphone and transmitter; and

detecting, using at least one of the two independent image sensors, a first operating condition and, based on the detecting, controlling the forward-looking video camera system to operate in a first mode including;

using a first independent image sensor and associated digital signal processor to capture and compress video; and

using a second independent image sensor of the two independent image sensors and associated digital signal processor to analyze objects in a field of view of the second independent image sensor including;

detecting an object in the field of view, recognizing the object and, based on the detecting and recognizing, capturing a still image of the recognized object; and

detecting a change of state of the vehicle or an event associated with the vehicle and, based on the detecting of the change in state, capturing imagery or video based on a preprogrammed action associated with a given detected change of state or event.

12. The method of claim 11 wherein the object is a license plate and the method further includes comparing a license number in a list of wanted license numbers and providing an alert to an operator when a match is detected.

13. The method of claim 11 wherein detecting a change of state includes detecting that vehicle emergency lights or sirens are activated and detecting a rate of speed above a predetermined amount for the vehicle, and wherein the preprogrammed action includes searching for and capturing still images of faces or a target vehicle in front of the forward-looking video camera system.

14. The method of claim 13 wherein the preprogrammed action includes also capturing license plate imagery associated with the target vehicle.

15. The method of claim 11 wherein the detected state is emergency lights on and vehicle stopped, and wherein the preprogrammed action is capturing a series of images so as to be able to identify one or more of make, model, color, license plate, markings, or occupants in a target vehicle.

16. The method of claim 11 wherein the event is a fight or struggle between an operator of the vehicle and an occupant of a target vehicle, and wherein the preprogrammed action is capturing high-resolution video or imagery, and wherein the method further includes activating a warning signal upon detecting the event.

17. The method of claim 11 wherein the change of state is vehicle stopped with emergency lights on and the preprogrammed action includes evaluating a scene presented to the second independent image sensor to detect one or more predetermined scenarios.

18. The method of claim 17 wherein the scenarios are selected from the group comprising identifying a suspect, detecting a discharge of a weapon, detecting a fight or struggle, or detecting administration of a road side test by the operator of the vehicle.

19. The method of claim 17 further comprising disseminating information related to the scenarios to other entities in law enforcement depending on or more criteria associated with the detected scenario.

20. The method of claim 11 further comprising receiving a signal from an operator of the vehicle to capture a high-resolution image with the second independent image sensor or to start or stop video recording with the first independent image sensor.
