Abstract

At a high level, embodiments of the invention relate to augmenting video data with presence data derived from one or more proximity tags. More specifically, embodiments of the invention generate forensically authenticated recordings linking video imagery to the presence of specific objects in or near the recording. One embodiment of the invention includes video recording system comprising a camera, a wireless proximity tag reader, a storage memory and control circuitry operable to receive image data from the camera receive a proximity tag identifier identifying a proximity tag from the proximity tag reader, and store an encoded frame containing the image data and the proximity tag identity in the storage memory.

Claims

1. A non-transitory computer readable storage medium having a computer program stored thereon for associating image data for an event with a presence of a law enforcement officer with the event, wherein execution of the computer program by at least one processor performs the following steps:

receive an item of image data from an image data recording device mounted on one of the law enforcement officer and a law enforcement vehicle;

receive information indicative of a proximity tag identifier for a proximity tag associated with the law enforcement officer; and

generate an augmented frame comprising the item of image data and the information indicative of the proximity tag identifier to associate the item of image data with the information indicative of the proximity tag identifier to thereby associate the presence of the law enforcement officer with the event.

2. The computer readable storage medium of claim 1,

wherein the law enforcement officer is a first law enforcement officer, the item of image data is a first item of image data, the image data recording device is a first image data recording device, the proximity tag identifier is a first proximity tag identifier, and the proximity tag is a first proximity tag,

wherein execution of the computer program by the at least one processor performs the following steps:

receive a second item of image data from a second image data recording device, and

receive information indicative of a second proximity tag identifier for a second proximity tag associated with one of the first law enforcement officer and a second law enforcement officer,

wherein said generated augmented frame further comprises the second item of image data and the information indicative of the second proximity tag identifier to thereby associate one of the first law enforcement officer and the second law enforcement officer with the event.

3. The computer readable storage medium of claim 2, wherein the second image data recording device is mounted on another of the law enforcement officer and the law enforcement vehicle.

4. The computer readable storage medium of claim 1, wherein execution of the computer program by the at least one processor performs the step of receiving sensor data from at least one sensor associated with the event, wherein said generated augmented frame further comprises the sensor data to thereby associate the sensor data with the event.

5. The computer readable storage medium of claim 4, wherein the at least one sensor is selected from the group consisting of:

a microphone, a clock, a global positioning receiver, a breath analyzer, a fingerprint reader, an accelerometer, and a holster event.

6. The computer readable storage medium of claim 5, wherein the sensor data and the information indicative of the proximity tag identifier are stored as metadata for the event.

7. The computer readable storage medium of claim 1, wherein the proximity tag associated with the law enforcement officer is associated with at least one of a law enforcement vehicle, a law enforcement badge, a weapon carried by the law enforcement officer, and officer identification carried by the law enforcement officer.

8. The computer readable storage medium of claim 1, wherein the proximity tag associated with the law enforcement officer is associated with at least one of handcuffs, a breath analyzer, a radar or lidar gun, and an evidence bag.

9. The computer readable storage medium of claim 1, wherein the generation of the augmented video is in response to a triggering event.

10. The computer readable storage medium of claim 9, wherein the triggering event is selected from the group consisting of:

activation of the law enforcement vehicle'"'"'s siren or light bar, an acceleration or velocity reading associated with the law enforcement vehicle, a position reading of either the law enforcement officer or the law enforcement vehicle, a holster event, and a biometric stress indicator associated with the law enforcement officer.

11. The computer readable storage medium of claim 1, wherein execution of the computer program by the at least one processor performs the steps of creating a digital signature corresponding to the generated augmented frame.

17. The computer readable storage medium of claim 6, wherein the sensor data and the information indicative of the proximity tag identifier are stored as metadata for the event.

20. The computer readable storage medium of claim 1, wherein execution of the computer program by the at least one processor performs the steps of creating a digital signature corresponding to the generated augmented frame.

12. A non-transitory computer readable storage medium having a computer program stored thereon for associating data for an event with a presence of a law enforcement device or person at the event, wherein execution of the computer program by at least one processor performs the following steps:

receive a first item of image data from a first image data recording device associated with the event, wherein the first image data recording device is any one of a body-mounted video recording device for a first law enforcement officer, a body-mounted video recording device for a second law enforcement officer, and an in-vehicle video recording device for a law enforcement vehicle;

receive a second item of image data from a second image data recording device associated with the event, wherein the second image data recording device is any one of said body-mounted video recording device for the first law enforcement officer, said body-mounted video recording device for the second law enforcement officer, and said in-vehicle video recording device for the law enforcement vehicle,

wherein the first image data recording device is different than the second image data recording device;

receive information indicative of a proximity tag identifier for a proximity tag associated with the law enforcement device or person; and

generate an augmented frame comprising the first and second items of image data and the information indicative of the proximity tag identifier to associate the first and second items of image data with the information indicative of the proximity tag identifier to thereby place the law enforcement device or person at the event.

13. The computer readable storage medium of claim 12, wherein the proximity tag associated with the law enforcement device or person is associated with at least one of the law enforcement vehicle, a law enforcement badge, a weapon carried by either of the first and the second law enforcement officer, and officer identification carried by either of the first and the second law enforcement officer.

14. The computer readable storage medium of claim 12, wherein the proximity tag associated with the law enforcement device or person is associated with at least one of handcuffs, a breath analyzer, a radar or lidar gun, and an evidence bag.

15. The computer readable storage medium of claim 12, wherein execution of the computer program by the at least one processor performs the step of receiving sensor data from at least one sensor associated with the event, wherein said generated augmented frame further comprises the sensor data to thereby associate the sensor data with the event.

16. The computer readable storage medium of claim 15, wherein the at least one sensor is selected from the group consisting of:

a microphone, a clock, a global positioning receiver, a breath analyzer, a fingerprint reader, an accelerometer, and a holster event.

18. The computer readable storage medium of claim 12, wherein the generation of the augmented video is in response to a triggering event.

19. The computer readable storage medium of claim 18, wherein the triggering event is selected from the group consisting of:
