Abstract

A video tagging method, a video analytics method, and a Computer Assisted Dispatch (CAD) system use incident reports for video tagging and searching. A CAD system is integrated with field-based video surveillance systems to aid in searching video content and subsequent tagging of the video content. The systems and methods can include extracting keywords from a CAD incident report and creating a small, focused, and incident-specific dictionary on which to perform video searching in real-time. The small, focused, and incident-specific dictionary increases tagging accuracy and reduces tagging processing time in the context of video analytics. Further, a multi-pass approach in real-time continually updates and disseminates to video cameras of interest the small, focused, and incident-specific dictionary as the CAD incident report is updated and as the incident of interest plays out.

Claims

1. A video tagging method based on an incident report and an associated incident-specific dictionary, comprising:

capturing keywords from the incident report related to an incident of interest at a first time period;

creating an incident-specific dictionary for the incident of interest based on the captured keywords;

capturing updated keywords at a second time period as the incident of interest unfolds;

updating the incident-specific dictionary with the updated keywords;

providing the updated incident-specific dictionary to at least one video camera capturing video based on a plurality of factors or providing the updated incident-specific dictionary to a back-end server communicatively coupled to the at least one video camera; and

utilizing the keywords and updated keywords from the incident report by the at least one video camera to tag captured video.

3. The video tagging method of claim 1, further comprising:

providing the incident-specific dictionary subsequent to the updating to another video camera based on the plurality of factors or a back-end server communicatively coupled to the another video camera.

4. The video tagging method of claim 1, wherein the keywords are categorized as location-related keywords and incident-related keywords.

5. The video tagging method of claim 4, wherein the plurality of factors comprise any of direct responders of the incident of interest, nearby responders of the incident of interest, location based on the location-related keywords, and probable routes based on the location-related keywords.

6. The video tagging method of claim 1, wherein the keywords are captured by a Computer Assisted Dispatch (CAD) system, wherein the incident-specific dictionary is created for the incident of interest by the CAD system, and wherein the CAD system is configured to disseminate the incident-specific dictionary and associated updates to the at least one video camera based on the plurality of factors.

7. The video tagging method of claim 6, further comprising:

receiving the incident-specific dictionary at the at least one video camera or the back-end server communicatively coupled to the at least one video camera;

capturing video by the at least one video camera;

tagging the captured video with the keywords from the incident-specific dictionary; and

uploading the captured video with the tagged keywords.

8. The video tagging method of claim 7, further comprising:

searching a plurality of videos using the tagged keywords as search terms.

9. The video tagging method of claim 7, further comprising:

analyzing the captured video for detection based on the keywords; and

providing an alert upon detecting one of the keywords in a portion of the captured video.

10. The video tagging method of claim 1, wherein the at least one video camera comprises a mobile digital video recorder.

11. The video tagging method of claim 1, wherein the at least one video camera comprises a surveillance camera and one of the plurality of factors comprises proximity to the incident of interest.

2. (canceled)

16. The video analytics method of claim 2, wherein the first camera comprises a surveillance camera in proximity to the incident of interest based on the incident-specific dictionary and the second camera comprises a mobile video data recorder associated with a responder based on the updated incident-specific dictionary.

12. A video analytics method, comprising:

developing an incident-specific dictionary based on an incident report related to an incident of interest, wherein the incident-specific dictionary comprises a focused list of objects and people based on the incident report;

receiving the incident-specific dictionary at a first camera or the back-end server communicatively coupled to the first camera based on geographic proximity to the incident of interest;

capturing video by the first camera;

tagging the captured video by the first camera or the back-end server with keywords in the incident-specific dictionary; and

analyzing the captured video using the keywords in the incident-specific dictionary to perform video analytics based on the focused list;

receiving an updated incident-specific dictionary at a second camera or a back-end server communicatively coupled to the second camera based on the updated incident-specific dictionary;

capturing video by the second camera; and

tagging the captured video by the second camera with keywords in the updated incident-specific dictionary.

14. The video analytics method of claim 12, further comprising:

uploading the captured video by the first camera;

uploading the captured video by the second camera;

storing the captured video by the first camera tagged with the keywords in the incident-specific dictionary; and

storing the captured video by the second camera tagged with the keywords in the updated incident-specific dictionary.

15. The video analytics method of claim 14, further comprising:

searching video comprising the captured video by the first camera and the captured video by the second camera comprising search terms comprising the keywords in the incident-specific dictionary and the keywords in the updated incident-specific dictionary.

13. (canceled)

17. A Computer Assisted Dispatch (CAD) system, comprising:

a network interface communicatively coupled to a network;

a processor communicatively coupled to the network interface;

memory comprising instructions that, when executed, cause the processor to;

capture keywords from an incident report related to an incident of interest at a first time period;

create an incident-specific dictionary for the incident of interest based on the captured keywords;

provide, via the network interface, the incident-specific dictionary from the first time period to at least one video camera capturing video or to a back-end server communicatively coupled to the at least one video camera based on a plurality of factors;

capture updated keywords as the incident of interest unfolds at a second time period;

update the incident-specific dictionary with the updated keywords; and

provide the updated incident-specific dictionary to another video camera or to a back-end server communicatively coupled to the another video camera based on the plurality of factors.

18. The CAD system of claim 17, wherein the plurality of factors comprise any of direct responders of the incident of interest, nearby responders of the incident of interest, location based on the location-related keywords, and probable routes based on the location-related keywords.

19. The CAD system of claim 17, wherein the instructions that, when executed, further cause the processor to:

receive an alert from one of a plurality of video cameras or associated back-end server that a keyword from the incident-specific dictionary or the updated incident-specific dictionary has been detected in captured video, wherein the alert is generated based on video analytics using the incident-specific dictionary.

20. The CAD system of claim 1617, wherein the instructions that, when executed, further cause the processor to:

receive captured video from the at least one video camera or associated back-end server with the captured video tagged with keywords from the incident-specific dictionary; and

perform video analytics on the captured video using the incident-specific dictionary associated therewith.
