System and method for activity monitoring using video data
Embodiments of a method and system described herein enable capture of video data streams from multiple, different devices and the processing of the video data streams. The video data streams are merged such that various data protocols can all be processed with the same worker processors on different types of operating systems, which are typically distributed. An embodiment uses a mobile device (such as a mobile phone) as a device and deploys a video sensor application on the mobile device for encoding consecutive video files, time stamping the consecutive video files, and pushing the consecutive video files to a file server to produce a stable stream of video data. Thus avoiding the inefficiencies associated with having video processing in the data flow loop.
1. A computer implemented video data processing method, comprising:
a plurality of special purpose video analysis processors receiving a plurality of video data streams from multiple sources of different types in different locations that generate different types of video data streams;
the plurality of special purpose video analysis processors executing a plurality of video analysis worker processes that operate on the different types of video data streams to generate processed video data that includes real time information related to scenes; and
executing a video sensor application on a mobile device which is one of the multiple sources, wherein the video sensor application performs various functions using the mobile device, the functions comprising,
encoding consecutive video files;
time stamping the consecutive video files; and
pushing the consecutive video files to a file server to produce a stable stream of video data.
2. The method of claim 1 , further comprising the plurality of video analysis worker processes operate on the video data streams to unify geolocation and time reference information from the plurality of video data streams such that processed video data having similar geolocation and time reference information generated from the multiple sources can be compared.
3. The method of claim 1 , further comprising the plurality of video analysis worker processes operate on the video data streams to:
gather and store processed data from the plurality of the different types of video streams;
architecturally removing any dependency of the special purpose video analysis processors on the different types of video data streams;
merging the video data from the multiple sources; and
packaging and serving processed data as an output.
4. The method of claim 1 , wherein the plurality of video analysis worker processes are accessible via a plurality of application programming interfaces such that the video analysis worker processes instantiated on and executable on a plurality of operating systems, wherein the operating systems comprise Linux, Mac OS, and Windows.
5. The method of claim 4 , wherein the plurality of video analysis worker processes report level their level of central processing unit (CPU) activity, availability, and data storage capacity.
