3D monitoring of sensors physical location in a reduced bandwidth platform
Systems and methods for controlling the recording, storing and transmitting of video content captured by security cameras in order to drastically reduce the overall bandwidth required to remotely monitor a physical space. More specifically, embodiments of the present invention relate to a method of triggering or activating a video camera to record and/or transmit images of a physical environment over a network only when measurements taken by a separate structural sensor camera or depth-sensing device indicate that sufficient physical changes have occurred in the environment to warrant video recording. Embodiments of the invention pair video cameras with structural depth sensors, along with enhanced on-board processing techniques, to increase the recording and transmitting efficiency of video cameras by recording and/or transmitting video streams only when something in the physical environment monitored by a depth sensor is determined to have changed or moved, or is determined by processing algorithms to be important or significant. A security function and a library of image processing analytics are also disclosed for processing static and dynamic image states within the measured physical space.
1. A video surveillance system comprising:
a video camera configured to monitor a physical space;
a three-dimensional (3D) depth sensor configured to measure the physical space;
a control system in communication with the video camera and the 3D depth sensor, the control systet comprising a software application executable on a computing system, the control system configured to receive real-time video images of the physical space from the video camera, the control system further configured to record the real-time video images, the control system further configured to capture a 3D baseline measurement of the physical space from the 3D depth sensor and to capture 3D subsequent measurements of the physical space from the 3D depth sensor; and
an analytic module operable with the control system, the analytic iodule configured to compare each 3D subsequent measurement to the 3D baseline measurement, each said 3D subsequent measurement comprising a data model indicative of new 3D objects in the physical space that were not present in the 3D baseline measurement, the analytic module further configured to trigger the control system to record the real-time video images whenever a statistical confidence measure associated with the data model exceeds a predetermined threshold value.
