Automatic video surveillance system and method
First Claim
1. A method for automatic surveillance of a monitored area via an aerial vehicle, the method comprising:
- receiving region of interest (ROI) data indicative of spatial location of regions of interest in a scene;
receiving object of interest (OOI) data indicative of characteristics of one or more objects potentially situated within the scene;
calculating a repeated sequence of lines of sight (LOS) of a video imaging device, wherein the calculating of the sequence is carried out by weighting;
the OOI data;
properties of the video imaging device; and
properties of the aerial vehicle,automatically pointing the video imaging device at the scene based on the calculated repeated sequence of LOS;
applying automatic feature detection algorithms to the video images of the regions of interest, based on OOI data;
issuing an alert upon detection of the one or more objects in the scene that are associated with the OOI data,wherein the characteristics comprise at least one of;
visual features, tempo spatial behavior, and location within the scene.

Abstract
Apparatus and method for automatic surveillance of a monitored area having one or more regions of interest using a video imaging device are disclosed. The method includes receiving data defining said one or more regions of interest and one or more characteristics of an object of interest; pointing the line of sight of the imaging device at a region of interest selected from said one or more regions of interest; automatically scanning the selected region of interest to detect said one or more characteristics of the object of interest and upon detection issuing an alert; and when said one or more regions of interest includes more than one region of interest, repeating the steps of pointing the line of sight of the imaging device and automatically scanning in a predetermined order of viewing of the regions of interest, and upon detection of said one or more characteristics of the object of interest issuing an alert, for each of the regions of interests.

10. An apparatus for automatic surveillance of a monitored area, the apparatus comprising:
-
an aerial vehicle-mounted video imaging device connected to a pointing mechanism; a processor; and a user interface, wherein the user interface is configured to;
(i) receive region of interest (ROI) data indicative of spatial location of regions of interest in a scene; and
(ii) receive object of interest (OOI) data indicative of characteristics of one or more objects potentially situated within the scene;wherein the processor is configured to calculate a repeated sequence of lines of sight (LOS) of a video imaging device, wherein the calculating of the sequence is carried out by weighting;
the OOI data properties of the video imaging device; and
properties of the mobile platform;wherein said pointing mechanism is configured to automatically point the video imaging device at the scene based on the calculated sequence of LOS; wherein the a processor is further configured to;
(i) apply automatic feature detection algorithms to the video images of the one or more regions of interest, based on OOI data; and
(ii) issue an alert upon detection of the one or more objects in the scene that are associated with the OOI data;wherein the characteristics comprise at least one of;
visual features, tempo spatial behavior, and location within the scene. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21)
