Tracking objects in multiple camera vision systems for Stage tracking and Intelligent surveillance applications.
World first Real Time, Real world, XYZ & Geo location tracking in Multi Camera enviroment.
Placing camera near the stage gives us detailed image for close and accurate tracking. Being close to the stage, camera will have with limited field of view. To expand the camera field of view, and to keep high accuracy tracking, we will just put another camera.
Cameras can be placed in any position regarding the stage. Camera output image is mapped over a real-world coordinates for a true 3D tracking.
This innovative design have reduce the load on a stage riggers. Video camera can be placed on a stage backdrop, or on a side of the stage at the height that do not legally require licenced riggers.
System will automatically set a performer height correction and adjust each moving light beam accordingly.
Light beam shape, Zoom , Iris and Focus and Light intensity are automatically adjusted by the system accordingly to performer relative position to a moving light a position.
Multi Track system uses one computer and allow up to 4 operators to track 4 stage performers in real time, thus requiring minimum amount of hardware. System is using PC mouse to track the stage performer meaning that no specialised hardware is required.
System design is following a simple nature law, if one eye is not enough for the job, another eye will be added. If two eyes are not enough for the job, eight eyes will be added. If a brain cannot process eight images in real time, images are going to be used as a simple motion detectors.
Multi camera technology is a game changer in visual tracking systems. For a first time, video camera is used as high sensitive motion detector that is aware of the distance and object dimension (width and height) in it's field of view. Distance and direction from camera to a detected object, as well as object dimensions in video stream are now calculated in meters. This unique feature has enabled us to GEO coordinates of every detected object in camera field of view. This simple but effective tool have finally laid groundwork for integration platform of video surveillance systems with location-based applications.
Every pixel in camera output image is mapping one GEO coordinate. Every pixel in image is calculated as GEO coordinate. Every moving object dimensions and position are displayed on a GEO map.
Blue Face Spider multicamera vision system have inspire us in creating multi camera system. It’s highly specialised vision system that is a stunning demonstration of evolutionary design of multicamera vision system.
Multicamera system have divided tasks of image processing to different dedicated systems. GEO Mapping system will send GEO location of each detected object. Tracking system will calculate amount of pan and tilt to direct one or more cameras in required position. Control system will calculate amount of zoom required by each camera. Low resolution cameras are used as a high sensitive motion detector in a large area video surveillance applications, so that all moving objects that are detected in all of the cameras field of view are displayed on one GSP map.
Using GEO coordinates have enable the security officer to manually direct cameras. Security officer will place a mouse pointer over a geo map and all of the cameras that can reach that position will be directed in that position, automatically adjusting the zoom for each PTZ camera. Event triggering the alarm will automatically direct PTZ camera in required position and activate recording reducing delay time to minimum.
In large outdoor video surveillance of critical infrastructure or public safety systems, in stadium applications, PTZ camera are used for public safety during the event and for parameter protection during none working hours.
