More video from Sensor Cast’s MobilHD system (see yesterday’s post for more details).
MobilHD demonstrates the SPOT automatic object tracking system using a pan-tilt-zoom camera. Unlike simple motion detection, MobilHD employs sophisticated video signal processing to find, track, and predict moving objects within the field of view. First objects are detected as shown by tiny yellow crosses. Then, their size is estimated as shown by the white rectangle that encompasses the object. As the tracker develops increased confidence, the rectangle’s color changes to red. After the object is tracked for 10 seconds, the tracker breaks off and acquires a new object. Whenever the camera zooms or pans, the tracker is essentially blind and must therefore predict the objects trajectory and re-acquire.
