Automatic target tracker for main battle tank

The moving object tracking in video pictures has attracted a great deal of interest in computer vision. For object recognition, navigation systems and surveillance systems, object tracking is an indispensable first-step. Automatic target tracker (ATT) is one of improvement in main battle tank. The goal of an automatic target tracking system is to maintain a stable image sensor-to-target line of sight (LOS) in the presence of relative target motion and base motion disturbance to the sensor platform due to harsh terrain conditions in the war field. The proposed system works on the real time video which is acquired through Tank Sight system. ATT performs Normalized Area Correlation algorithm on real time video and computes the deviation of target with respect to bore-sight (tracking window) and sends error signal to the Main Sight System. This error signal replaces the Gunner's command signal. We can detect all objects in images no matter whether they are moving or not. The proposed technique ensures robust tracking of the ground target in a complex background in the war field.
