Target tracking method based on adaptive context awareness

The invention provides a target tracking method based on adaptive context awareness. The method comprises the following steps: initializing a Kalman filter, a position correlation filter and a scale correlation filter; respectively estimating the target position in the (t + 1) th frame by using the Kalman filter and the position correlation filter in the tth frame, and determining the target position in the (t + 1) th frame according to the tracking confidence of the position correlation filter; estimating a target scale in the (t + 1) th frame by using a scale correlation filter in the tth frame; updating the Kalman filter; and when the tracking confidence coefficient is greater than a certain threshold value, updating a position correlation filter by using the position and the scale of the optimal target area and the interference background area with high confidence coefficient, and updating a scale correlation filter. According to the invention, the correlation filter is updated by using the interference b
