Embodiment Construction
[0036] Now in conjunction with embodiment, accompanying drawing, the present invention will be further described:
[0037] The experimental data source of the embodiment includes a 200-frame image sequence (640*512) and corresponding detected target position data.
[0038] The specific implementation steps of the present invention are as follows:
[0039] 1) Data association
[0040] The data association adopts the predicted track, which has been filtered for k times. Calculate the residual error of the filter according to the Kalman filter principle Residual covariance matrix S and residual norm d 2 :
[0041]
[0042] S=HP(k / k)H T +R(k) (2)
[0043]
[0044] In the formula, H is the measurement matrix, is the filter output, P(k / k) is the error covariance matrix, R(k) is the measurement noise covariance matrix, c is the correlation threshold, and the adaptive threshold is adopted.
[0045] 2) Track evaluation
[0046] First, take the track Track(k-1) in the 5...
