Embodiment Construction
[0139] combine figure 1 , a fast multi-sensor potential probability hypothesis density filtering method of the present invention, comprising the following steps:
[0140] S1, there are a total of Y sensors in the scene, and the sensor numbers γ∈{1, 2, ..., Υ}; set the initial moment k=0, initialize the potential distribution (target number distribution) ρ 0 (n) and probability hypothesis density D 0 (x);
[0141] S2, the probability hypothesis density D of the previous moment (k-1 moment) k-1 (x) and potential distribution ρ k-1 (n), predict the current moment (k moment), and obtain the predicted probability hypothesis density D k|k-1 (x) and predicted potential distribution ρ k|k-1 (n);
[0142] S3, obtain the measurement set of sensor γ at the current moment in is the measurement state, is the number of measurements, through the measurement set of each sensor, calculate the weight matrix and cost matrix of each sensor;
[0143] S4, using the cost matrix obtained...
