Embodiment 1
[0131] This embodiment provides a multi-target tracking method based on SSD detection generalized label multi-Bernoulli video, see figure 1 , the method includes:
[0132] Step 1. Initialization: In the initial frame k=0, initialize the target i and perform sampling N(l) is the number of particles, and the prior probability density of multiple targets is: where I is the label set of the initial frame, is the target weight. Set the existence probability P of the target s is 0.99, extracting the convolution feature of target i
[0133] Step 2. Generalized Label Multi-Bernoulli Filter Prediction:
[0134] 2.1 Prediction of new targets: use the SSD detector to detect the k-th image, and obtain the multi-target detection results and target number Calculate the distance matrix D between the surviving target and the detection result through the center point distance k =[d i,j ],which is:
[0135]
[0136] Among them, d ij The matrix represents the center distance...
