Embodiment 1
[0069] like figure 1 As shown, an example is used to illustrate the real-time tracking method of infrared image target by multi-feature fusion of the present invention. The number of pixels of the infrared image is 320×240, and the frame rate is 25HZ. The imaging of the infrared thermal imager is transmitted to the special image processing board of the DSP+FPGA architecture through the optical fiber, and the infrared image target tracking of multi-feature fusion is realized in the DSP processor to meet the needs of real-time processing. The specific implementation steps are as follows:
[0070] (1) Initialize the target tracking point position y 0 , the initial tracking point is manually specified.
[0071] Manually specify the initial target tracking point position (i, j), i = 80, j = 100 (as shown in Figure 2), and set the Epanechnikov (Epanechnikov) kernel function bandwidth h = 10.
[0072] (2) Initialize the target model and establish the target grayscale model q accor...
