Embodiment 1
[0029] See figure 1 , figure 1 The embodiment of the present invention provides a block diagram of a fast infrared small target extraction system module, including:
[0030] An image acquisition module, configured to acquire an image of a target to be detected;
[0031] At least one image scaling module, connected to the image acquisition module, for reducing the image of the target to be detected;
[0032] The target extraction module is connected to the image scaling module, and is used to extract target points from the reduced target image to be detected, and extract the feature value of the target points;
[0033] A target judgment module, connected to the target extraction module, for judging whether the target point is a target to be extracted according to the feature value, and if so, recording the position of the target to be extracted;
[0034] A data cache module, connected to the image acquisition module, for storing the image of the target to be detected.

Embodiment 2
[0051] This embodiment uses a specific example to illustrate how the system performs hardware processing corresponding to the extraction algorithm. First, the algorithm applied to the system of the present invention is described. Wherein the method comprises the following steps:
[0052] S1. Select the target image to be detected, determine the template according to the size of the target unit in the target image to be detected, and map the template to the detection window of the target image to be detected, wherein the template is a window with a size of M*M pixels , where M≤20;
[0053] S2. Divide the template into a first annular area, a second annular area, and a third annular area in sequence from the inside to the outside, and make the second annular area include at least 8 sub-pixels;
[0054] S3. Divide the second annular area into 8 consecutive first sub-areas, and correspondingly, divide the third annular area into 8 continuous second sub-areas;
[0055] S4. Calcul...
