[0074] refer to figure 2 , figure 2 It is the first embodiment of the human body tracking method of the present invention, and the human body tracking method includes the following steps:
[0075] Step S10, determining the moving distance between each first user in the first infrared image and each second user in the second infrared image, and constructing a distance matrix and a hit matrix according to each moving distance, the first infrared image and the first infrared image Two infrared images are adjacent frame images, and each element in the hit matrix corresponds to a moving distance in the distance matrix.
[0076] In this embodiment, the execution subject is a human body tracking device. For convenience of description, the device is used to refer to the human body tracking device below. The apparatus can be any terminal device with image processing capability.
[0077] The device acquires two infrared images of adjacent frames for tracking, and the two infrared i...

[0112] refer to Figure 5 , Figure 5 This is the fourth embodiment of the human body tracking method of the present invention. Based on the fourth embodiment, step S14 includes:
[0113] Step S141, acquiring a first distance between each first user and the center of the first infrared image.
[0114] In this embodiment, the infrared image will be distorted, and the farther it is from the center of the image, the more serious the distortion will be. Therefore, distortion needs to be taken into account. For this, the device obtains the distance between each first user and the center paper of the first infrared image, that is, determines the distance between the first user and the center of the image, which is defined as the first distance L0.
[0115] Step S142: Determine the first correction value corresponding to each first user according to the first coefficient, the first distance corresponding to each first user, and the maximum temperature, and determine the first corr...
