[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...

Abstract
The invention provides a human body tracking method and related equipment, and the method comprises the steps: determining a movement distance between each first user in a first infrared image and each second user in a second infrared image, and constructing a distance matrix and a hit matrix according to each movement distance; determining a minimum distance in the distance matrix, and determining the first user and the second user corresponding to the minimum distance as the same user; setting the value of each first element in the hit matrix as a preset value; and when the values of all the elements in the hit matrix are not the preset values, returning to execute the step of determining the minimum distance in the distance matrix. According to the human body tracking method and device, human body tracking can be achieved through the moving distance between the users in the two adjacent frames of infrared images, interference of the tracked human body is eliminated by changing the values of the elements in the hit matrix, human body tracking precision is improved, and high-precision human body tracking is achieved at low tracking cost.
Description
technical field [0001] The invention relates to the technical field of thermal imaging, and in particular, to a human body tracking method and related equipment. Background technique [0002] Human tracking technology is a technology that uses monitoring equipment to track tasks, which can be applied to fields such as security prevention and control. [0003] At present, the human body tracking technology obtains video through monitoring equipment, marks the position frame of the human body in the previous frame of the video, and then uses the position frame to track the human body in the next frame of image. This method needs to mark the position frame through the trained model, and the training of the model requires a high cost, and the algorithm used for the mark of the position frame is relatively complicated, which makes the cost of human body tracking relatively high. SUMMARY OF THE INVENTION [0004] The present invention provides a human body tracking method and r...
