Embodiment

[0055] The basic steps of heatmap partitioning are as follows:

[0056]Zoning Standard

[0057] According to the needs of medical research and clinical diagnosis, from the medical point of view, the infrared heat map can be divided into multiple divisions, such as anatomical division, nerve innervation division, pain division and so on. These partitions can be divided in the form of standard people. Each group of partitions includes geometric parameters such as contour lines, partition lines and positioning reference points (see Figure 1-2 ).

[0058] figure 1 is the innervation diagram, figure 2 It is a map of facial divisions for upper respiratory diseases. These graphics are composed of contour lines, geometric line segments (bar line segments) for area division, and positioning reference points (black dots). These parameters can be scaled proportionally. For the sake of description here, let the standard partition map be: PPG.

Abstract

The invention discloses a head and face thermal field distribution algorithm-based infrared thermograph partitioning method and device. The infrared thermograph partitioning method comprises the following steps: (1) partition standard establishment: according to the requirements of medical research and clinical diagnosis, multi-division partitioning is conducted on an infrared thermograph I from the perspective of medicine, and each partition includes a contour line, a partition line and geometric parameters of a location reference point; (2) graph outline extraction: a human body outline is extracted from the infrared thermograph I, and vectorizing is performed; (3) location mark extraction: feature points in the graph and the outline are extracted; (4) graph registration: a standard partition map is called according to the position code of the graph, and registration is performed on the infrared thermograph I and the standard partition map; and (5) partitioning realization: partitioning of the human body thermograph is realized. The head and face thermal field distribution algorithm-based infrared thermography device can obtain accurate and effective human body infrared thermograph to detect an infected person, and help epidemic outbreak restrained.

Description

technical field [0001] The invention relates to an infrared heat map partitioning method and device based on a heat field distribution algorithm of the head and face. Background technique [0002] Viral infectious diseases transmitted through the respiratory system, on the one hand, because the infected person has no obvious symptoms during the incubation period, and on the other hand, with the mobility of people, the viral infectious diseases that spread can easily cross regions and borders, and in a short period of time In just two or three months, there will be a global outbreak trend. In the face of such an epidemic, early detection and isolation of infected persons is a necessary means to contain the outbreak. [0003] Because people infected with this type of virus are usually accompanied by elevated body temperature, it is necessary to use infrared technology to take remote sensing body temperature detection for mobile populations. Therefore, obtaining accurate and ...
