In order to improve the effect of infrared treatment, an embodiment of the present invention provides a lower limb infrared treatment apparatus, which is shown in fig. 1 and includes: the lower limb movement training device 10, the thermal imaging system 20, the control module 30 and the plurality of infrared physiotherapy lamps 40.
Wherein, the plurality of infrared physiotherapy lamps 40 are respectively installed at the parts corresponding to the lower limb joints in the lower limb movement training device 10; the lower limb movement training device 10, the thermal imager 20 and the plurality of infrared physiotherapy lamps 40 are electrically connected with the control module 30; the connection lines in fig. 1 indicate this electrical connection.
And a thermal imaging camera 20 for taking a whole body thermal imaging image of the treatment subject.
The control module 30 is used for extracting body characteristics of the treatment object from the whole-body thermal imaging image, wherein the body characteristics comprise body shape characteristics and lower limb temperature characteristics; determining an infrared treatment scheme of the treatment object according to the body characteristics; triggering a plurality of infrared physiotherapy lamps 40 to treat the treated object according to the infrared treatment scheme; wherein the infrared treatment protocol is used to specify a power exposure profile of the plurality of infrared physiotherapy lamps 40 over time.
The manner of extracting the body shape feature from the whole-body thermal imaging image by the control module 30 includes: and extracting a body shape characteristic diagram of the treatment object from the whole body thermal imaging image by using a human body shape characteristic extraction network.
The human body shape feature extraction network is obtained by training based on a plurality of training samples and the labeling information of the training samples, the training samples are human body thermal imaging images, the labeling information of the training samples is one or more known attributes representing human body shape features, and three attributes of height, weight and shape classification of human body objects in the human body thermal imaging images are used in the embodiment of the invention.
When the human body shape feature extraction network is trained, in order to enable the human body shape feature extraction network to learn better human body shape feature extraction capability, the three classification networks can be respectively connected to the output end of the human body shape feature extraction network; the three classification networks are respectively used for predicting the height, the weight and the shape classification of the human body object in the training sample; in the training process, inputting a training sample into a human body shape feature extraction network, and extracting human body shape features from the human body shape feature extraction network so as to output a body shape feature diagram; the body shape characteristic graph respectively enters three classification networks, and the three classification networks respectively predict the height, the weight and the body shape classification of the human body object based on the body shape characteristic graph; then, calculating a loss value based on the difference between the three kinds of information predicted by the three classification networks and the labeling information of the training sample; inputting a plurality of training samples into the network in sequence by analogy to train so that the network learns the capability of extracting the human body shape features; and when the calculated loss value is smaller than the threshold value, separating the human body shape feature extraction network from the three sub-networks to obtain the trained human body shape feature extraction network.
In practical applications, the feature extraction network can be implemented by a plurality of convolutional layers, and the classification network can be implemented by a full connection layer and a softmax layer.
There are various ways in which control module 30 may extract lower limb temperature features from the whole body thermographic image. For example, in one implementation, the extracting manner for extracting the lower limb temperature characteristic may include: and filing and assigning pixels in the whole body thermal imaging image according to preset temperature grading gears to obtain a lower limb temperature characteristic diagram.
It can be understood that there is a significant difference between the background temperature and the human body temperature in the whole-body thermal imaging image, so that the background and the human body in the image can be distinguished by filing the amplitude of the pixels thereof through the temperature grading steps. Moreover, the background can be uniformly assigned to a temperature which is obviously different from the body temperature. Preferably, the temperature-grading step may include: the gear shift control system comprises a first gear below 35 ℃, a second gear between 35 and 36 ℃, a third gear between 36 and 37 ℃ and a fourth gear above 37 ℃.
In another implementation, the extracting manner for extracting the temperature characteristic of the lower limb may include: and carrying out human body image segmentation on the whole body thermal imaging image by using the image segmentation network model, deleting the background and the upper half body image in the whole body thermal imaging image according to the segmentation result, and then filing and assigning the pixels in the deleted whole body thermal imaging image according to the preset body temperature grading gear to obtain the lower limb temperature characteristic diagram.
It is understood that by deleting the background and the upper body image, only the lower body temperature data of the treatment target can be retained in the whole body thermal imaging image after the deletion processing. Therefore, the pixels in the deleted whole body thermal imaging image are filed and assigned by further utilizing body temperature grading gears, and a more accurate lower limb temperature characteristic diagram can be obtained. Illustratively, the body temperature grading gears may include: a first gear at 35.0-36.0 ℃, a second gear at 36.1-37.0 ℃, a third gear at 37.1-38 ℃, and a fourth gear at 38.1-41 ℃.

(1) Acquiring a plurality of reference feature vectors constructed in advance; each reference characteristic vector corresponds to a preset infrared treatment scheme;
(2) Respectively converting the body shape characteristic and the lower limb temperature characteristic into vector forms and splicing the vector forms together to obtain a test characteristic vector;
(3) And respectively calculating the similarity of the test characteristic vector and the plurality of reference characteristic vectors, and determining the infrared treatment scheme of the treatment object according to the infrared treatment scheme corresponding to the reference characteristic vector with the highest similarity.
In practical application, a large number of treatment objects can be shot with whole body thermal imaging images in advance, body characteristics are extracted from the whole body thermal imaging images according to the extraction mode of the body shape characteristics and the lower limb temperature characteristics, and characteristic vectors are formed; meanwhile, according to the body shape of a treatment object, such as fat and thin, tight or loose muscle and striae, average body surface temperature, body surface temperature of each joint of the lower limb and other factors, the comprehensive guidance opinions of a plurality of professional doctors are combined to provide an infrared treatment scheme with universality, and then the scheme is associated with the treatment object. Therefore, a large number of reference feature vectors and their respective infrared treatment plans can be obtained.
Fig. 2 (a) illustrates an example of an ir treatment for a subject with a fat body, loose skin striae, low body temperature, especially low hip and knee temperature. It can be seen that, because the body of the treated subject is fat and loose in the striae, the heat can enter the striae more easily, and the body surface temperature of the treated subject is low, the total infrared radiation power is relatively slightly high; in addition, the radiation power at the site is set higher because the knee joint temperature of the subject is lower.
FIG. 2 (b) illustrates an exemplary IR treatment regimen for a thin, tight striae, and high body temperature subject. It can be seen that the heat is not easy to enter the striae because the treated subject is thin and tight, and the body surface temperature is high, so the total infrared radiation power is relatively low; in addition, considering that the body is thin, the radiation power of the infrared physiotherapy lamp 40 at the knee joint and the ankle joint is higher than the total power, because the knee joint is close to Zusanli acupoints of the human body, and the ankle joint is close to Taixi, sanyinjiao and other acupoints of the human body, so that the radiation power at the two places is high, and the health care effect of warming and invigorating spleen and stomach and kidney yang can be achieved.
