Embodiment 1

[0023] Embodiments of the present invention provide a non-contact pain recognition method for children, such as figure 1 shown, including the following steps:

[0024] Step S1: Continuously detect the facial micro-expression and body posture of the target baby through the camera, and continuously detect the heartbeat rate and breathing rate of the target baby through radar waves.

[0025] Step S2: Calculate the current pain index of the target baby according to the detected facial micro-expression, body posture, heart rate, breathing rate and preset pain index calculation rules.

[0026] In this example:

[0027] The facial micro-expressions and body postures that can be measured by the camera are A1, A 2 kind;

[0028] The heartbeat frequency range and respiratory frequency range that can be measured by radar waves are divided into A 3 Section, A 4 part;

[0029] Pain index calculation rules include:

[0030] The first sub-rule corresponding to facial micro-expression,...

Embodiment 2

[0043] An embodiment of the present invention provides a non-contact pain recognition system for children, based on a non-contact pain recognition method for children provided in Embodiment 1, such as figure 2 shown, including:

[0044] The camera unit 10 is used to continuously detect the facial micro-expressions and body gestures of the target baby;

[0045] The radar wave unit 11 is used to continuously detect the heart rate and breathing rate of the target baby;

[0046] The calculation unit 12 is used to calculate the current pain index of the target baby according to the detected facial micro-expression, body posture, heart rate, breathing rate and preset pain index calculation rules;

[0047] Judging unit 13, used to judge whether the current pain index of the target baby is not less than the preset early warning threshold;

[0048] The warning unit 14 is configured to send a warning signal when the current pain index of the target baby is not less than the preset wa...

Abstract

The invention relates to a non-contact child pain recognition method and system, and the method comprises the steps: continuously detecting the facial micro-expression and body posture of a target infant through a camera, continuously detecting the heartbeat frequency and respiratory frequency of the target infant through radar waves, and further, according to the detected facial micro-expression, the body posture, the heartbeat frequency, the breathing frequency and a preset pain index calculation rule, obtaining the current pain index of the target infant through calculation, then judging whether the current pain index of the target infant is not smaller than a preset early warning threshold value or not, and if the current pain index of the target infant is not smaller than a preset early warning threshold value,sending out an early warning signal; otherwise, not sending out the early warning signal. The camera and the radar waves are responsible for detection work, uninterrupted detection can be achieved, medical workers are liberated, the emergency situation of the baby cannot be missed, the baby can be taken care of more comprehensively, in addition, the subjectivity of manual scoring is eliminated when the pain index is calculated, and the evaluation result is more reliable.

Description

technical field [0001] The present invention relates to the field of smart medical technology, and more specifically, to a non-contact pain recognition method and system for children. Background technique [0002] Babies need a lot of attention while they are in an incubator or recovering from anesthesia. However, when medical resources are in short supply, medical staff can only regularly check on the baby's condition, scoring and evaluating according to the Glasgow Coma Scale (GCS). Using the aforementioned method, it is easy to miss the emergency situation of the baby, and it also increases the workload of the medical staff, and the medical staff is relatively subjective in the evaluation process, and the fluctuation of the evaluation result is large. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a non-contact pain recognition method for children and a non-contact pain recognition system for children aiming...
