Problems solved by technology

[0002] Respiration rate is an important physiological data used to analyze information such as human health status and emotions. The respiration rate measurement method in related technologies is usually contacted, such as the commonly used breathing belt, which needs to connect the subject to the breathing belt , but the application scenarios of this contact measurement method are limited
For outdoor scenes, scenes with isolation requirements and other scenes that require non-contact measurement, this contact measurement method cannot be used. Therefore, related technologies are difficult to meet the demand for non-contact measurement of respiration rate

Abstract

The invention relates to a respiratory rate detection method and device based on thermal imaging and electronic equipment. The method comprises the following steps: acquiring at least two thermal images comprising the contour of a target object rendered based on the temperature information of the target object; extracting a target area in each thermal image based on a neural network; extracting temperature information corresponding to each target area; the temperature information periodically changing along with respiration of the target object, and determining the respiration rate of the target object according to the extracted temperature information. According to the method and the device, the breathing rate of the target object can be determined by analyzing the thermal image shot by the thermal imaging camera, so that the breathing rate detection result is obtained under the condition that the target object is not contacted, non-contact detection is realized, the blank of a non-contact detection scene is filled, and the method and the device have good detection speed and detection accuracy.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to a thermal imaging-based respiration rate detection method, device and electronic equipment. Background technique [0002] Respiration rate is an important physiological data used to analyze information such as human health status and emotions. The respiration rate measurement method in related technologies is usually contacted, such as the commonly used breathing belt, which needs to connect the subject to the breathing belt , but the applicable scenarios of this contact measurement method are limited. For outdoor scenes, scenes with isolation requirements and other scenes that require non-contact measurement, this contact measurement method cannot be used. Therefore, it is difficult for related technologies to meet the demand for non-contact measurement of respiration rate. Contents of the invention [0003] In order to solve at least one technical proble...
