Respiratory rate detection method and device, storage medium and electronic equipment

Abstract

The invention relates to a respiratory rate detection method and device, a storage medium and electronic equipment. The method comprises the following steps: acquiring at least two image groups, wherein each image group comprises a visible light image and a thermal image matched with the visible light image; extracting a first target area in the visible light image, wherein the first target area points to a breathing area of a target object; determining a second target area corresponding to the first target area in the thermal image; determining temperature information corresponding to each second target area on the basis of the thermal image, wherein the temperature information periodically changes along with respiration of the target object; and determining the breathing rate of the target object according to the temperature information. According to the method, the respiratory rate detection result can be obtained under the condition that the target object is not contacted, non-contact detection is achieved, and the good detection speed and detection accuracy are achieved.

Description

technical field [0001] The present disclosure relates to the technical field of computer vision, and in particular to a method, device, storage medium and electronic equipment for detecting respiration rate. Background technique [0002] Respiration rate is the breathing frequency, which is a relatively important physiological parameter, which can usually be used to analyze the health status of the human body and evaluate the emotions of the human body. The equipment usually used to detect the respiration rate is a breathing belt or an electronic contact respiration detector. This type of respiration rate detection device detects the respiration rate through direct contact with the detected object, but the applicable scenarios of this contact detection method limited. For example, for scenes with isolation requirements, where the detected object is required to be non-aware, this type of breathing rate detection equipment cannot be used, that is to say, related technologies ...
