Abstract

The invention relates to the field of artificial intelligence, and particularly discloses a heart rate estimation method, device and equipment based on image recognition and a storage medium. The method comprises the steps: acquiring multiple frames of scene images, determining multiple frames of skin images according to the multiple frames of scene images, and extracting skin color change signalsfrom the multiple frames of skin images; obtaining a current scene corresponding to the multiple frames of scene images, and selecting a filtering interval corresponding to the current scene according to the current scene; filtering the skin color change signal in the filtering interval to obtain a filtered skin color change signal; and determining the heart rate according to the wave crest of the filtered skin color change signal. According to the invention, the half-frequency phenomenon can be inhibited, and the heart rate identification accuracy is improved. In addition, the invention alsorelates to the blockchain technology, and the scene image can be stored in a blockchain node.

Description

technical field [0001] The present application relates to the field of feature extraction, in particular to a heart rate estimation method, device, equipment and storage medium based on image recognition. Background technique [0002] At present, photovolume description methods can be used to extract biophysical signals of time-varying features such as heart rate and blood flow based on subtle changes in skin color that change with respiration and heartbeat cycles. However, limited by the laws of physics, when using the optical volume description method to identify signs such as heart rate, it will be affected by the half-frequency problem and cause heart rate calculation errors. [0003] Therefore, how to suppress the half-frequency phenomenon and improve the accuracy of heart rate recognition has become an urgent problem to be solved. Contents of the invention [0004] The present application provides a heart rate estimation method, device, equipment and storage medium ...
