Non-contact heart rate monitoring device and method based on speech interaction

Abstract

The invention relates to a non-contact heart rate monitoring device and a method based on voice interaction. The device comprises a voice input module, a voice recognition module, a voice broadcastingmodule, a video input module, an information inquiry module and a remote communication module. The method steps are: receiving voice commands from a user, the speech recognition module converts it into a character instruction, and then the character data analysis module analyzes whether the character instruction is a heart rate measurement, heart rate detection, information inquiry, remote call instruction, and if so, runs the module analyzed by the character data analysis module to execute the corresponding heart rate measurement, heart rate detection, information inquiry, and remote call functions. The speech recognition module converts the character instruction into a character instruction, and the character data analysis module analyzes whether the character instruction is a heart rate measurement, heart rate detection, information inquiry, and remote call instruction. The invention combines the voice technology and the non-contact heart rate measurement technology, realizes the whole-day heart rate monitoring by enlarging the small motion change in the video, and provides a more stable heart rate measurement method and a more convenient heart rate monitoring device.

Description

technical field [0001] The present invention belongs to the technical field of physics, and further relates to a non-contact heart rate monitoring device and method based on voice interaction in the technical field of electronic equipment. The device can be used to measure the heart rate of a human body in a non-contact condition, and provide heart rate monitoring for users. Background technique [0002] As one of the most important physiological parameters of the human body, heart rate is the focus of people's attention, and heart rate is often monitored by some devices. The theoretical basis of non-contact heart rate monitoring is that the beating of the heart will cause the human body to follow the heartbeat to produce tiny periodic movements. People can use digital image processing technology to amplify this tiny periodic movement, and analyze the amplified data to extract heart rate value.
