Problems solved by technology

However, related prediction products do not consider the individual differences between the sample library and users when building the prediction model, that is, the sample library is preset in advance, and the prediction model constructed by extracting feature vectors from samples is universal and lacks the ability to directly contact users. Specificity, which can easily lead to bias in blood pressure prediction results

Embodiment

[0041] A blood pressure prediction system based on face images, including a sample collector and a mobile terminal.

[0042] The sample collector includes: a head-mounted image collection device and a blood pressure measurement device.

[0043] Among them, such as figure 1 As shown, the head-mounted image acquisition device includes a top bracket 1, a first strap 2, a tab 3, a bottom bracket 4, a second strap 5, a card slot 6, a neck fixing strap 7, a bracket 8 and a camera 9;

[0044] The jacking 1 is a cover-shaped hard bracket, and the shape of the jacking 1 is adapted to the central position of the human head, and different models (size, radian) can be set to meet the needs of users with different head shapes. It is advisable to choose the size of the jacking 1 so that no displacement will occur when lying flat. The left and right sides of the top bracket 1 are symmetrically provided with strap fixing holes.

[0045] One end of the first strap 2 is fixed at the strap fi...

Abstract

The invention discloses a blood pressure prediction system based on face images. The system comprises a sample collector and a mobile terminal; the sample collector comprises a head-mounted image collection device and a blood pressure measurement device; the mobile terminal comprises a to-be-predicted image collector, an image collection control module, an image processing module, a feature vectorextraction module, a blood pressure prediction model construction module, a blood pressure prediction module and a blood pressure file database. The sample face image for constructing a prediction model and the face image for predicting the blood pressure are collected through two image collection modes respectively, the difference between a sample and an actually-predicted individual is eliminated, and the sample is more conveniently collected.

Description

technical field [0001] The invention relates to the technical field of blood pressure detection, and more specifically relates to a blood pressure prediction system based on human face images. Background technique [0002] For hypertensive patients, blood pressure monitoring helps to grasp the trend of blood pressure changes, and then provides a reference for disease prevention, diagnosis and control. With the development of science and technology, blood pressure monitoring technology is becoming more and more intelligent and simple. [0003] At present, there are many methods for predicting blood pressure through the features of face images, all of which need to build a prediction model based on a sufficient number of samples. However, related prediction products do not consider the individual differences between the sample library and users when building the prediction model, that is, the sample library is preset in advance, and the prediction model constructed by extract...
