Title:
BMI EVALUATION METHOD AND DEVICE, AND COMPUTER READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/103417
Kind Code:
A1
Abstract:
The present invention relates to the technical field of intelligent decision making, and provides a BMI evaluation method and device, and a computer readable storage medium. The method comprises: collecting sample face image data, the sample face image data comprising a BMI value (S10); training the sample face image data by adopting a convolutional neural network to obtain a training model (S20); obtaining a face image to be detected, positioning face key feature points of said face image, and obtaining the face key points (S30); performing face contour extraction according to the face key points to obtain a face contour (S40); performing equal-proportion stretching on the face contour according to a perspective view angle to obtain a preprocessed face image (S50); and performing category prediction on the preprocessed face image according to the training model to obtain an evaluation BMI value of said face image (S60). By means of the method, the BMI value can be rapidly detected in real time, and the BMI measurement difficulty of a measurer is reduced.
