Embodiment Construction

[0039] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0040] A method for identifying key points and key parts of human body contours based on grading described in the present invention uses an intelligent terminal to take images of human body contours. The processing method of the present invention includes two stages: key point recognition and measurement, and key part recognition:

[0041] Such as figure 1 As shown, key point identification and measurement include the following steps:

[0042] Step S110: Determining the key point calculation target: according to the target of the human body profile measurement, the human body profile is classified according to the age, gender, and body shape elements of the human body, and the screening ranges for the key points of the human body profile measurement of different levels are determined respectively;

[0043] Step S120: Determine the key points of the hu...

Abstract

The present invention provides a method for identifying key points and key parts of human body contour based on grading. The method includes two stages: key point identification and measurement, and key part identification. The key point identification and measurement stage includes the following steps: Key point calculation target determination; key point determination; connect key points to calculate pixel size; calculate actual size based on pixel size. The key part identification stage includes the following steps: determine the approximate area of ​​the key part of the measured human body contour; determine the segmentation target of the key part; segment the key part of the human body contour; segment and confirm the key part. The invention can effectively identify the contour of the human body, and determine the positions of key points and key parts of the human body contour measurement through a heuristic method, so as to facilitate accurate size measurement.

Description

technical field [0001] The invention relates to a classification-based identification method for key points and key parts of human body contours, and belongs to the technical field of measurement using intelligent terminals. Background technique [0002] With the popularization of smart terminals such as smartphones and tablet computers, technologies related to human height measurement and object size measurement based on images and videos taken by smart terminals continue to develop. For example, patents such as an intelligent height tester (application number: CN10387677.9), a method for measuring the plane size of an object by using the camera function of a mobile phone (application number: CN201510521937.8) and other patents propose a method for measuring the height of a human body and the plane size of an object. A method of measuring the length of a dimension or the plane size of an object. [0003] The above-mentioned size measurement method based on the intelligent ...
