Problems solved by technology

[0004] Aiming at the problem that the traditional intelligent terminal can not effectively identify the outline of the human body or object and the position of the measurement point, the present invention proposes a method using a hybrid grabcut, ostu, etc. and a heuristic method to determine the position of the key points of the human body, and then determine the basic parts of the human body method of pixel location

Embodiment Construction

[0025] Embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] 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:

[0027] Such as figure 1 As shown, key point identification and measurement include the following steps:

[0028] Step S110: Determine the key point calculation target; according to the target of the human body profile measurement, classify the human body profile according to the age, gender, and body shape elements of the human body, and determine the screening range of key points for different levels of human body profile measurement;

[0029] Step S120: Determine the key points of the human body contour; use a combinatio...

Abstract

The invention provides a human body contour key point and key part recognition method based on grading, the method comprises two stages of key point recognition and measurement and key part recognition, and the key point recognition and measurement stage comprises the following steps: determining a key point calculation target; determining key points; calculating the pixel size by connecting the key points; and calculating an actual size according to the pixel size. The key part identification stage comprises the following steps: determining an approximate area of a detected human body contour key part; determining a key part segmentation target; segmenting key parts of the human body contour; and performing the key portion segmentation and confirmation. The contour of the human body can be effectively identified, the human body contour measurement key points and the positions of the key parts are determined through a heuristic method, and accurate size measurement is facilitated.

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 ...
