A method of measuring human body circumference based on multi-eye vision system

Abstract

The present invention proposes a kind of human body girth measurement method based on multi-eye vision system, and its steps are as follows: construct GSS-PSPNet network model and utilize data set to train; Build three groups of binocular stereo vision systems and take the color image of the person under test respectively ;Segment the area to be measured in the color image; analyze the HSV color space of the segmented image to obtain sub-datasets of different color categories; cluster the pixels in the sub-dataset; use the SURF method to perform stereo matching on the segmented image , to obtain the coordinates of the same marker point in the left view and right view; to obtain the spatial coordinates of the marker point, to obtain the three-dimensional coordinates of the marker point in the unified coordinate system; to project all the marker points to the XOZ plane and fit them, and to fit the length of the curve is the circumference of the area to be measured. The invention has a simple structure, can effectively eliminate the measurement error caused by the motion of the measured object, greatly simplifies the three-dimensional matching process, and effectively improves the matching accuracy.

Description

technical field [0001] The invention relates to the technical field of multi-eye stereo vision, in particular to a method for measuring human body circumference based on a multi-eye vision system. Background technique [0002] With the rapid development of information technology, clothing design is developing in the direction of automation and digitization. Nowadays, simple ready-made clothing design can no longer satisfy people's pursuit of individuality, and clothing design must tend to be customized. Clothing fit is the main factor affecting the quality of customization. Therefore, accurate anthropometric measurements of different individuals must first be performed. The traditional anthropometric measurement is to manually measure the human body size with a tape measure, which has strong controllability and flexibility. However, the manual measurement process is complex and time-consuming, and its measurement error depends on the experience of different measurers. ...
