Human body circumference measuring method based on multi-view vision system

Abstract

The invention provides a human body girth measurement method based on a multi-view vision system. The method comprises the following steps: constructing a GSS-PSPNet network model, and training the GSS-PSPNet network model by using a data set; building three groups of binocular stereoscopic vision systems to respectively shoot color images of the testee; segmenting a to-be-measured girth area of the color image; performing HSV color space analysis on the segmented image to obtain sub-data sets of different color categories; clustering the pixels in the sub-data set; performing stereo matchingon the segmented image by adopting an SURF method to obtain coordinates of the same recognition point in the left view and the right view; space coordinates of the recognition points are obtained, andthree-dimensional coordinates of the marking points in the unified coordinate system are obtained; projecting all the marking points to an XOZ plane and fitting, wherein the length of a fitting curveis the girth of the measured area. The device is simple in structure, can effectively eliminate measurement errors caused by the movement of a measured object, greatly simplifies the stereo matchingprocess, and effectively improves the matching precision.

Description

Technical field [0001] The present 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 moving in the direction of automation and digitization. Nowadays, simple garment design can no longer satisfy people's pursuit of individuality, and garment design will inevitably tend to be customized. Clothing fit is the main factor affecting the quality of customization. Therefore, accurate anthropometric measurements of different individuals must be performed first. 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 complicated and time-consuming, and the measurement error depends on the experience of different measurers. [...
