Abstract

The invention relates to a three-dimensional human body measurement method by using a single camera. The three-dimensional human body measurement method comprises the following steps: arranging a set of mirror combination system in front of the single camera to further form a monocular vision sensor with the camera, wherein the monocular vision sensor can simultaneously acquire front and side images of a human body to be measured on the left and right planes of the camera; obtaining a front outline and a side outline of the human body by image processing such as threshold segmentation, edge detection and the like; determining the characteristic points and lines of the human body measurement; calculating to obtain the width and thickness data of the parts of the human body; and performing three-dimensional curve-fitting by regression analysis. The three-dimensional human body measurement method by using the single camera has the advantages of simple device, convenient operation, low measurement cost, and better practical value and popularization prospect.

Description

technical field [0001] The invention belongs to the technical field of non-contact three-dimensional human body measurement, in particular to a three-dimensional human body measurement method using a single camera. Background technique [0002] In recent years, with the development of computer vision graphics, there are many applications in non-contact 3D human body. The Chinese patent "Automatic measurement system for three-dimensional structure data of the human body" (CN1084374) provides an automatic measurement system for three-dimensional structure data of the human body. The processing technology extracts the real outline of the human body from the image of the human body, and then performs comprehensive calculations on multiple real outlines of the human body to obtain the required three-dimensional data reflecting the three-dimensional structural characteristics of the human body. In the Chinese patent "a method of human body measurement and analysis" (CN1596827), a...
