Embodiment Construction

[0039] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0040] Such as figure 1 As shown, the present invention provides a kind of human body three-dimensional measuring method based on digital image, comprises the following steps:

[0041] (1) Use vector graphics software to draw a scale data table, and print out the scale data table to obtain the physical scale table;

[0042] Specifically, you can use vector graphics software (CorelDRAW) or CAD software to draw a scale data table with a maximum precision of 1CM (that is, the minimum scale is 1CM) with length*width=200CM*120CM, and print out the completed scale data table to obtain the real object Scale form.

[0043] (2) Use a digital camera to shoot the physical scale form, obtain the digital image of the physical scale form, and record the camera focal length and object distance when shooting;

[0044] Specifically, the physical sc...

Abstract

The invention provides a human body three-dimensional measurement method based on digital images. The method includes the steps that a high-precision scale data form is manufactured through the digital images, human body plane two-dimensional data are measured through the digital image of the front face of a human body, the digital images of the side faces of the human body and the scale form, the vital statistic cross section of the human body is obtained through a three-dimensional scanner, the outline of human body routine measurement is obtained by fitting the human body plane two-dimensional data and the vital static cross section of the human body, and therefore vital statistic data of the human body are obtained. The human body three-dimensional measurement method based on the digital images is achieved on the basis of a human body vital statistic cross section database and two-dimensional digital images and can be used for customization of haute couture, measurement time can be greatly shortened, measurement accuracy and efficiency can be improved, the body size tendency of the human body can be evaluated, and the method is higher in measurement speed, more convenient to operate and lower in measurement cost in comparison with a three-dimensional non-contact measurement method.

Description

technical field [0001] The invention belongs to the field of three-dimensional measurement of human body, in particular to a method for three-dimensional measurement of human body based on digital images. Background technique [0002] With the requirements of people's clothing personalized design, clothing tailor-made has gradually entered the field of garment production, in which the anthropometric system is the basic work and key technology for realizing electronic tailor-made and establishing a human body shape database. Since the mid-1970s, it has gradually become an important research topic of clothing digital technology. In the development process of more than 30 years, it has roughly experienced three stages: from manual measurement to computer-aided measurement, from contact measurement to non-contact measurement, from two-dimensional to three-dimensional, and to automatic measurement and computer-based measurement, The direction of processing and analysis develops...
