Embodiment Construction

[0055] The method for predicting the anthropometric data refers to a method for predicting the measurement data of the human body to be measured by using two non-depth pictures and the height and weight information of the human body to be measured.

[0056] Such as figure 1 As shown, the equipment for realizing the method of the present invention includes a scale, an ultrasonic height measuring instrument, and a 150-degree wide-angle camera with 5 million pixels.

[0057] Such as Figures 2 to 8 As shown, the method for predicting anthropometric data includes the following steps:

[0058] One) build a model library; the model library is made up of a plurality of human body models and the measurement data of multiple positions of each human body model, and building a model library includes the following steps,

[0059] Step 1) set up a three-dimensional human body virtual model library: generate a standard posture human body three-dimensional virtual model library of any size...

Abstract

The invention belongs to the field of data measurement, and particularly relates to a method of generating a human body three-dimensional data model library, so as to solve problems that data in the existing database are imperfect, the acquisition range is small, the acquisition is single, and the data accuracy is poor. The method comprises the following steps: 1) a human body three-dimensional virtual model library is built; 2) the weight and the offset of a virtual model posture label are obtained through learning; 3) a PCA main feature value is acquired; and 4) the model data are calculated. The method can build the human body database in a low cost, high precision and high efficiency mode, the measurement time can be greatly shortened, the measurement precision and the efficiency are improved, and the posture trend of the human body can be evaluated.

Description

technical field [0001] The invention belongs to the field of data measurement, and in particular relates to a method for generating a human body three-dimensional data model library. Background technique [0002] As technology develops, obtaining 3D anthropometric data is a necessity in many industries. For example, it is used in the medical field to monitor changes in body volume due to renal failure or to evaluate changes in patient body images to ensure the success of surgery. In addition, being able to generate accurate body characteristics and measurement data is also beneficial to the clothing industry. Accurate body measurements will benefit clothing manufacturers or retailers to communicate with customers and benefit online purchases. [0003] Anthropometric system is the basic work and key technology to realize electronic tailoring and establishment of human body shape database. In the development process of more than 30 years, it has roughly experienced three sta...
