Method for generating customized human body model according to human body measured dimension data based on instances

Abstract

The invention provides a human body modeling technique conforming to a customized human body size and is applied to the field of three-dimensional test systems and computer-aided design garments. The method mainly comprises three steps of 1, extracting 26 human body measurement dimensions from an instance model to form a dimension set, performing statistical analysis of the relationship between the dimensions, and dividing the instance model into 16 rigid parts; and 2, performing block analysis of statistical information of human body shapes, wherein the linear regression method is used in the statistical analysis of the mapping relation between the human body shape to the dimension data and a new method for accurately generating a customized model is used, and leaning the linear mapping relation between the local deformation parameter and the semantic parameter of each human body part; and 3, performing human body modeling according to an input dimension, and finely tuning an initial model to enable it to conform to the input dimension parameter after a new human body model is obtained. The method can accurately generate a customized human body model for virtual fitting with less distortion.

Description

An example-based method for generating personalized human body models from anthropometric size data 1. Technical field The invention relates to a method for individually establishing a virtual human body model in three-dimensional fitting software, which is applied to the fields of three-dimensional fitting systems and computer-aided clothing design. 2. Background technology With the continuous development of society and economy in recent years, people began to pursue personalized clothing, and personalized clothing design has gradually become more popular with the public. Users want to design custom clothing that fits their body shape according to their body shape, and avoid the trouble of on-site fitting, so designers need to use computers to create human models of corresponding sizes for users of different body types to simulate the effect of real clothing wearing. With the gradual rise of this field, human body modeling that conforms to the user's body characteristics ...

AI Technical Summary

Problems solved by technology

Using a scanner to directly scan the customer's human body has high accuracy, but requires professional equipment and high cost; using the user's size parameters as input to generate a personalized model method produces a large difference between the human body model and the actual human body, which affects the accuracy of the three-dimensional fitting end use effect
