Programmable three-dimensional human body modeling and human body measurement system and method thereof

Abstract

A programmable three-dimensional human body modeling and human body measurement system and a method thereof relates to three-dimensional model or image operation which is used for computer graphics and especially suitable for human body measurement and clothes CAD based on a human body characteristic. A human body model definition unit is connected to a three-dimensional human body grid database and a human body characteristic model database. A human body characteristic information algorithm tool library management unit is connected to a human body characteristic model database and a basic algorithm tool library. A human body measurement rule template management unit is connected to the basic algorithm tool library and a human body measurement rule database. A three-dimensional human bodygrid data analysis measurement unit is connected to the three-dimensional human body grid database and the human body measurement rule database. A user can define a human body characteristic identification rule and a dimension measurement rule through man-machine interaction operation. Simultaneously, the measurement rule defined by the user can be applied to different individualities. Three-dimensional human body scanning input, intelligent human body characteristic point identification, human body part dimension measurement and three-dimensional virtual human form construction are combined together.

Description

technical field [0001] The invention relates to the operation of three-dimensional models or images used for computer graphics, and is especially suitable for a programmable three-dimensional human body modeling and human body measurement system and method for body measurement and clothing CAD based on human body features. Background technique [0002] Three-dimensional human body measurement technology and human body feature information extraction technology are the technical basis of three-dimensional clothing CAD system. Although the 3D scanning equipment currently developed and used can provide high-quality human body models, the 3D anthropometric system has many advantages over traditional measurement techniques and tools, such as short scanning time, high accuracy, and multiple measurement parts. However, most measuring devices only provide point cloud data without human body feature information, and cannot directly obtain the human body feature information required by...

Problems solved by technology

However, due to the influence of various factors such as age, gender, race, and region when the human body grows, there are great differences in body shape among individuals. table geometry is inconsistent

Therefore, the recognition results of the existing measurement system for the characteristics of the human body will be quite different from the measurement characteristics calibrated during manual measurement, which will cause a large difference between the automatically measured size and the manual measurement. One of the reasons for the mature application in the industry

[0006] 2) Human body feature recognition methods and rules, size measurement rules cannot be freely designed

[0007] In the existing measurement system, the identification rules of human body feature points and the geometric rules of size measurement conversion are all predefined by the software itself, and users cannot design feature point identification and measurement rules according to their own needs.

Even though some systems allow users to measure some measurement dimensions through the manual measurement function provided by the system, for different individuals, these manual measurement processes need to be repeated to complete the measurement

[0008] 3) The measurement system has restrictions on the body measurement posture

[0009] The existing three-dimensional measurement system recognizes the human body in a specific posture because of its feature point recognition rules and size measurement rules. Therefore, after changing the posture, the measurement system will not be able to correctly identify and measure the human body features and dimensions.
