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.

[0120] When executing enter:

[0121] A 3D mesh entity selected by the user.

[0122] Calculation or processing method:

[0123] Generate a feature mesh object with the name of the input name, and use the selected mesh entity data as the object's geometry data. And add this feature grid to the human body model, if it already exists in the model, it will overwrite the existing feature grid.

Embodiment 2

[0125] A2: Split feature mesh objects by feature planes.

[0126] When creating enter:

[0127] 1) The user selects the feature grid object to be divided or enters the name of the feature grid object to be divided.

[0128] 2) After the feature mesh is split, the names of the two feature mesh objects generated above and below the split plane.

[0129] Enter at execution time: None

[0130] Calculation or processing method:

[0131] 1) Find the feature mesh object to be segmented in the human body model.

[0132] 2) Find feature plane objects for segmentation in the human body model.

[0133] 3) Segment the 3D grid data in the feature grid object, and use the two 3D grid data on the upper and lower sides of the divided plane as geometric data to generate two upper and lower feature grid entity objects respectively, and add them to the human body model middle.

Embodiment 3

[0135] B1: Generate feature point objects based on the points selected by the user.

[0136] When creating enter:

[0137] The name of the feature point object to generate, such as "Point_BP".

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...
