A method for automatic alignment and size judgment of virtual fitting clothing models in computer

Abstract

The invention discloses a method for automatic alignment and size judgment of virtual fitting clothes models in a computer. This method is mainly aimed at the 3D clothing model, through the three-dimensional graphics calculation of the clothing model and the human body model, to realize the automatic alignment of the clothing model and the human body model, and to judge whether the size of the clothing can be worn by the human body through simulation try-on, giving A try-on effect. The main steps of the method include judging the clothing model, automatically aligning the jacket model, automatically aligning the pants model, collision detection and processing, size judgment and giving the try-on result. The present invention can achieve the effect of automatic alignment for a certain type of clothing model, does not need to set parameters or perform manual adjustment, and has certain generality and practicability.

Description

technical field [0001] The invention belongs to the technical field of computer graphics, and in particular relates to a method for automatic alignment and size judgment of a virtual fitting clothing model in a computer. Background technique [0002] In recent years, virtual fitting has become a hot issue in the field of virtual reality. As online shopping becomes more and more popular today, the virtual fitting system can provide consumers with more convenient services. , Take off, change, and wear clothes one by one, and there is no need to queue for a long time. [0003] In the virtual fitting technology, an important link is to try on the clothes, and how to align the human body model and the clothing model in the process is the first step. In the current research situation at home and abroad, most of the two-dimensional clothing cut pieces are stitched on the three-dimensional human body model to form the initial shape of the three-dimensional clothing. , and finally ...

AI Technical Summary

Problems solved by technology

However, automatic alignment is not implemented in the alignment method here. The displacement vector, rotation angle, etc. here cannot be adapted to all clothing models. For different models, fine-tuning parameters must be added after global position alignment and local posture adjustment. , through continuous experimentation, to find the appropriate value of fine-tuning parameters

Therefore, such a method cannot achieve the effect of automatic alignment

[0007] To sum up, the disadvantages of the existing methods mainly include: using CAD clothing data to pre-set the position of the clothing pieces requires more CAD clothing data, but some feature points cannot be directly provided by the CAD system and need to be manually inserted, which cannot be achieved. To achieve the "automatic" effect, when using sewing force for sewing, it is easy to deviate from the movement track of the sewing point due to the influence of other forces at the sewing point; using 3D clothing models, different clothing models need to be used when aligning Multiple experiments to find suitable fine-tuning parameters for alignment are not universal, and at the same time, the "automatic" effect cannot be achieved
