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 pie

Embodiment Construction

[0086] Method of the present invention can be divided into six big steps, as figure 1 As shown, it includes: step 1 to judge the clothing model; step 2 to automatically align the top model; step 3 to automatically align the pants model; step 4 to detect and process collisions; step 5 to judge the size; step 6 to give the try-on results.

[0087] The specific steps of the present invention are as follows: Step 1, load the clothing model, such as reading the clothing model file "men's short-sleeved shirt. The type of the clothing model is marked as 0, if it is a pants model, the type of the clothing model is marked as 1, the information of the clothing model is read, and an adjacency list is constructed for it. The clothing model is a three-dimensional clothing model. According to the known clothing model type, if it is a jacket model, then perform step 2, if it is a trousers model, then perform step 3; the information of the clothing model includes vertex information and triang...

Abstract

The invention discloses a computer virtual fitting clothing model automatic alignment and size judgment method. The method mainly aims at a 3D clothing model, automatic alignment of the clothing model and a human body model is realized by three-dimensional graphical calculation of the clothing model and the human body model, and whether the size of clothing is fit on the human body can be judged via simulation fitting and a fitting effect is given. The main steps of the method comprise judgment of the clothing model, automatic alignment of an upper clothing model, automatic alignment of a trouser model, collision detection and processing, size judgment and giving of the fitting result. The effect of automatic alignment of a certain type of clothing model can be achieved with no requirement for given parameters or manual judgment so that the method has certain generality and practicality.

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 ...
