Virtual Apparel Fitting via Body Garment Fit Point Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current online retail clothing shopping lacks reliable size selection options, leading to high return rates due to poor fit, as standard size information is no longer a reliable indicator of fit accuracy.
Innovation Solution
A virtual apparel fitting system that allows users to upload images or take photos to create a 2D or 3D model of themselves, align with garment images on a mannequin, and generate a fit index, enabling them to virtually try on garments and select the best fit based on their body shape and preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If standard size information is used for online garment selection, then the shopping process is simple and quick, but the fit accuracy deteriorates significantly
Solution Approach 1:
The system creates a virtual copy of the user's body through 2D or 3D modeling from uploaded images or questionnaire data. This virtual body model serves as an accurate replica that can be used to simulate garment fitting without requiring the user to physically try on clothes, thereby maintaining ease of operation while dramatically improving fit accuracy.
Solution Approach 2:
The patent replaces the mechanical process of physically trying on garments with a digital simulation system. Instead of using physical fitting, the system uses computational algorithms to render virtual images of the user wearing garments, substituting the mechanical trial process with digital modeling and rendering to achieve both simplicity and accuracy.
2Measurement precision
If virtual fitting technology is implemented, then fit accuracy is improved, but device complexity increases
Solution Approach 1:
The system divides the complex virtual fitting process into separate functional modules: (1) body model creation from images or questionnaires, (2) garment digital modeling, (3) garment mapping to body model, and (4) virtual rendering. This segmentation allows each component to be developed and optimized independently, managing overall system complexity while maintaining high fit accuracy.
Solution Approach 2:
The patent introduces an intermediary garment mapping process that bridges the body model and the virtual garment display. This intermediary step involves creating a deformable mesh that can be shaped to conform to the user's body geometry, serving as a mediator that simplifies the complex interaction between the body model and garment rendering while maintaining accuracy.
3Loss of information
If multiple garments are virtually tried on, then informed purchasing decisions are enabled, but time consumption increases
Solution Approach 1:
The system performs preliminary actions by pre-creating the user's virtual body model and pre-processing garment data before the user needs to make purchasing decisions. The body model is generated once from initial images or questionnaire data, and this model can then be used to rapidly simulate multiple garment fits without repeating the entire modeling process for each garment, thereby reducing time consumption while enabling comprehensive evaluation.

AI summary
Embodiments disclosed herein include virtual apparel fitting systems configured to perform methods comprising generating a plurality of garment images for a garment based on a single digital image of the garment, wherein each garment image corresponds to a different size of the garment; generating a user image for a user based on a digital photograph of the user; receiving a selection comprising the garment; in response to receiving the selection comprising the garment, generating an image of the user wearing the garment based on an alignment of garment fit points in one garment image of the plurality of garment images with corresponding user fit points in the user image; and transmitting the image of the user wearing the garment to the user's computing device for display in a graphical user interface.
