Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual clothing selection methods are limited by the need for static subjects, complex hardware, high computational complexity, and inability to provide realistic three-dimensional fitting, especially in terms of body type, leading to inaccurate clothing fits.
Innovation Solution
A method using two photographic images of a subject wearing an elastic template with reference markings to create a virtual three-dimensional body template, allowing for accurate anthropometric data calculation and virtual fitting of clothing that accounts for individual body type, size, and shape, facilitating interaction between clothing manufacturers and consumers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If scanning is performed using a graphically segmented elastic covering and video camera at fixed distance, then body measurements can be obtained, but the body must be kept static during scanning and only one body can be scanned at a time
Solution Approach 1:
The patent uses a two-dimensional photographic image as a copy of the three-dimensional body, eliminating the need for complex scanning hardware and static positioning. The elastic template with reference markings is captured in a single photograph, creating a digital copy that can be processed computationally to extract measurements without requiring the subject to remain stationary or undergo multi-angle scanning.
Solution Approach 2:
The patent replaces the mechanical scanning system (video camera on fixed orbit around static body) with a photographic imaging system. Instead of mechanically moving a camera around a static body, a single photograph is taken with the subject in natural pose, and computational methods are used to extract three-dimensional measurements from the two-dimensional image combined with elastic template deformation analysis.
2Measurement precision
If three-dimensional body shape is modeled using computational method with infrared-sensitive camera, then body measurements can be obtained, but computational complexity is high and expensive specialized measuring hardware is required
Solution Approach 1:
The patent uses a standard photographic image as a copy of the body, replacing expensive infrared-sensitive cameras and complex computational modeling. The elastic template with reference markings serves as an auxiliary copying mechanism that can be captured by ordinary photographic equipment, and the measurements are derived through analysis of template deformation rather than direct three-dimensional scanning.
Solution Approach 2:
The patent employs a simple, inexpensive elastic template with printed reference markings instead of expensive specialized measuring hardware. The template is a disposable or reusable flexible object that can be manufactured at low cost and used with standard photographic equipment, eliminating the need for costly infrared cameras and complex measurement systems.
3Shape
If three-dimensional modeling is performed by combining and projecting shape from two-dimensional photographic images, then body shape can be reconstructed, but large amounts of data requiring compression and excessive computer processing power are required
Solution Approach 1:
The patent extracts only the essential measurement information needed for clothing selection from the photographic image, rather than processing and storing large amounts of three-dimensional body data. By focusing on extracting linear dimensions and body proportions from the elastic template deformation pattern, the system avoids the computational burden of full three-dimensional reconstruction while still providing accurate clothing fit information.
Solution Approach 2:
The patent performs partial three-dimensional reconstruction by only calculating the specific body measurements needed for clothing fitting, rather than reconstructing the entire three-dimensional body shape. This selective extraction of relevant dimensional data reduces computational requirements while maintaining accuracy for the intended application.
4Adaptability or versatility
If virtual selection is implemented using existing methods, then clothing selection can be performed online, but the virtual model does not account for individual body type leading to inaccurate clothing fits
Solution Approach 1:
The patent applies local quality by using an elastic template with reference markings that deforms according to the specific contours of an individual's body. Unlike generic virtual fitting models, the template adapts to local body shape variations, and the reference markings provide localized measurement data that captures individual body type characteristics, enabling accurate clothing fit prediction for diverse body shapes.

AI summary
The claimed method for virtually selecting clothing is carried out on the basis of at least two photographs of the body of a subject dressed in an elastic template having reference markings; a computer processes the markings, and produces a three-dimensional mathematical model of the body of the subject, which is input into a database using an identification number pertaining to same; the database is accessible by the buyer, the seller and the clothing manufacturer. The method is applicable for selecting clothing for humans, and also for animals. Standard-shape graphical elements are applied, in a regular pattern, to an elastic covering which is worn on the body, and the relationship between said elements is used as a basis for forming a three-dimensional model of the body. Models of clothing, which correspond to the parameters of the three-dimensional model of the subject, are selected from clothing databases. A consumer receives, on the screen of their computer, three-dimensional images of their body in the selected clothing models.
