Virtual Foot Clothing Fitting with Posture-Aware Pattern Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When purchasing foot clothing online, users cannot intuitively feel the effect of wearing the clothing, leading to inappropriate choices, and in-store shopping for foot clothing is inconvenient for trying on.
Innovation Solution
A method and apparatus for simulating clothing changing, which involves extracting a foot image from a target image, generating foot posture information, and superimposing a clothing pattern onto the foot image based on the posture information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users shop online for foot clothing, then convenience is improved, but the ability to intuitively feel the clothing effect deteriorates
Solution Approach 1:
The patent creates a virtual copy of the foot (3D model) and superimposes the clothing pattern onto this copy to simulate the clothing effect. This allows users to perceive how clothing looks on their feet without physically trying it on, thus maintaining online shopping convenience while providing visual feedback about clothing fit and appearance.
Solution Approach 2:
The patent introduces an intermediary system consisting of 3D foot models and image processing technology as a mediator between the user and the clothing. This intermediary enables the user to visualize the clothing effect by superimposing patterns onto the virtual foot model, bridging the information gap in online shopping.
2Loss of information
If users shop in convenience stores or shopping arcades, then clothing trying is possible, but convenience and time efficiency deteriorate
Solution Approach 1:
The patent uses a 3D virtual copy of the foot to simulate clothing trying. Users can input their foot image, and the system generates a virtual model to display how different clothing patterns would look, eliminating the need to physically visit stores and try on multiple items, thus saving time while providing accurate clothing effect visualization.
Solution Approach 2:
The patent performs preliminary action by pre-processing the user's foot image to extract foot posture information and generate a 3D foot model before the actual clothing selection process. This preliminary preparation enables rapid simulation of various clothing options without requiring the user to spend time in physical stores.
3Productivity
If clothing pattern is superimposed without foot posture information, then processing speed is improved, but positioning accuracy deteriorates
Solution Approach 1:
The patent performs preliminary action by extracting foot posture information from the user's foot image before superimposing the clothing pattern. This pre-extraction of posture data (including foot orientation, angle, and position) enables accurate positioning of the clothing pattern while maintaining efficient processing, as the posture information is prepared in advance and used directly during the superposition step.
Solution Approach 2:
The patent applies parameter changes by adjusting the positioning parameters of the clothing pattern based on the extracted foot posture information. The system modifies parameters such as translation vectors and rotation angles according to the foot's actual posture, ensuring accurate placement of the clothing pattern while maintaining computational efficiency through optimized parameter transformation.
