Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for acquiring user figure parameters in personalized virtual fitting systems are either user-unfriendly, require expensive equipment, or are inaccessible due to high costs and limited availability, leading to inaccurate measurements and low popularization.
Innovation Solution
A method and device that automatically acquire accurate user figure parameters by processing a photo, using a parameterized three-dimensional human body model to match the user's profile, adjusting posture and height, and calculating figure parameters with a preset error tolerance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a flexible rule measurement method is used, then the user can measure their own figure parameters, but the user experience is poor and the professional requirement is high
Solution Approach 1:
The patent uses a 3D human body model as a copy of the user's actual body. The system creates a digital replica by matching the user's photo profile with the 3D model profile, then extracts figure parameters from this copy. This eliminates the need for users to manually measure themselves while maintaining high accuracy through automated profile matching and model adjustment.
2Measurement precision
If high-tech instruments and equipment are used for measurement, then accurate figure parameters can be acquired, but the cost is high and the equipment cannot be owned by individual users
Solution Approach 1:
The patent replaces complex mechanical measurement instruments (infrared scanners, radar equipment) with a software-based photo processing system. Instead of using expensive physical devices to scan and measure the user's body, the system uses image processing algorithms to analyze a regular photo, extract the profile, and match it with a 3D model. This substitution dramatically reduces device complexity and cost while maintaining measurement accuracy.
3Measurement precision
If high-tech scanning equipment is used, then figure parameters can be acquired accurately, but the user needs to go to special locations and the time cost is high
Solution Approach 1:
The patent performs preliminary actions by pre-building a parameterized 3D human body model with adjustable parameters before the actual measurement process. When a user takes a photo, the system can quickly match the profile against the pre-prepared model and extract parameters without requiring complex real-time scanning or processing. This preliminary preparation enables fast, accurate measurements that users can perform at any time without visiting special locations.

AI summary
The present disclosure discloses a method and a device for acquiring figure parameters of a user. The method includes the following steps: acquiring a photo of the user; processing the photo to generate a profile of the user; taking a parameterized three-dimensional human body model with a projection profile consistent with the profile of the user as a target parameterized three-dimensional human body model; and taking figure parameters of the target parameterized three-dimensional human body model as figure parameters of the user.
