Background Technology
[0002] Existing virtual fitting devices mostly rely on optical image acquisition, posing a risk of privacy leaks, and cannot penetrate clothing to obtain real body shape data, making it difficult to achieve accurate virtual fitting results. Traditional smart mirrors only have basic mirror reflection and simple display functions, lacking contactless 3D body modeling capabilities, failing to meet users' core need for accurate fitting. Furthermore, existing devices fail to integrate on-mirror touch operation, wireless projection, e-commerce interaction, and facial and body health monitoring, resulting in fragmented functions and a poor user experience. In addition, the local and cloud synchronization mechanisms for human 3D model data, virtual fitting records, and user health status data are incomplete, hindering consistent data management across multiple terminals and scenarios. Currently, the market lacks a complete smart mirror system that integrates radar-based non-contact 3D modeling and e-commerce virtual fitting, along with data synchronization, health monitoring, wireless projection, and reverse touch control. Summary of the Invention
[0003] 1. Technical problems to be solved:
[0004] To address the shortcomings of existing technologies, this invention aims to provide a smart mirror with projection capabilities based on radar 3D modeling, along with an e-commerce virtual try-on and data synchronization system. This solves the privacy risks and inaccurate body measurement issues caused by existing virtual try-on devices relying on optical data acquisition. It also addresses the technical deficiencies of traditional smart mirrors, such as lack of 3D modeling capabilities and fragmented functions. Furthermore, it resolves the problems of imperfect data synchronization mechanisms, high hardware costs, and difficulties in mass production associated with related devices. This invention achieves accurate body modeling through clothing using non-contact radar technology. It employs a separate design for radar modeling and camera recognition modules, mitigating privacy risks from the outset. It integrates wireless projection, reverse touch control, virtual try-on, health monitoring, and data synchronization into a unified system, creating a closed-loop process from body measurement to e-commerce ordering. Simultaneously, it utilizes a lightweight hardware design, delegating complex calculations to an external smart terminal, reducing hardware costs and adapting to various home and commercial scenarios. This effectively addresses the shortcomings of existing integrated smart mirror systems on the market.
[0005] 2. Technical Solution:
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a smart mirror with projection capability based on radar 3D modeling and an e-commerce virtual try-on and data synchronization system, including a smart mirror body, a semi-transparent mirror touch display module, a radar 3D body measurement module, a camera module, a wireless projection and reverse touch module, an identity recognition and status monitoring module, a data synchronization module, and a main control module. The main control module is the core control center of the system. All functional modules work together to realize the integrated functions of non-contact body measurement, virtual try-on, mirror operation, status monitoring, and data synchronization.
[0007] The main control module is a low-power embedded control unit that does not perform complex calculations. It is only responsible for connecting, driving, and transmitting basic instructions to various hardware modules, completing data transfer between modules, device start / stop management, and simple logic control. It is adapted to the lightweight hardware design of the system and effectively reduces hardware costs.
[0008] The radar 3D body shape measurement module adopts non-contact radar sensing technology, with low operating power and electromagnetic radiation levels lower than those of everyday consumer electronic devices such as Wi-Fi and mobile phones, making it safe and harmless to the human body. It can penetrate clothing to obtain the 3D contour information of the entire human body without contact, independently complete the measurement of the dimensions of multiple parts of the human body and the reconstruction of 3D digital models, and does not rely on cameras for body shape modeling, providing accurate basic data of human body shape for virtual try-on.
[0009] The camera module is dedicated to face recognition, facial feature acquisition, facial state analysis, and body health recording. It does not participate in 3D body modeling and works independently from the radar 3D body measurement module. This ensures the realization of identity recognition and state monitoring functions while avoiding the privacy leakage risks associated with optical image acquisition.
[0010] The semi-transparent mirror touch display module combines mirror reflection, high-definition display output, and capacitive touch functions. While displaying the operation interface and virtual try-on effect, it maintains the mirror reflection function, so that the human body image and the displayed content are presented synchronously. Users can directly complete various touch operations on the mirror surface.
[0011] The wireless projection and reverse touch control module supports a universal wireless projection protocol, enabling stable wireless connection with external smart terminals and one-click projection of the screen. It can also synchronously map the touch operation of the mirror to the external terminal for control, allowing users to complete the entire e-commerce process, such as browsing products, triggering virtual try-on, and submitting orders, on the mirror.
[0012] The identity recognition and status monitoring module automatically identifies the user's identity through the camera, retrieves the user's historical body shape, clothing fitting, facial and body posture data, realizes the comparison and analysis of the current facial, body posture and skin condition with historical data, completes the tracking of body posture changes and health data recording, and forms a long-term user status monitoring system.
[0013] The data synchronization module enables automatic synchronization of human 3D model data, virtual try-on records, and user facial and body posture data between local devices, the cloud, and e-commerce servers. This ensures data consistency across multiple terminals and scenarios, facilitating cross-device viewing and use. The system's core functions are radar 3D body modeling and e-commerce virtual try-on. Modules work collaboratively to achieve a fully integrated process, from non-contact body measurement and 3D model reconstruction to virtual try-on on a mirror, e-commerce ordering, identity recognition, status monitoring, and data synchronization. Furthermore, a lightweight hardware architecture significantly reduces hardware costs and structural complexity.

It realizes a complete technical closed loop from human body modeling to virtual try-on, e-commerce ordering, and then to status monitoring and data synchronization. It solves the defects of existing equipment in terms of scattered functions and poor user experience. The user process is smooth and the functions are complete, providing users with a one-stop user experience.
[0019] (5) The main body of the smart mirror of the present invention supports multiple installation and placement methods, and can be adapted to family daily dressing and body health monitoring scenarios, as well as commercial virtual fitting and merchandise sales scenarios such as clothing stores and shopping malls. It takes into account both personal use and commercial operation, and is highly practical.
[0020] (6) The radar three-dimensional body shape measurement module used in this invention has low operating power and electromagnetic radiation level lower than that of everyday electronic devices such as mobile phones and wireless routers. It is highly safe to use and can reduce users' concerns about radiation from close-range electronic devices.
[0021] (7) The present invention sets up an independent data synchronization module to realize the automatic synchronization of human body three-dimensional model, fitting records, user status data in local, cloud and e-commerce server, ensure data consistency of multiple terminals and multiple scenarios, solve the technical problem of imperfect data synchronization mechanism of existing related devices, facilitate users to retrieve and use their own data across devices and scenarios, and improve the flexibility and ease of use of the system.
[0022] Low-cost implementation This system can be implemented using a lightweight hardware structure: the main body of the smart mirror only includes a semi-transparent touch display panel, a radar 3D body measurement module, a camera module, and a simplified main control unit, requiring no independent operating system or... With a dedicated internet access module, all data processing, interface rendering, e-commerce interaction, and complex calculations can be completed by external smart terminals (mobile phones, tablets, etc.), significantly reducing hardware requirements while achieving all core functions. The low cost and structural complexity facilitate mass production and market penetration. Attached Figure Description
