Description

Technical Field

[0002] This invention relates to the fields of indoor 3D radar perception, object tracking, access control, contactless authorization and trajectory storage technology, specifically an indoor intelligent management system based on full-domain radar perception, featuring a dual-layer point cloud data architecture, strong object binding reasoning, whitelist hierarchical authorization and general signal output. Background Technology

[0004] Existing indoor multi-radar fusion sensing solutions have achieved basic sensing functions such as full-area coverage, unified coordinate system, central host data fusion, and continuous human ID tracking, all of which fall within the scope of existing technologies. However, existing technologies have the following shortcomings: they only achieve tracking when the human body is visible, lacking a strong object binding inference mechanism in scenarios involving occlusion, overlapping, or close contact; they lack independent object ID allocation and full-area object search and monitoring capabilities; they lack a dual-layer point cloud data local deployment architecture; they lack whitelist-based hierarchical permissions, time-limited and area-limited authorization, absolute control areas, and seamless, cardless access mechanisms; and they do not support an ecosystem-compatible mode that only outputs general standardized signals and does not directly control devices. Therefore, existing technologies cannot simultaneously meet the needs of access management, object monitoring, privacy security, and trajectory recording in multiple scenarios such as homes, offices, and shopping malls. Summary of the Invention

[0006] This invention aims to provide an indoor full-domain radar matrix authorized tracking system, which achieves basic perception based on the existing full-domain radar networking, unified coordinate system and central data fusion architecture. Its core innovation lies in: 1. Two-layer point cloud data architecture The system deploys two independent point cloud layers locally. The two layers run data synchronously, are physically isolated, and neither is uploaded externally. • Low-level point cloud: Used only by the system itself for calls, calculations and logical judgments. It is not displayed to the outside world or open to users. It is used to accurately identify coordinates, overlapping relationships, occlusion states and behavior reasoning. • Surface point cloud: Used for visualization, allowing users to view, manage, and operate it. The interface is user-friendly, intuitive, and readable.

[0007] The two-layer point cloud is completely stored and computed locally, achieving a secure isolation mode where "the system uses the lower layer and people view the upper layer".

[0008] 2. Item unique ID + strong binding reasoning based on occlusion / overlay / close contact The system assigns a unique item ID to each monitored item, forming a dual ID system with the person's ID. When an item is obscured, shielded by metal, carried close to the body, or overlapped with other objects, making it impossible to directly identify, the system uses the coordinate overlap ratio, spatial overlap, and positional continuity of the underlying point cloud to perform logical reasoning and automatically establish a strong binding association with the corresponding target, ensuring that the item ID is not lost, changed, or confused. When the obscuration is removed, the item is released from the hand, or the location is separated, the system automatically unbinds and resumes direct tracking, achieving continuous monitoring of all items in all states across the entire domain.

[0009] 3. Whitelist with the highest level of authority and multi-level hierarchical authorization The whitelist is the highest-level authority in the system, allowing for customized allocation of time-limited permissions, access permissions to designated areas, access control permissions, and device signal trigger permissions for authorized individuals. It supports multiple scenarios including homes, offices, and shopping malls: for example, granting minors access to designated areas and access control permissions while retaining trajectory monitoring capabilities; assigning area permissions to office workers and shopping mall staff based on their roles; and supporting the setting of absolutely controlled areas, where only the whitelisted individuals can trigger behavioral intent signals, and other personnel cannot trigger them even if authorized.

[0010] 4. Universal standardized signal output The system performs lightweight calculations through behavioral logic packages. After determining the user's behavioral intent, it only outputs industry-standard signals without binding to transmission protocols, transmission media, or gateways. Smart home device modules autonomously decide whether to receive, respond, or perform on / off actions. The system does not directly control the devices, does not intrude into the manufacturer's ecosystem, does not exceed its authority, and is compatible with all smart device manufacturers.

[0011] 5. Global trajectory storage and authorization log The system locally records the movement trajectories of people and objects, authorization records, and permission usage records across the entire domain, forming a complete evidence log; a whitelist allows for tiered access to view trajectories, enabling traceable, monitorable, and auditable full-domain management.

[0012] 6. Emergency mechanical encryption structure without electricity The system is equipped with a local, independent, non-electric mechanical password backup structure. This structure is forcibly locked during normal system operation and is automatically unlocked only in the event of power failure, malfunction, or host failure, for extreme emergency door opening, ensuring both security and privacy protection. Detailed Implementation

[0014] The present invention will be further described below with reference to specific embodiments.

[0015] 5.1 System Deployment Multiple radars are deployed throughout the indoor area, connected to a central host to achieve unified coordinates and data fusion. All data is processed and stored locally, with no external data being forcibly uploaded, ensuring data security and controllable privacy.

[0016] 5.2 Two-layer point cloud operation The system operates on a two-layer point cloud architecture. The lower-layer point cloud is used for system logic calculations and coordinate recognition and is not publicly accessible; the upper-layer point cloud is transformed and used for user visualization. The two layers of point clouds are physically isolated and run synchronously to achieve secure isolation.

[0017] 5.3 Item Tracking and Strong Binding After a user binds an item's ID, the system tracks it directly under normal conditions. When an item is obscured, overlapped, or carried close to the body, making direct identification impossible, the system uses logical deduction based on the coordinate overlap ratio, spatial overlap, and positional continuity of the underlying point cloud to automatically establish a strong binding with the nearest target, keeping the item ID unchanged. Once the obscuration is removed or the item is separated, the system automatically unbinds and resumes direct tracking.

[0018] 5.4 Whitelist Permission Configuration The whitelist, acting as the highest-level authority, can be configured with tiered authorization, time-limited permissions, regional permissions, and absolute control zones. In home settings, it can grant access to designated areas for minors while retaining their activity tracking; in office and shopping mall settings, it can assign area access and door opening permissions based on roles.

[0019] 5.5 Signal Output and Device Response The system performs lightweight calculations using a built-in behavior logic package. After determining the user's behavioral intent, it outputs only a general, standardized signal. This signal is not bound to a transmission protocol or medium; the smart device autonomously decides whether to receive and execute it, and the system does not perform direct device control.

[0020] 5.6 Global Tracking The system locally records the movement trajectories of people and objects, authorization records, and permission usage records across the entire domain, forming a complete evidence log. A whitelist allows for tiered access to view these trajectories, enabling traceable, monitorable, and auditable full-domain management.

[0021] 5.7 Emergency Response Mechanism The emergency mechanical password module is forcibly locked during normal system operation; it is only automatically unlocked in the event of power failure, malfunction, or host failure, allowing users to open the door in an emergency, ensuring both security and privacy protection.
