Direct answer
This requirement cannot be completed by person detection and a simple zone rule alone. Off-zone unloading requires both a non-compliant vehicle position and confirmed unloading activity. Pickup authorization requires identity plus a valid task, zone and time window. Cargo carry-out requires a persistent person-cargo relationship followed by an outward crossing of the controlled boundary.
Off-zone vehicle unloading
The vehicle reference point is outside the permitted area and cargo movement, manual handling or unloading-equipment activity has been confirmed. Incorrect parking alone triggers guidance, not a formal unloading event.
Unauthorized pickup
A person handles cargo while being unregistered, outside the permitted task, area or time window, mismatched to the work order, or temporarily unidentifiable.
Cargo carry-out
A stable person-cargo association persists while the person moves from inside to outside the formal boundary. Ground-plane foot position is preferred for crossing logic.
Why relationships and state are required
Single-frame detection can show that a vehicle, person or cargo item is present, but cannot reliably determine unloading activity, ownership of a carried item or the difference between temporary occlusion and a true exit. The event engine therefore maintains vehicle, person, cargo, identity and authorization state over time and separates early warnings, formal alarms and identity-unconfirmed events.
Identity and authorization
Authorization should combine identity, current task, zone and time. The state model should distinguish authorized, recognized but unauthorized, unregistered, identity unconfirmed and temporary exceptions. Higher-value cargo can combine face capture with staff badges, access cards, QR codes or WMS work orders. A distant overhead camera should not be assigned mandatory face matching.
Fit and limitations
- Suitable for fixed loading docks, warehouse bays, factory receiving points and logistics handover zones with definable boundaries and stable workflows.
- Required inputs include camera and lens parameters, day and night video, vehicle types, unloading methods, cargo forms, authorization source, integration interfaces and acceptance rules.
- Strong backlight, persistent occlusion, dense crossing traffic, bulk or deformable cargo, moving unloading zones and sites without a viable identity-capture path require separate assessment.
- The system can provide anomaly evidence and alerts; final operational action remains subject to site policy.
