3D Truss Positioning for Suspected Articles in Air Cargo
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing air cargo security inspection systems struggle to accurately locate suspected articles within large pallets or containers, necessitating manual and repetitive unpacking inspections due to the difficulty in determining the precise position of the articles using imaging alone.
Innovation Solution
A system and method utilizing a truss indicating mechanism with a coordinate system and a ranging indicating device, such as a laser ranging indicator, to precisely locate suspected articles by defining and moving within a three-dimensional coordinate system, enabling accurate positioning and reducing the need for manual unpacking inspections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a comprehensive re-security inspection is performed for all cargoes on the pallet, then the suspected article can be found, but the inspection time and manpower are significantly increased
Solution Approach 1:
The patent applies preliminary action by performing a comprehensive security inspection of the entire pallet beforehand to identify suspected articles and their positions. The imaging apparatus captures images of all cargoes, and the processor pre-analyzes them to locate suspected articles. This preliminary detection eliminates the need for comprehensive re-inspection, as security personnel can directly proceed to unpack only the identified suspected cargoes, significantly reducing inspection time while maintaining detection accuracy.
2Reliability
If manual inspection is performed by security personnel, then the suspected article can be confirmed, but the operation complexity and time consumption increase
Solution Approach 1:
The patent applies feedback by providing the imaging apparatus with imaging information of the suspected article's position obtained from the comprehensive security inspection. The processor generates specific position information (such as coordinates or location identifiers) and feeds this back to security personnel. This feedback mechanism guides personnel directly to the suspected cargo location, simplifying their operation from searching the entire pallet to confirming only the identified suspect, thereby reducing operation complexity while maintaining confirmation accuracy.
3Device complexity
If only imaging from the security inspection apparatus is used, then the inspection process is simple, but the position determination of the suspected article becomes difficult
Solution Approach 1:
The patent applies the intermediary principle by introducing a processor as a mediator between the imaging apparatus and security personnel. The processor receives imaging information from the security inspection apparatus, analyzes the images to determine the precise position of suspected articles, and generates position information. This intermediary processing step enhances position determination accuracy without significantly increasing overall system complexity, as the processor automatically performs the analysis that would otherwise require complex manual interpretation of images.
