Security Inspection Label with Visual Identifier for Package Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In complex security inspection environments, such as civil aviation and subway sites, it is difficult to accurately match security inspection images of packages with their corresponding items due to overlapping images and differences in imaging mechanisms between visible light and security inspection systems, making it challenging to identify individual packages.
Innovation Solution
A label with a unique identifier, comprising positioning points and characters, is bound to items undergoing security inspection, allowing the identifier to be displayed in the security inspection image. The security inspection device recognizes the identifier in the image and compares it with the label's identifier to track and identify individual items, even in complex environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple packages with RFID labels enter the security inspection machine at the same time, then the security inspection process can handle multiple items efficiently, but it becomes difficult to match between the security inspection images of the packages and the packages one by one
Solution Approach 1:
The system divides the identification process into two parts: RFID labels provide initial package identification while visual identifiers (patterns, colors, shapes) on the packages provide image-based verification. This segmentation allows the system to handle multiple packages simultaneously by matching both RFID data and visual image data, resolving the contradiction between high throughput and accurate matching.
2Reliability
If a RFID label is attached to a package for identification, then the package can be identified in the coverage area of the RFID identification system, but if multiple packages enter simultaneously, individual matching between images and packages remains difficult
Solution Approach 1:
The system merges RFID identification technology with visual image recognition technology. RFID labels provide reliable package identification while visual identifiers (patterns, colors, shapes) on the packages enable image-based verification. By combining these two identification methods, the system achieves accurate individual package matching without increasing device complexity, as the visual identifiers are naturally present on packages.
3Ease of manufacture
If visible light imaging is used to capture package images, then the imaging process is simple and direct, but the imaging mechanism differs greatly from security inspection machines making package distinction difficult
Solution Approach 1:
Visual identifiers (patterns, colors, shapes) serve as an intermediary between the simple visible light imaging system and the security inspection machine's imaging system. These identifiers are designed to be clearly visible in both visible light and security inspection images, bridging the gap between the two different imaging mechanisms and enabling accurate package distinction despite the imaging differences.

AI summary
Disclosed are a label and a method for positioning an item subjected to security inspection. Same are used in the technical field of security inspection and can solve the problem that security inspection information cannot be associated with positional information about the item subjected to security inspection in a complex environment. The method includes: binding an item subjected to security inspection with a label including an identifier (201); obtaining a security inspection image of the item subjected to security inspection when passing through a security inspection device (202); recognizing an identifier in the security inspection image (203); and comparing and tracking the identifier recognized from the security inspection image with the identifier in the label bound with the item subjected to security inspection when the item subjected to security inspection needs to be positioned (204).
