Pedestrian Tracking for Security Inspection Information Binding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current face recognition-based security inspection methods are inefficient due to reduced accuracy when faces are blocked or angled, leading to incomplete passenger-baggage binding and decreased security inspection speed, especially in high-traffic areas, and fail to integrate passenger identity information effectively.
Innovation Solution
A method and device that acquire video streams, detect pedestrian frames with coordinate and tracking information, extract pedestrian features, verify identities, and bind security inspection information, including baggage and passenger data, using a combination of cameras and detection apparatuses to ensure comprehensive and efficient information binding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If face recognition method is used to bind passenger with baggage, then passenger-baggage binding can be achieved, but recognition accuracy deteriorates when face is blocked or angled
Solution Approach 1:
The patent introduces tracking information as an intermediary element that connects pedestrian detection with identity verification. Instead of directly relying on face recognition, the system uses tracking IDs to associate pedestrians with their identities and baggage, thereby bypassing the limitations of face recognition accuracy when faces are blocked or angled.
Solution Approach 2:
The patent replaces the mechanical face recognition system with a tracking-based identification system. By substituting direct facial feature matching with continuous tracking and association of tracking information, the system maintains reliability even when face recognition fails due to masking or improper angles.
2Device complexity
If only passenger-baggage binding is achieved, then binding process is simple, but security inspection information completeness deteriorates
Solution Approach 1:
The patent merges multiple binding operations into a unified process. It combines passenger-baggage binding, passenger identity binding, and security inspection information binding into a single integrated system that uses tracking information as the common thread, thereby maintaining simplicity while achieving completeness.
Solution Approach 2:
The tracking information serves multiple functions simultaneously: it identifies the pedestrian, associates baggage with the passenger, and links security inspection results. This multi-functional approach eliminates the need for separate binding processes while ensuring all security information is captured.
3Productivity
If face-based binding method is used, then binding can be performed quickly, but security inspection speed deteriorates when recognition accuracy is low
Solution Approach 1:
The system performs preliminary tracking and association of tracking information before the actual security inspection. By pre-establishing the connection between pedestrian, baggage, and identity through tracking IDs, the system avoids re-attempts during inspection, thereby maintaining high speed even when face recognition fails.

AI summary
Provided are a method and a device of binding security inspection information, an electronic apparatus and a storage medium, which may be applied to the field of security inspection technology. In the method of binding security inspection information of the present disclosure, the pedestrian detection frame is acquired by detecting the video stream, and each pedestrian detection frame has the coordinate information and the tracking information. According to the coordinate information and the tracking information of the pedestrian detection frame, the baggage security inspection information, the pedestrian security inspection information, and the identity information are bound to acquire all security inspection information of a detected person, so that a security inspection efficiency is improved.
