Introduction
Standard Technical Background
This standard, as the 261st part of the GA/T 2000 series, is the basic standard for the construction of public security informatization. With the popularization of intelligent video analysis system in the security field, standardized coding of upper body clothing features has become a key technical support for improving personnel recognition efficiency.
Coding System Analysis
| Code Type | Code Length | Capacity Range | Extensibility |
|---|---|---|---|
| Sequence Code | 2 digits | 01-99 | 98/99 Special Code Reserved |
| Example: 05 | Sweater | Applicable to Face Recognition System Clothing Attribute Labeling | |
Core Code Table Detailed Explanation
Typical Application Scenario: In the class=instrument>video structured platform, by calling the 07 (standard clothing) code, rapid screening of staff in key places can be achieved, and the false alarm rate is reduced by 42%.
Special code description: 98 (no top) and 99 (other) are reserved for abnormal situations and need to be combined with the behavior analysis algorithm for comprehensive judgment.
Recommendations for the implementation of the standard
- Use with GA/T 2000.260 (lower body feature code) to form a complete clothing description
- In the intelligent security system, it is recommended to adopt a dual-field storage solution of code + confidence
- Special category sample libraries such as ethnic clothing (02) and protective clothing (14) need to be updated regularly
Technology evolution direction
With the diversification of clothing styles, future versions should consider:
- Add emerging categories such as Hanfu and cosplay clothing
- Introduce a multi-layer coding structure to distinguish styles/colors/patterns
- Establish a mapping relationship with the output results of the AI clothing recognition model
