Introduction

Interpretation of the core content of the standard

As the basic specification for intelligent analysis of video image information, this standard defines 5 typical types of area trigger behaviors:

Code	Behavior type	Technical characteristics	Typical scenarios
1	Entering the area	Target crossing the virtual perimeter	Key area protection
2	Leaving the area	Motion trajectory analysis	Personnel control
5	Continuous presence in the area	Residence time judgment	Suspicious object detection

Technology evolution analysis

This standard reflects the three development stages of video analysis technology:

Basic perception stage (codes 1-2): Boundary triggering based on motion target detection
Scene understanding stage (codes 3-4): Disappearance/appearance judgment combined with background modeling
Behavior analysis stage (code 5): Continuous status monitoring with the introduction of time dimension

Practical application case

In smart checkpoint system, license plate recognition is triggered by code 1 (entering the area), and combined with code 5 (remaining in the area) to achieve abnormal stay warning. A pilot project has improved the control efficiency by 40%

Implementation suggestions

It is recommended to reserve an expansion interface for code 9 (others) during system integration
For use with GA/T 2000.151 "Target Classification Code"
Code conversion needs to be implemented in conjunction with GB/T 28181 standard
