Body-Worn Camera Category Tagging to Cut Server-Based Video Sorting

Solution Overview

Problem

Police officers face significant time-consuming tasks when returning to the station to tag category names for numerous videos recorded during duty, as existing body-worn cameras require manual processing on a server.

Innovation Solution

A body-worn camera equipped with a central processing unit, video recording module, turntable, and main button, which executes a video tagging program to save the relationship between category names and videos upon user input, allowing immediate tagging during recording.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of time

If police officers manually tag video category names on a server after returning to the station, then video categorization can be completed, but a significant amount of time is consumed due to heavy workload

Engineering Contradiction:

Improvetime for tagging videosVSAvoidefficiency of police officers

Core Design Contradiction:

Loss of timeVSProductivity

Solution Approach 1:

The system performs video tagging action in advance by automatically executing the tagging program immediately after video recording is completed. The central processing unit automatically tags the just-recorded video with the current category name without waiting for the police officer to return to the station, thus completing the categorization task preliminarily and eliminating the need for subsequent manual tagging.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The body-worn camera system performs self-service by automatically tagging its own recorded videos. The central processing unit executes the tagging program using the current category name displayed on the display unit, enabling the system to categorize its own output without external human intervention, thereby saving police officers' time and improving productivity.

Inventive Principle:

Principle #25Self-service

2Ease of operation

If police officers tag multiple videos individually on a server, then each video can be categorized, but the process becomes very time-consuming with large numbers of videos

Engineering Contradiction:

Improvevideo tagging processVSAvoidtime for categorizing videos

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The body-worn camera system performs self-service by automatically tagging its own recorded videos. The central processing unit executes the tagging program using the current category name displayed on the display unit, enabling the system to categorize its own output without external human intervention, thereby saving police officers' time and improving productivity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs video tagging action in advance by automatically executing the tagging program immediately after video recording is completed. The central processing unit automatically tags the just-recorded video with the current category name without waiting for the police officer to return to the station, thus completing the categorization task preliminarily and eliminating the need for subsequent manual tagging.

Inventive Principle:

Principle #10Preliminary action

3Reliability

If manual video tagging is performed on a server after duty completion, then videos are categorized, but police officers spend excessive time on this administrative task

Engineering Contradiction:

Improvevideo categorization accuracyVSAvoidtime spent tagging videos

Core Design Contradiction:

ReliabilityVSLoss of time

AI summary

A body-worn camera and an operation method thereof are provided, and the body-worn camera a central processing unit (7), a video recording module (2), a turntable (3), and a main button (5). The video recording module (2) is electrically connected to the central processing unit (7). The turntable (3) is electrically connected to the central processing unit (7). The main button (5) is electrically connected to the central processing unit (7). After the video recording module (2) completes recording a video, when the central processing unit (7) receives a category mode signal from the turntable (3) and receives a category name confirmation signal from the main button (5), the central processing unit (7) executes a video tagging program, and the video tagging program saves a corresponding relationship between a category name and the video.
