Predictive Camera Activation for Movement Track Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitor systems face hysteresis in confirming the movement tracks of preset individuals, leading to potential security risks due to the absence of a previous track record, which hinders accurate tracking and increases security risks in monitored areas.
Innovation Solution
A method and device that predict the movement track of a preset person based on the current geographic location and motion state, activating target camera devices along the track to ensure timely and accurate tracking and recording of the person's movement, thereby avoiding the limitations of previous systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing monitor systems are used for simple shooting and invocation in later stage, then device complexity is reduced and ease of operation is improved, but tracking accuracy deteriorates and loss of information increases due to absence of previous track records
Solution Approach 1:
The system performs preliminary actions by predicting the movement track of the preset person based on current geographic location and motion state before actual tracking is needed. This allows the system to proactively activate camera devices along the predicted path, ensuring continuous tracking coverage and eliminating the need for reactive invocation, thereby resolving the contradiction between ease of operation and tracking accuracy
Solution Approach 2:
The system implements feedback by continuously monitoring the preset person's motion state and comparing it with the predicted track. When deviations are detected or when the person enters new areas, the system adjusts camera activation decisions accordingly. This closed-loop feedback mechanism ensures accurate tracking while maintaining operational simplicity through automated decision-making
2Use of energy by moving object
If existing monitor systems merely capture images for later invocation, then use of energy is reduced and device complexity is minimized, but reliability deteriorates and loss of time increases due to hysteresis in confirming movement tracks
Solution Approach 1:
The system dynamically adjusts camera device activation based on real-time conditions. Instead of continuously activating all cameras or relying on manual invocation, the system activates only the necessary camera devices along the predicted movement track. This dynamic adaptation allows the system to maintain reliable tracking while minimizing energy consumption, resolving the contradiction between reliability and energy use
Solution Approach 2:
By predicting the movement track in advance and pre-activating camera devices along the predicted path, the system eliminates hysteresis delays. The cameras are already ready to capture when the preset person arrives, ensuring reliable tracking without the time loss associated with reactive system activation, while still maintaining energy efficiency through selective activation
