Tracking Assistance Device Map-Based Camera Prediction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing monitoring systems face challenges in efficiently tracking a moving object across multiple cameras, leading to high burden on monitoring personnel and potential loss of sight due to incorrect camera predictions and errors in inter-camera tracing processes.
Innovation Solution
A tracking assistance device and method that displays a monitoring screen with multiple display views on a map image, featuring a target-to-be-tracked setting unit, prediction unit, and display view indicating unit to highlight the next display view where the target will appear, allowing for accurate tracking and correction of errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the camera that will next capture the image of the person being monitored is predicted based on direction of movement, then the burden of the monitoring person is reduced, but if there is another person in the captured image, the prediction may be based on the wrong person causing loss of sight
Solution Approach 1:
The system provides feedback by highlighting the predicted next display view, allowing the monitoring person to verify whether the predicted camera correctly captures the intended target. This feedback mechanism enables correction of prediction errors without increasing operational burden.
Solution Approach 2:
The system performs preliminary action by predicting and highlighting the next display view before the monitoring person needs to manually search for the target. This advance preparation reduces the time and effort required for tracking while maintaining accuracy through verification.
2Quantity of substance
If multiple display sections are arranged in the screen in correspondence with the number of cameras, then all captured images can be displayed, but it becomes difficult to determine the next display section promptly and exactly
Solution Approach 1:
The system applies local quality by providing special highlighting treatment to the predicted next display view, making it visually distinct from other display sections. This localized enhancement guides the monitoring person's attention to the most relevant section without requiring review of all sections.
Solution Approach 2:
The prediction unit acts as an intermediary between the multiple display sections and the monitoring person. It processes the spatial relationship information and camera prediction logic to identify and highlight the next relevant display view, simplifying the monitoring task.
3Productivity
If the tracing process uses inter-camera tracing to associate tracking information across cameras, then continuous tracking is enabled, but errors may occur causing inadvertent change of the person to be tracked
Solution Approach 1:
The system enables feedback verification of tracking accuracy by highlighting the predicted next display view where the target should appear. This allows the monitoring person to verify whether the inter-camera tracing correctly identified the same person across different cameras.
Solution Approach 2:
The prediction and highlighting mechanism provides a form of error cushioning by allowing the monitoring person to verify tracking accuracy before potential errors lead to loss of sight. The system prepares verification opportunities in advance through the prediction process.

AI summary
A tracking assistance device for assisting a monitoring person in tracking a moving object by displaying on a display device a monitoring screen in which display views for displaying in real time captured images taken by respective cameras are arranged on a map image representing a monitored area in accordance with an actual arrangement of the cameras, includes: a target-to-be-tracked setting unit that, in response to an input operation performed by the monitoring person on one of the display views to designate a moving object to be tracked, sets the designated moving object as a target to be tracked; a prediction unit that predicts a next display view in which the moving object set as the target to be tracked will appear next based on tracing information obtained by processing the captured images; and a display view indicating unit that indicates the next display view on the monitoring screen.
