Camera Controller Automatic Tracking Transfer Path
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera control systems require manual user intervention to switch between cameras when a moving object leaves the field of view, which can result in the object being lost, especially when it moves quickly or unpredictably.
Innovation Solution
A camera control apparatus that converts image center coordinates from a main camera to three-dimensional coordinates using camera installation information, selects a new main camera from sub-cameras based on field-of-view information, and calculates control values to transfer the gaze to the new camera, ensuring continuous tracking of the object.

Engineering Contradiction Analysis
1Reliability
If manual camera switching is used when an object leaves the field of view, then the user can select another camera to track the object, but the object may be lost during the selection process, especially when the object moves fast or unpredictably
Solution Approach 1:
The system pre-calculates and stores transfer paths between cameras in advance. When a camera needs to switch, the controller retrieves the pre-computed transfer path information, enabling rapid camera switching without real-time calculation delays. This preliminary preparation ensures the object is not lost during transitions.
Solution Approach 2:
The system continuously monitors the object's position and camera field of view, providing feedback to the controller. When the object approaches the boundary of the current camera's field of view, the controller proactively initiates the camera switching process using pre-calculated transfer paths, ensuring continuous tracking without loss of the object.
2Productivity
If the system automatically transfers camera duty along a calculated transfer path, then continuous tracking of moving objects is ensured without manual intervention, but the device complexity increases
Solution Approach 1:
The camera control system performs automatic camera switching based on object position and pre-calculated transfer paths. The system serves itself by autonomously determining when and how to switch cameras without requiring manual user intervention, thereby improving tracking efficiency while the automation complexity is managed through pre-computation.
Solution Approach 2:
Transfer paths between cameras are pre-calculated and stored in the controller before runtime. This preliminary computation of optimal camera transfer paths reduces real-time processing complexity while enabling efficient automatic camera switching for continuous object tracking.

AI summary
A camera control apparatus includes a database to store camera installation information of the cameras including a main camera and one or more sub-cameras; an image acquisition unit to acquire at least one image from the cameras; and a camera controller to convert image center coordinates of the image acquired by the main camera to three-dimensional coordinates on a three-dimensional reference coordinate system, by using the camera installation information, select at least one new main camera from among the one or more sub-cameras that include the three-dimensional coordinates as field-of-view information, and calculate a control value of the newly selected main camera for controlling the newly selected main camera to gaze the three-dimensional coordinates.
