Camera Tracking Control Apparatus Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic tracking camera systems cannot arbitrarily change the position of an object within the image frame during tracking, limiting operator flexibility in adjusting the object's display location.
Innovation Solution
An automatic tracking control apparatus with an object recognition unit, tracking object setting unit, output position setting unit, control computing unit, and image output unit that allows operators to change the object's position in the image frame by suspending tracking, updating the output position, and restarting tracking to the new position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic tracking is enabled to keep the object at the center of the image, then the object is consistently displayed at the center position, but the position at which the object is output cannot be changed arbitrarily during tracking
Solution Approach 1:
The system dynamically switches between two tracking modes: automatic tracking that keeps the object at the center, and manual tracking that allows arbitrary position adjustment. This dynamic mode switching enables the system to adapt between stability and flexibility requirements during operation
Solution Approach 2:
The system performs preliminary actions by automatically moving the object to the desired output position before switching to manual tracking mode. This ensures the object is properly positioned before the operator takes over for fine-adjustment or arbitrary positioning
2Adaptability or versatility
If the template is replaced to track a new object during tracking, then the tracking object can be changed, but the object cannot be shifted to a desired position in the image
Solution Approach 1:
The system merges two separate functions into a unified workflow: object replacement (template replacement) and position adjustment. By combining these functions and enabling both through the same manual tracking mode, the system allows operators to both change tracking objects and adjust their positions arbitrarily
3Measurement precision
If the camera platform is controlled to keep the object at the center of the monitor, then consistent centering is achieved, but operator control for positioning the object at specific regions (leftmost, rightmost, etc.) is lost
Solution Approach 1:
The system dynamically transitions between automatic centering control and manual operator control. During automatic tracking, precise centering is maintained; when manual tracking mode is activated, full operator control for positioning objects at specific regions is restored

AI summary
An automatic tracking control apparatus for a camera apparatus having a panning or tilting function, comprising an object recognition unit to recognize an object in picked-up image, a tracking object setting unit to set the recognized object as tracking object, an output position setting unit to set a position in the image for outputting the image of the tracking object, a control computing unit to output drive signal to locate the tracked object at the output position, and an image output unit to output an image in which an indication of the tracking object is superimposed on the image. Automatic tracking is suspended to change the position of the tracking object in the image by the output position setting unit, and automatic tracking is restarted by outputting a drive signal for driving the camera apparatus to locate the tracked object at the output position.
