Automatic Tracking Camera Dynamic Capture Position Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional automatic tracking camera systems require a preset position for the object to be tracked, leading to inconvenience when the object's actual position differs, as they struggle to initiate tracking without significant image changes and cannot start tracking until the object reaches the predetermined position.
Innovation Solution
An automatic tracking camera system that includes an image pickup unit, a rotating unit, a tracking object detector, a motion vector detector, and a controller capable of switching between capture and maintenance modes, allowing the camera to adjust its position to track the object at a predetermined position on the screen while minimizing image changes by controlling the rotation direction and speed based on the object's motion vector.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the camera is rotated to display the object at the preset tracking position immediately when detection occurs, then the object can be tracked at the predetermined position, but a significant change occurs in the picked up image causing discomfort
Solution Approach 1:
The patent applies dynamics by making the capture position adjustable between a fixed preset position and a dynamic position based on the object's current location. The capture position setting unit dynamically determines the optimal position by considering the object's detected position and motion vector, allowing the system to adapt between maintaining precise tracking positioning and minimizing image changes for viewer comfort.
2Ease of operation
If the camera waits for the object to reach the preset position before starting tracking, then significant image changes are avoided, but automatic tracking cannot be started when the object has not passed through the predetermined set position
Solution Approach 1:
The patent applies preliminary action by pre-calculating and setting the capture position based on the object's current position and motion vector before tracking begins. The capture position setting unit performs preliminary determination of the optimal capture position, enabling the system to start tracking immediately without waiting for the object to reach a preset position, thus resolving the contradiction between viewing comfort and tracking start capability.
3Measurement precision
If the capture position is fixed at a preset position, then tracking position accuracy is maintained, but the system cannot adapt when the object's position differs from the preset position
Solution Approach 1:
The patent applies dynamics by making the capture position adjustable between a fixed preset position and a dynamic position based on the object's current location. The capture position setting unit dynamically determines the optimal position by considering the object's detected position and motion vector, allowing the system to adapt between maintaining precise tracking positioning and minimizing image changes for viewer comfort.
Solution Approach 2:
The patent applies parameter changes by modifying the capture position parameter based on the object's detected position and motion vector. The system changes the capture position from a fixed preset value to a dynamically calculated value that optimizes both tracking accuracy and viewing comfort, demonstrating parameter adaptation to resolve the contradiction between position accuracy and adaptability.

AI summary
An automatic tracking camera system includes: a rotating unit for panning and tilting an image pickup unit including a lens apparatus and an image pickup apparatus; a tracking object detector; a motion vector detector for detecting a motion vector of the object to be tracked; a capture position setting unit for setting a capture position of the object to be tracked in the picked up image; and a controller for controlling drive of the rotating unit. The controller controls the rotating unit in a capture mode to capture the object to be tracked at the capture position based on the motion vector detected by the motion vector detector after the tracking object detector has detected the object to be tracked in the picked up image, and a maintenance mode to continuously capture the object to be tracked at the capture position after the capture mode.
