Handheld Gimbal Target Tracking for Stable Moving-Object Video
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld gimbals struggle to maintain video stability when recording moving targets, as they often fail to follow the target's speed, leading to compromised video quality due to delayed or inappropriate motion control.
Innovation Solution
A handheld gimbal system equipped with a human-machine interface component, including a display screen and processor, that automatically recognizes the target object and adjusts the gimbal's motion to match the target's movement, ensuring synchronized and stable video recording by controlling the gimbal's rotation speed and acceleration based on the target's motion status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the gimbal follows the target object's motion, then video quality is improved, but the gimbal cannot keep up with fast-moving targets, causing tracking failure
Solution Approach 1:
The gimbal system dynamically adjusts its motion parameters based on the target object's movement characteristics. The control system continuously monitors the target's speed and acceleration, then adapts the gimbal's following motion in real-time, allowing it to transition between static and dynamic tracking modes to maintain reliable video quality across varying target speeds
Solution Approach 2:
The system changes operational parameters including rotation speed, acceleration, and following distance based on the detected target motion status. When the target moves faster, the gimbal increases its rotation speed and adjusts acceleration parameters to maintain tracking, directly addressing the speed limitation that causes tracking failure
2Speed
If the gimbal rotates quickly to follow the target, then tracking capability is improved, but video stability deteriorates due to excessive rotation speed
Solution Approach 1:
The gimbal employs dynamic motion control that adjusts rotation speed based on real-time target distance and motion status. When the target is far away, the gimbal rotates more quickly to maintain tracking. When the target is close or moving slowly, the rotation speed automatically reduces, preventing excessive motion that would compromise video stability
Solution Approach 2:
The control system continuously receives feedback about target position, distance, and motion status, then adjusts the gimbal's rotation speed accordingly. This closed-loop control ensures the gimbal rotates quickly enough to track the target while automatically reducing speed when appropriate to maintain video stability
3Ease of operation
If the gimbal uses automatic target recognition, then ease of operation is improved, but device complexity increases due to additional processing requirements
Solution Approach 1:
The gimbal system performs automatic target recognition and tracking without requiring manual user input. The processor automatically detects the target object, determines its motion status, and controls the gimbal's following motion, making the system self-sufficient and easy to operate while the processing complexity is managed through efficient algorithms
