Gimbal Auto-Centering Within a Cone-Limited Imaging Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gimbal cameras require manual and inefficient adjustments to orient the camera for optimal imaging, and lack waterproof accessories for underwater use, leading to inefficiencies and potential image quality issues.
Innovation Solution
A gimbal control method that automatically stabilizes and adjusts the imaging direction within a preset cone angle range using a gimbal controller, with optional waterproof housing for underwater use, ensuring the imaging field is not blocked and maintaining image quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation is used to retune the gimbal to the center, then the imaging direction can be adjusted, but the adjustment process is inefficient and time-consuming
Solution Approach 1:
The gimbal system performs self-adjustment through automatic centering functionality. The controller automatically calculates the offset between the current imaging direction and the desired direction, then drives the gimbal to rotate and stabilize at the correct position without requiring manual operation, making the system serve itself
Solution Approach 2:
The patent replaces manual mechanical adjustment with an automated control system. The controller uses electronic signals to drive the gimbal motors based on calculated offset values, substituting the mechanical hand-tuning process with an automated electromechanical system that computes and executes positioning automatically
2Extent of automation
If the gimbal orientation is manually adjusted, then the imaging direction can be changed, but the process lacks automation and requires user intervention
Solution Approach 1:
The gimbal system performs self-adjustment through automatic centering functionality. The controller automatically calculates the offset between the current imaging direction and the desired direction, then drives the gimbal to rotate and stabilize at the correct position without requiring manual operation, making the system serve itself
Solution Approach 2:
The system implements automatic feedback control by continuously monitoring the gimbal's imaging direction, calculating the offset from the desired position, and adjusting the gimbal orientation based on this feedback. This closed-loop control enables automated adaptation to different shooting scenarios
3Area of stationary object
If the imaging field of view exceeds the cone angle range, then more scene can be captured, but the image may be blocked or obstructed
Solution Approach 1:
The system applies partial action by limiting the gimbal's imaging field of view to a specific cone angle range. Rather than allowing full 360-degree rotation, the gimbal is constrained to rotate only within the necessary angular sector to capture the target, preventing the imaging field from exceeding boundaries where obstruction occurs

AI summary
A method for controlling a gimbal, implemented by a gimbal controller. The gimbal includes a gimbal assembly connected to the gimbal controller, the gimbal assembly being configured to mount an imaging device and drive the imaging device to rotate to adjust an imaging direction of the imaging device. The method includes determining whether the gimbal has entered a preset mode; and controlling rotation of the gimbal assembly to stabilize the imaging direction of the imaging device at a first balance direction when the gimbal enters the preset mode, and controlling a movement of the gimbal assembly such that the imaging direction of the imaging device is within a first cone angle range with the first balance direction as an axis before the gimbal exiting the preset mode.
