Handheld Gimbal Fast-Follow Control for Rapid Target Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld gimbals struggle to quickly follow a target when the handle is rapidly rotated, leading to potential loss of the target during photography, especially in sudden movements.
Innovation Solution
A method and apparatus for controlling handheld gimbals that allow users to enter a fast following mode by updating control parameters such as maximum following rate and acceleration, and reducing the control dead zone, enabling the camera component to quickly track the handle's movement.

Engineering Contradiction Analysis
1Speed
If the common following mode is used, then the camera component can photograph video stably and smoothly, but the camera component cannot quickly follow a target when the handle is rapidly rotated
Solution Approach 1:
The patent implements a dynamic mode switching mechanism that allows the system to transition between common following mode and fast following mode based on operational needs. The fast following mode is activated when rapid target acquisition is required, dynamically adjusting control parameters including increasing maximum following rate and acceleration while reducing control dead zone, thereby resolving the contradiction between stable photography and quick target following.
Solution Approach 2:
The patent changes control parameters dynamically by switching between different operating modes. In fast following mode, the maximum following rate and acceleration parameters are increased, and the control dead zone is reduced compared to common following mode. These parameter changes enable the camera component to respond more quickly to handle rotations while maintaining reliability through mode-based parameter management.
2Speed
If the control dead zone is reduced to improve response sensitivity, then the camera component can respond faster to handle movement, but the control stability may be affected
Solution Approach 1:
The control dead zone parameter is dynamically adjusted based on the operating mode. In fast following mode, the control dead zone is reduced to improve response sensitivity and enable faster tracking of rapid handle movements. The system maintains control stability by confining this aggressive parameter setting to the specific fast following mode context, rather than applying it universally, thus resolving the contradiction between response speed and control stability.

AI summary
Provided are a method and apparatus for controlling a handheld gimbal, and a handheld gimbal. The method comprises: receiving an indication, input by a user, of entering a fast following mode; based on the indication of entering the fast following mode, updating control parameters of a camera component in one or more directions, wherein the control parameters of a camera component in one or more directions comprise the maximum following rate and acceleration of the camera component in one or more directions; and applying the updated control parameters of a camera component in one or more directions to control the rotation of one or more corresponding electric motors in a handheld gimbal, thus controlling the movement of the camera component in one or more directions. Where a gimbal handle needs to be rotated quickly for photography, the present invention can enable a camera component fixed on a handheld gimbal to quickly follow a target and perform photography smoothly.
