Handheld Gimbal Mode Switching for Stable Walking Shots
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld gimbals require users to adjust numerous control parameters, making it difficult to ensure stability of the photographing assembly during movement due to excessive complexity in parameter adjustments and interactions.
Innovation Solution
A gimbal system with an adjustment mechanism and a processor that selects an operation mode based on a mode selection activation condition, including control instructions or attitude change parameters, to control the gimbal's angular velocity, reducing shaking by responding at a lower speed in walk mode and increasing responsiveness in sensitive mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If users manually adjust multiple control parameters to control gimbal rotations, then the photographing assembly can be controlled to stay at a determined attitude, but the complexity of parameter adjustment increases and stability cannot be ensured
Solution Approach 1:
The gimbal control system automatically selects operation modes and adjusts control parameters based on detected attitude change parameters (angular velocity, angular acceleration) without requiring manual user intervention. The processor autonomously determines whether to apply first or second control parameter sets, eliminating the burden of manual parameter adjustment while maintaining stability.
Solution Approach 2:
The system dynamically changes control parameters based on operation modes. Two distinct control parameter sets are defined: first control parameters for normal operation and second control parameters for sensitive operation. The processor switches between these parameter sets based on detected attitude change characteristics, optimizing stability for different motion scenarios.
2Speed
If the gimbal responds quickly to attitude changes, then responsiveness is improved, but shaking increases during walking or normal movement
Solution Approach 1:
The gimbal control system dynamically adjusts its responsiveness based on the operation mode. In normal operation mode, the system uses first control parameters with lower responding speed to reduce shaking during walking. In sensitive operation mode, the system switches to second control parameters with higher responding speed for quick attitude adjustments. This dynamic adaptation resolves the contradiction between responsiveness and shaking reduction.
Solution Approach 2:
Different control parameter characteristics are applied to different operation scenarios. The system identifies the current operation mode based on attitude change parameters and applies locally optimized control parameters: first control parameters for normal walking scenarios and second control parameters for sensitive scenarios requiring quick response. This localized parameter optimization eliminates the need for a single fixed responding speed.
3Adaptability or versatility
If the gimbal uses a single control parameter set, then the system is simpler to operate, but it cannot adapt to different operation scenarios such as walking vs. sensitive movements
Solution Approach 1:
The gimbal control system achieves multi-functionality by implementing multiple operation modes (normal operation mode and sensitive operation mode) that can adapt to different usage scenarios. The processor universally handles both modes using the same hardware platform, switching between first and second control parameter sets based on detected attitude change parameters, providing versatility without requiring separate systems for each mode.
Data Source
AI summary
An apparatus for controlling a gimbal includes one or more processors individually or collectively configured to determine an operation mode of the gimbal according to a mode selection activation condition. The operation mode includes a walk operation mode or a sensitive operation mode. the one or more processors are further configured to, in response to determining that the operation mode is the walk operation mode, control the gimbal to adjust attitude at a lower responding speed than in the sensitive operation mode.
