Handheld Gimbal Side-Shooting Detection via Attitude Difference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Handheld gimbals struggle to accurately and quickly recognize user adjustments for switching between different shooting modes, particularly in side shooting scenarios, due to limitations in attitude detection and handling of the user's operation.
Innovation Solution
A control method for a handheld gimbal that includes a rotating assembly and a handle, which includes a rotating assembly connected to the handle, which includes a rotating assembly configured to carry a shooting device and drive it to rotate, and a control device with a processor to determine the attitude difference between the rotating assembly and the handle to determine the shooting mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional attitude detection methods are used, then the device structure remains simple, but the recognition accuracy of shooting modes is insufficient
Solution Approach 1:
The patent segments the attitude detection by separately acquiring attitudes of the rotating assembly and handle, then calculating their difference. This segmentation enables precise mode recognition through differential analysis without requiring a completely new detection system.
Solution Approach 2:
The patent changes the detection parameter from absolute attitude to relative attitude difference between rotating assembly and handle. This parameter transformation enables accurate identification of shooting modes while utilizing existing attitude detection capabilities.
2Measurement precision
If complex attitude detection algorithms are implemented, then the shooting mode recognition becomes accurate, but the response speed decreases
Solution Approach 1:
The patent extracts only the essential information needed for mode recognition by calculating the attitude difference between rotating assembly and handle. This extraction approach avoids complex full-state analysis while achieving accurate and fast mode identification.
Solution Approach 2:
The patent performs preliminary attitude acquisition of both rotating assembly and handle before mode determination. This preliminary action prepares the data in advance, enabling rapid mode recognition when shooting mode switching is needed.
3Ease of operation
If manual switching between shooting modes is required, then the control system remains simple, but the ease of operation deteriorates
Solution Approach 1:
The patent enables the gimbal to automatically identify shooting modes by itself through attitude difference detection, eliminating the need for manual mode switching. The system serves itself by autonomously determining the appropriate shooting mode based on detected attitudes.
Solution Approach 2:
The patent implements feedback by continuously monitoring the attitude difference between rotating assembly and handle, and using this feedback to automatically determine and switch shooting modes. This closed-loop feedback enables convenient automatic mode adaptation.
