Image Stabilization Calibration With Motor Motion Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image stabilization mechanisms, such as gimbals, face challenges in calibration processes due to motor inactivity, leading users to mistakenly interrupt ongoing calibration, which can negatively impact the mechanism's operation.
Innovation Solution
A method where a control system sends commands to thermally condition sensors and drive motors to move the imaging device during calibration, providing user indication of ongoing processes through motor movement, ensuring uninterrupted calibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the control system drives motors during sensor calibration, then the user is notified of ongoing calibration through motor movement, but the calibration process takes longer to complete
Solution Approach 1:
The patent uses motor movement as an intermediary signal to communicate calibration status to the user. Instead of adding a separate notification system, the existing motor activity serves as a visual/tactile indicator that calibration is in progress, preventing user interruption while accepting extended calibration time
2Measurement precision
If the control system waits for thermal conditioning before calibrating sensors, then calibration accuracy is improved, but the overall calibration time increases
Solution Approach 1:
The patent performs thermal conditioning of sensors as a preliminary action before actual calibration. By pre-conditioning the sensors to the correct temperature, the subsequent calibration achieves higher accuracy. The system overlaps this thermal conditioning with motor-driven notifications, so the preparation time does not extend the perceived calibration duration
3Loss of information
If the control system keeps motors active during calibration, then user notification is continuous, but energy consumption increases
Solution Approach 1:
The patent employs periodic motor activation during calibration rather than continuous operation. Motors are driven in cycles to provide intermittent notification of calibration progress, which maintains user awareness while significantly reducing energy consumption compared to continuous motor operation

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The method ensures complete and accurate calibration of image stabilization mechanisms by preventing user intervention during the process, maintaining the stability and precision of the imaging device's orientation.
Implementation Method 1
The control system sends a command to thermally condition one or more sensors to a predetermined temperature
Data Source
AI summary
The disclosure describes systems and methods for calibrating an image stabilization mechanism. One method includes a control system sending a command to thermally condition one or more sensors to a predetermined temperature. During thermal conditioning to the predetermined temperature, the control system sends a command to drive one or more motors of the image stabilization mechanism to cause movement of an imaging device coupled to the image stabilization mechanism. After thermal conditioning to the predetermined temperature, the control system sends a command to stop driving the one or more motors of the image stabilization mechanism to stop movement of the imaging device coupled to the image stabilization mechanism. After stopping the driving of the one or more motors, the control system sends a command to calibrate the one or more sensors.
