Camera Positioning Device Jitter Removal via Local Controller
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera tracking systems fail to accurately mimic the orientation of a remote driver, often transmitting jittery commands that result in unstable camera movements, limiting their ability to effectively track moving objects or capture panoramic images.
Innovation Solution
A positioning device with a holding element, wireless linkage, and local controller that interprets remote attitude commands, removes jitter, and generates precise local attitude commands to move a camera in tandem with a remote driver, using a combination of gyro, accelerometer, or magnetometer sensors, allowing for stable two-axis rotation and real-time image transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote attitude commands are transmitted directly to control camera orientation, then the camera can follow the remote driver's movements, but jitter in the commands causes unstable and inaccurate camera positioning
Solution Approach 1:
A local controller acts as an intermediary between the remote driver and the camera positioning system. The local controller receives remote attitude commands, processes them through filtering algorithms to remove jitter, and generates smooth local attitude commands that accurately reflect the driver's intent without transmitting the noise to the camera system.
Solution Approach 2:
The system performs preliminary processing of remote attitude commands before they are executed by the camera positioning mechanism. By pre-filtering and smoothing the commands in advance, the system prevents jitter from reaching the camera, ensuring stable positioning while maintaining responsive control.
2Speed
If the camera system responds directly to remote driver movements, then real-time tracking is achieved, but the transmitted jitter results in unstable image quality
Solution Approach 1:
The local controller serves as a mediator that decouples the remote driver's movements from the camera positioning. It processes commands through smoothing algorithms that eliminate high-frequency jitter while preserving the essential motion trajectory, thereby maintaining real-time tracking capability while ensuring image stability.
Solution Approach 2:
The system implements feedback mechanisms where the local controller continuously monitors remote attitude commands, compares them against desired stability criteria, and adjusts the local attitude commands accordingly. This feedback loop filters out jitter while maintaining the real-time tracking response.
3Device complexity
If simple command transmission is used from remote driver to camera, then system complexity is reduced, but the ability to remove jitter and provide stable tracking is compromised
Solution Approach 1:
The local controller is introduced as a relatively simple intermediary component that provides sophisticated jitter removal functionality. Rather than complicating the entire system, a dedicated local processing unit handles the filtering and command generation, keeping the overall architecture manageable while significantly improving tracking stability and reliability.

AI summary
A method and device are provided for positioning a mounted camera. The device includes a holding element that secures the mounted camera to the device, a wireless linkage at which remote attitude commands representing attitude changes of a remote driver are received, a local controller that interprets the remote attitude commands and generates local attitude commands that move the camera to mimic an orientation of the remote driver, and an attitude sensing element that senses a local attitude of the device. The attitude sensing element includes a gyro, an accelerometer, or a magnetometer, and jitter present in the remote attitude commands is removed and not passed on to the local attitude commands.
