Handheld Gimbal Selfie Tracking With Real-Time Onboard Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing handheld gimbals face challenges in stabilizing the capture of moving objects during shooting, especially in bumpy conditions, and require additional terminals for real-time image observation, making it cumbersome for users to achieve desired shooting effects, particularly when taking selfies.
Innovation Solution
A handheld gimbal with a built-in display screen and controller that determines the selfie mode, tracks and adjusts the shooting device based on target object characteristic information, and displays the shooting image in real-time, allowing for automatic tracking and composition adjustments without the need for external terminals.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual tracking is used to capture moving objects, then the user can control the shooting device, but the shooting stability deteriorates when the object is always in motion or the user is in a bumpy state
Solution Approach 1:
The shooting device performs automatic tracking of the target object using image processing and object detection algorithms, eliminating the need for manual tracking operations. The system automatically identifies and follows the target object in consecutive frames, maintaining shooting stability even when the user is in a bumpy state or the object is in motion.
2Length of moving object
If an extension stick is used to take selfies, then the shooting distance is extended, but the user cannot see the shooting image on the display screen for composition
Solution Approach 1:
The system uses a terminal device (such as a smartphone) as an intermediary to display the shooting image captured by the shooting device. The terminal device receives the image data via wireless communication and displays it on its screen, allowing the user to view and compose the selfie image even when using an extension stick that prevents direct viewing on the shooting device's display screen.
3Loss of information
If a terminal device is used to observe the shooting image in real time, then the user can view the image, but the operation becomes cumbersome and inconvenient
Solution Approach 1:
The system merges the display function of the terminal device with the shooting device by establishing a direct wireless connection. The terminal device's display screen is utilized to show the shooting image in real-time, combining the observation function into the existing shooting system and eliminating the need for separate observation equipment, thereby improving operation convenience while maintaining real-time image viewing capability.
4Reliability
If automatic tracking is implemented, then shooting stability is improved, but the device complexity increases
Solution Approach 1:
The system replaces complex mechanical tracking mechanisms with electronic image processing and software-based object detection algorithms. The automatic tracking is achieved through computational methods that analyze image data and calculate target position changes, substituting mechanical complexity with electronic and software solutions that are more compact and controllable.
