UAV Multi-Object Following Control for Framed Group Imaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UAVs are limited in their ability to follow multiple target objects, restricting their application in scenarios like group photography and games involving multiple players.
Innovation Solution
A control method and terminal for UAVs that receive and display images, detect user selections of multiple objects, and adjust the UAV's movement to keep these objects within the imaging frame, using voice or touch inputs to determine following instructions and control the UAV's movement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UAV follows a single target object using conventional technology, then the control system is simple and easy to operate, but the UAV cannot follow multiple target objects, limiting the photograph scenes
Solution Approach 1:
The control terminal segments the following task by allowing users to select multiple independent target objects individually. Each selected object becomes a separate following target, enabling the UAV to track multiple objects simultaneously while maintaining simple individual control for each target.
Solution Approach 2:
The following control module is designed with multi-functionality to handle both single-target and multi-target following scenarios. The same control interface and processing logic accommodate varying numbers of target objects, making the system adaptable to different photographing scenes without requiring separate control systems.
2Adaptability or versatility
If the UAV is designed to follow multiple target objects, then the photograph scenes are expanded, but the control interface and object selection become more complex
Solution Approach 1:
The control terminal automatically displays detected target objects in the real-time image stream, allowing users to directly select from visually presented options. The system self-updates the list of available targets based on current detection, reducing the need for manual configuration and simplifying the selection process for multi-object following.
3Area of stationary object
If the UAV tracks multiple objects simultaneously, then the imaging coverage is expanded, but maintaining all objects in the imaging frame becomes more difficult
Solution Approach 1:
The UAV's imaging frame is dynamically adjusted to accommodate multiple target objects. The system continuously monitors the positions of all selected targets and automatically modifies the frame composition, zoom level, and pan/tilt angles to keep all objects within the visible area, adapting to changing scene configurations in real-time.

AI summary
The present disclosure provides a following control method. The method includes receiving and displaying an acquired image acquired by an imaging device of an unmanned aerial vehicle (UAV); detecting a user's selection operation on two or more objects in the image; determining a following instruction based on the detected selection operation; and controlling the UAV to follow the two or more followed objects indicated by the following instruction so that the two or more followed objects are in an imaging frame of the imaging device.
