UAV Hand Gesture Flight Control Without External Controllers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current UAV control methods require additional equipment and complex user interaction, leading to increased costs and poor human-computer interaction, as they necessitate operation of external devices rather than direct user gestures.
Innovation Solution
A UAV control method and device that utilize a photographing device to capture images, determine the location of a target object's hand within the image, and control the UAV based on this information, allowing for gesture-controlled flight operations such as altitude adjustment, flying around, and approaching or receding from the target object.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control handles or touch screen devices are used to control UAVs, then control functionality is achieved, but additional equipment is required which increases costs and operational complexity
Solution Approach 1:
The patent extracts the control interface from external devices (remote controls, mobile phones) and integrates it directly into the UAV system through the photographing device. The hand gesture recognition functionality is built into the UAV itself, eliminating the need for separate control equipment while maintaining full control capabilities.
Solution Approach 2:
The photographing device is given multiple functions: it not only captures images for photography purposes but also serves as the control interface by recognizing hand gestures. This multi-functionality eliminates the need for dedicated control devices, reducing overall system complexity while maintaining ease of operation.
2Ease of operation
If additional control equipment is used, then control functionality is provided, but user interaction efficiency decreases due to the need to learn and operate external devices
Solution Approach 1:
The UAV system provides control functionality through itself rather than requiring external devices. The photographing device on the UAV directly captures and recognizes hand gestures, allowing users to control the UAV with intuitive gestures without needing to learn complex remote control operations or mobile application interfaces.
3Device complexity
If hand gesture recognition is implemented using the photographing device, then external control equipment is eliminated, but image processing complexity increases
Solution Approach 1:
The patent introduces an intermediary processing system that bridges the photographing device and the control functions. The processor analyzes the captured images to detect hand gestures and translates them into control commands, simplifying the overall detection and measurement process while eliminating external control equipment.

AI summary
A control method for controlling UAV includes obtaining an image captured by a photographing device, determining a location of a target object hand in the image, determining location information of the hand of the target object based on the location of the hand in the image, and controlling the UAV based on the location information of the hand of the target object.
