Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous orbiting technologies for UAVs rely heavily on GPS signals, making it difficult to achieve precise orbiting in regions with poor GPS coverage, such as indoors, and require high operator skill for optimal photographing results.
Innovation Solution
An autonomous orbiting method and device that utilizes a binocular camera assembly to obtain a target footage, determine the flying height and spatial distance to an orbited object, and adjust the flight direction in real-time based on the optical axis direction, allowing for GPS-independent orbiting and improved photographing effects.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS-based autonomous orbiting is used, then autonomous orbiting function is provided, but it cannot achieve precise orbiting in regions with poor GPS coverage
Solution Approach 1:
The patent introduces visual markers as intermediary objects that mediate between the UAV and the orbited object. These markers serve as reference points that the UAV can track and follow, enabling autonomous orbiting without relying on GPS signals. The markers act as a bridge that transfers positioning information from the ground to the air, solving the problem of GPS-denied environments.
Solution Approach 2:
The patent replaces the GPS-based mechanical positioning system with a visual-based tracking system. Instead of relying on satellite signals and computational geometry, the system uses visual markers that can be directly observed and tracked by the UAV's camera, substituting optical detection for radio signal-based positioning.
2Measurement precision
If manual orbiting operation is used, then precise trajectory control can be achieved, but high operator skill is required
Solution Approach 1:
The patent enables the UAV system to serve itself by automatically tracking visual markers and computing its own trajectory. The UAV autonomously determines its position relative to the orbited object by tracking the visual marker, eliminating the need for manual pilot intervention. The system performs self-positioning and self-navigation, making precise orbiting accessible to users regardless of their operational skill level.
Solution Approach 2:
The patent implements a feedback mechanism where the UAV continuously captures images of the visual marker, processes the marker's position in the image, and adjusts its flight trajectory accordingly. This closed-loop visual feedback system automatically corrects positioning errors and maintains precise orbiting without requiring manual adjustment by the operator.
