UAV Storage Box Positioning With Lid-Exposed Marker Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for delivering goods using unmanned aerial vehicles face challenges in accurately unloading goods into designated storage boxes on autonomous vehicles, leading to reduced reliability and potential damage due to external factors like rain and wind.
Innovation Solution
The method involves an unmanned aerial vehicle capturing images of the autonomous vehicle's storage box, recognizing markers, adjusting its position based on image analysis, and using gripping members to accurately unload goods into the storage box, with communication between the vehicles to manage the lid's opening and closing for visibility of the marker.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the unmanned aerial vehicle unloads goods without accurate position adjustment, then the delivery speed is fast, but the goods may be lost or damaged due to rain and wind
Solution Approach 1:
The system performs preliminary position adjustment by capturing images, recognizing markers, and calculating distances before the actual goods unloading. This preliminary action ensures the unmanned aerial vehicle is correctly positioned over the storage box before releasing goods, preventing loss or damage while maintaining efficient delivery
Solution Approach 2:
The patent replaces manual positioning and mechanical alignment with automated image capture, marker recognition, and coordinate calculation systems. This substitution enables rapid, precise position adjustment without time-consuming manual intervention, resolving the contradiction between speed and accuracy
2Measurement precision
If the marker is always visible for position adjustment, then the positioning accuracy is high, but the security of the storage box is reduced
Solution Approach 1:
The marker is exposed only temporarily during the image capture and position adjustment phase, then covered again by the lid. This preliminary exposure limited to the necessary time window achieves accurate positioning while maintaining storage box security when not in use
Solution Approach 2:
The lid state is dynamically changed from closed to open only during the brief period when image capture and marker recognition are performed. This dynamic adjustment allows the marker to be visible for positioning while maintaining security for the majority of time when the lid remains closed

AI summary
Provided is a method for an unmanned aerial vehicle to handle goods in cooperation with an autonomous vehicle. The method comprises capturing, by the unmanned aerial vehicle, an image of the autonomous vehicle having a goods storage box, recognizing, by the unmanned aerial vehicle, a marker displayed in the goods storage box by analyzing the captured image, identifying, by the unmanned aerial vehicle, a region occupied by the marker on the captured image, adjusting a relative position of the unmanned aerial vehicle and the autonomous vehicle, wherein the marker displayed in the goods storage box is covered by a lid of the goods storage box and placed in a state that cannot be captured by the unmanned aerial vehicle, and the marker is exposed in a state that can be captured by the unmanned aerial vehicle only when the lid of the storage box is opened by communication between the unmanned aerial vehicle and the autonomous vehicle.
