UAV Flight Control With Direction-Based Object Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing unmanned aerial vehicle (UAV) systems struggle to quickly detect specific objects in a wide range of surroundings due to the need for extensive image processing, which delays detection and compromises flight safety.
Innovation Solution
The UAV control system employs an image obtaining unit to capture surroundings, a movement direction obtaining unit to determine the UAV's direction, a specifying unit to identify a processing area based on this direction, and a processing unit to perform detection on that area, with additional factors like external force, attitude, and flight mode influencing the processing area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If image processing is performed for a wider range to capture all directions, then the coverage of surroundings is improved, but the detection speed is delayed
Solution Approach 1:
The patent divides the image processing task into segments by identifying and prioritizing specific regions of interest based on movement direction. Instead of processing the entire wide-angle image uniformly, the system segments the image into relevant areas (where objects are likely to appear based on UAV movement) and processes those segments with higher priority or detail, while reducing processing for less critical areas. This resolves the contradiction by maintaining wide coverage while accelerating detection through selective processing.
2Measurement precision
If image processing is performed on the entire image, then the detection accuracy is improved, but the processing time increases
Solution Approach 1:
The patent applies local quality by varying the processing intensity and focus across different regions of the image. Areas corresponding to the UAV's movement direction and potential object locations receive higher processing quality and more thorough analysis, while other areas receive reduced processing. This ensures high detection accuracy for critical regions while reducing overall processing time, effectively resolving the contradiction between accuracy and time.
3Speed
If the processing area is reduced to improve detection speed, then the response time is improved, but the detection reliability may be compromised
Solution Approach 1:
The patent employs dynamics by adaptively adjusting the processing area and focus based on real-time UAV movement direction and environmental conditions. The system dynamically identifies which regions require processing based on current movement vectors and prioritizes those areas, ensuring that the most relevant regions are always processed with appropriate thoroughness. This dynamic adaptation maintains detection reliability while optimizing speed by avoiding processing of irrelevant areas.
