A method for controlling UAV flight using a communicative connection between a mobile control device and the UAV, incorporating a directional distance measuring module, which receives environment data and generates a 3D point cloud representation, allowing for intuitive control commands to be translated into precise movements, such as maintaining a constant distance from objects and aligning the main view direction, through touch inputs on a touch-sensitive display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a UAV is equipped with environmental sensor systems and complex control systems for semi-autonomous operation, then the functionality and task complexity increase, but the ease of operation and controllability deteriorate
Solution Approach 1:
The patent introduces a mobile control device as an intermediary between the user and the UAV's complex control system. This device provides a simplified graphical user interface that translates intuitive user gestures into precise control commands for the UAV's propulsion units and sensor systems, thereby maintaining ease of operation while enabling complex semi-autonomous functions.
Solution Approach 2:
The system implements feedback mechanisms where the mobile control device receives and displays real-time sensor data from the UAV, including 3D point cloud information and environmental measurements. This feedback loop allows users to intuitively understand the UAV's environment and control its movements without needing to comprehend the underlying complex control algorithms.
2Measurement precision
If the control system processes complex environmental data to enable precise semi-autonomous navigation, then the measurement precision and navigation accuracy improve, but the device complexity increases
Solution Approach 1:
The patent divides the complex data processing functionality into separate modular components: environmental sensor systems for data collection, processing units for 3D point cloud generation and analysis, and control systems for navigation. This segmentation allows each component to specialize in specific tasks, improving measurement precision while managing overall system complexity through modular architecture.
Solution Approach 2:
The system creates simplified representations of the complex 3D environment by generating point cloud data and visualizing it through the mobile control device's display. This copying approach allows the system to process detailed environmental information for precise navigation while presenting a simplified interface to the user, effectively managing the complexity-gap between raw sensor data and user interaction.
3Productivity
If the UAV performs detailed surveying and digitizing tasks, then the productivity and task completion quality improve, but the time required for data collection and processing increases
Solution Approach 1:
The patent implements preliminary action by pre-processing environmental data into 3D point cloud representations during the surveying flight itself, rather than performing all processing after data collection. The system continuously generates and updates spatial models during flight, enabling real-time navigation decisions and reducing post-processing time, thereby improving overall productivity without sacrificing task completion quality.
