UAV Straight-Line Flight Control With Real-Time Route Correction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing UAV control methods face challenges in maintaining accurate flight routes, especially during larger plot tasks, as manual control can lead to deviations and require high pre-surveying, while automated systems lack real-time adaptability to operational changes.
Innovation Solution
A method and apparatus for controlling UAV flight that determines the starting position and nose direction, allowing the UAV to fly along a straight line and adjust its route based on real-time instructions from a remote control apparatus, enabling manual fine adjustments and automatic navigation to correct deviations without extensive mapping.

Engineering Contradiction Analysis
1Ease of operation
If manual control is used to control the UAV to fly along a trajectory, then the operator can flexibly control the UAV in small plot operations, but the UAV easily deviates from the flight route when performing larger plot tasks
Solution Approach 1:
The patent combines manual control operations with automatic navigation functions into a unified control system. The operator can issue high-level route adjustment instructions manually while the system automatically calculates and executes the corrected flight path, merging the flexibility of manual control with the precision of automatic navigation.
Solution Approach 2:
The system continuously monitors the UAV's actual flight position and compares it with the planned route, then provides real-time feedback by calculating deviation and generating corrective route adjustments. This closed-loop feedback mechanism maintains flight accuracy while preserving operator flexibility.
2Manufacturing precision
If automated route control is used, then the operation is accurate and does not require people to participate, but it needs to be surveyed in advance and cannot adapt in real-time to operational changes
Solution Approach 1:
The system transitions from a static pre-planned route to a dynamic route that can be adjusted in real-time. The route parameters are not fixed but can be modified during flight based on operator instructions and actual operational conditions, enabling the system to adapt while maintaining accuracy.
Solution Approach 2:
The system automatically calculates route deviations and generates correction instructions without requiring manual intervention for every adjustment. When the operator provides a high-level adjustment instruction, the system self-services by computing the optimized path and executing the correction, combining automatic adaptation with operator oversight.
3Extent of automation
If automated route control is used, then the operation does not require people to participate, but high pre-surveying and mapping requirements are needed
Solution Approach 1:
Instead of requiring complete and precise pre-surveying of the entire operation area, the system uses partial surveying data and combines it with real-time position feedback and dynamic route adjustment. This reduces the burden of pre-surveying while maintaining navigation accuracy through ongoing corrections.

AI summary
A method and apparatus for controlling the flight of an Unmanned Aerial Vehicle (UAV) are provided. The method includes: determining a starting flight position where a UAV is parked currently and a nose direction of the UAV (101); starting off from the starting flight position, and flying along a straight line in the nose direction (102); and when receiving a route adjustment instruction during the flight of the UAV, adjusting an air route of the UAV according to the route adjustment instruction (103). During the flight, an operator can correct an air route via a remote control apparatus without surveying and mapping when detecting that the UAV is flying off course; and the operator can make the UAV precisely fly along a desired straight line by means of simple operations.
