UAV Coordinate Transformation for Intuitive Target Tracking Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Controlling unmanned aerial vehicles (UAVs) while operating attached imaging equipment is challenging due to the need to manage flight parameters like distance, spatial orientation, and stability, especially when the target is in motion or during complex maneuvers, as the user's spatial frame of reference differs from the UAV's control system.
Innovation Solution
A method and system that allow users to control UAVs from their own perspective by translating input signals from their coordinate system to the UAV's coordinate system, enabling intuitive commands like 'go up' or 'turn' to be converted into precise flight control signals, thereby simplifying the control of flight parameters such as pitch, yaw, and throttle.

Engineering Contradiction Analysis
1Ease of operation
If the user directly controls the UAV using traditional coordinate systems, then the control signals can be processed by the UAV's flight control system, but the user's spatial frame of reference differs from the UAV's control system, making it difficult to precisely control flight parameters and operate imaging equipment simultaneously
Solution Approach 1:
The patent introduces a coordinate transformation module as an intermediary between the user's perspective coordinate system and the UAV's flight control coordinate system. This module transforms user inputs from the first coordinate system to the second coordinate system, enabling intuitive user control while maintaining precise flight parameter control. The transformation module acts as a mediator that reconciles the different spatial reference frames without requiring the user to understand complex aviation coordinate systems.
2Adaptability or versatility
If the user tries to control both the UAV flight and the attached imaging equipment, then more tasks can be performed, but it becomes difficult to effectively operate imaging equipment while simultaneously controlling distance, spatial orientation, and flight stability
Solution Approach 1:
The patent segments the control system into independent modules: a flight control module that handles UAV movement based on transformed coordinate inputs, and an imaging equipment control module that operates independently. This segmentation allows the user to control flight parameters and imaging equipment separately without interference, reducing the cognitive load and complexity of simultaneous multi-parameter control while maintaining versatility.
3Adaptability or versatility
If the UAV performs complex flight maneuvers, then more flight capabilities are demonstrated, but the user's spatial frame of reference differs from the UAV's control system, making control more challenging
Solution Approach 1:
The patent implements a dynamic coordinate transformation system that continuously adapts to the UAV's current flight state and orientation. As the UAV performs complex maneuvers and changes its attitude, the transformation module dynamically recalculates the coordinate mapping between the user's perspective and the UAV's flight control system. This dynamic adaptation ensures that user inputs remain intuitive and precise regardless of the UAV's flight phase or maneuver complexity.

AI summary
A method for controlling a movable object includes receiving a user input indicative of a command to adjust a perception of a target while tracking the target, determining a subsequent perception of the target based on the user input, and generating one or more control signals to move the movable object based on the subsequent perception of the target.
