Infrared Gimbal Tracking for Centered Maximum Temperature Points
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrared cameras mounted on unmanned aerial vehicles (UAVs) face challenges in maintaining the maximum temperature point at the center of the image frame due to dynamic objects and UAV movement, making it difficult for users to accurately locate and track temperature extremes in real-time applications such as firefighting and crop health monitoring.
Innovation Solution
A method and device that acquire the coordinates of the maximum temperature point in an image captured by an infrared camera and adjust the gimbal's rotation angle to keep the maximum temperature point centered within the image frame, ensuring it remains at a target position, which can be the image center, using a combination of coordinate acquisition, rotation angle determination, and gimbal control.

Engineering Contradiction Analysis
1Speed
If the UAV flies dynamically or objects move in the captured image, then the imaging system can capture dynamic scenes, but the maximum temperature point cannot remain at the center of the image frame
Solution Approach 1:
The system continuously detects the position of the maximum temperature point in the infrared image and feeds back this information to the gimbal control system. The gimbal adjusts its rotation angle based on this feedback to keep the maximum temperature point centered in the image frame, resolving the contradiction between dynamic UAV flight and precise temperature point location.
Solution Approach 2:
The gimbal system is made dynamic by enabling real-time rotation adjustments. Instead of a fixed imaging orientation, the gimbal can dynamically change its rotation angle to track the maximum temperature point, allowing the system to maintain measurement precision while the UAV flies at varying speeds.
2Measurement precision
If the maximum temperature point position is tracked in real-time, then the temperature monitoring accuracy is improved, but the system complexity increases due to additional control mechanisms
Solution Approach 1:
The gimbal system serves multiple functions: it provides stable image mounting and simultaneously enables maximum temperature point tracking. By making the gimbal rotatable and adding control capabilities, the same hardware structure achieves both stabilization and tracking functions, reducing overall system complexity while improving measurement precision.
3Ease of operation
If the gimbal rotation angle is adjusted to keep the maximum temperature point centered, then the observation usability is improved, but the response time to track moving targets increases
Solution Approach 1:
The system implements continuous tracking by constantly adjusting the gimbal rotation angle based on the real-time position of the maximum temperature point. This continuous adjustment ensures that the temperature point remains centered in the image frame without interruption, improving observation ease while minimizing tracking time through uninterrupted tracking action.

AI summary
A method for tracking a maximum temperature point includes acquiring a first pair of coordinates of a maximum temperature point in a current frame of image sensed by an infrared camera, determining a rotation angle of a gimbal equipped with the infrared camera according to the first pair of coordinates of the maximum temperature point in the current frame of image and a pair of coordinates of a target position of the maximum temperature point in a subsequent frame of image, and controlling the gimbal to rotate according to the rotation angle, so as to adjust the maximum temperature point in the subsequent frame of image captured by the infrared camera to be located at the target position.
