Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current target tracking methods fail to accurately recognize and track objects in images produced by certain shooting devices, particularly those using thermal infrared imaging, due to insufficient texture information, leading to poor tracking performance.
Innovation Solution
A target tracking method utilizing a dual-light camera system where a thermal infrared shooting device is paired with a visible light shooting device, allowing the system to adjust its attitude based on the tracking position area in the visible light image to maintain the target within the thermal infrared frame, even if the target cannot be accurately recognized in the thermal infrared image.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If thermal infrared shooting device is used for target tracking, then the shooting device can operate in low-light or no-light conditions, but the target object cannot be accurately recognized due to insufficient texture information
Solution Approach 1:
The patent combines a thermal infrared shooting device and a visible light shooting device into a unified shooting system. The thermal infrared device provides low-light capability while the visible light device provides texture information for accurate recognition. The system merges the strengths of both devices to achieve both low-light operation and accurate target recognition simultaneously.
2Measurement precision
If visible light shooting device is used for target tracking, then the target object can be accurately recognized due to rich feature information, but the shooting device cannot operate in low-light or no-light conditions
Solution Approach 1:
The patent merges the visible light shooting device with the thermal infrared shooting device in a dual-mode system. The visible light device ensures accurate target recognition when lighting conditions permit, while the thermal infrared device takes over in low-light conditions. The system dynamically switches or combines modes based on environmental lighting conditions.
3Device complexity
If single shooting device is used, then the device structure is simple, but the tracking performance is poor when target cannot be recognized in the image
Solution Approach 1:
The patent creates a multi-functional shooting device that can operate in both thermal infrared mode and visible light mode. This universal device can adapt to different environmental conditions and target types, ensuring reliable tracking performance whether the target is visible in thermal or visible spectrum. The system selects the appropriate imaging mode based on the specific tracking requirements and environmental conditions.
