Cooperative Aircraft Tracking for High-Low Altitude Target Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Aircrafts face challenges in accurately identifying and tracking target objects due to limitations in camera pixels and processor performance, leading to a trade-off between flying height and detail features, where excessive closeness results in loss of object location and vagueness in images.
Innovation Solution
A method and system involving two aircrafts, where one aircraft adjusts to a high-altitude area based on location information from a second aircraft in a low-altitude area, using feature parameters to track and identify the target object, allowing for high-low altitude cooperation to maintain clear images and accurate positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the aircraft reduces flying height to get close to the target object for photographing, then detail features of the target object can be identified, but the target object can easily get lost and location tracking becomes difficult
Solution Approach 1:
The patent divides the tracking and identification task into two segments: one aircraft (first aircraft) is responsible for tracking the target object at high altitude to maintain location information, while another aircraft (second aircraft) is responsible for capturing detail features at low altitude. This segmentation allows each aircraft to specialize in one function, resolving the contradiction between tracking reliability and detail identification precision.
2Reliability
If the aircraft raises flying height to get away from the target object for photographing, then the target object location can be easily obtained and tracked, but detail features are sacrificed and identification accuracy decreases
Solution Approach 1:
The patent merges the capabilities of two aircraft to achieve both high-altitude tracking and low-altitude detail capture simultaneously. The first aircraft at high altitude provides continuous location tracking, while the second aircraft at low altitude captures detailed features. By combining their functions, the system achieves both reliable tracking and accurate detail identification without the trade-offs of a single aircraft.
3Device complexity
If a single aircraft is used for both tracking and identification, then device complexity is reduced, but the aircraft must constantly adjust position causing loss of location information and vague images
Solution Approach 1:
The patent segments the functions between two aircraft: the first aircraft maintains high-altitude tracking to preserve location information, while the second aircraft performs low-altitude detail identification. This functional segmentation eliminates the need for a single aircraft to constantly adjust position between tracking and identification modes, thereby maintaining location information reliability.

AI summary
Disclosed are a tracking and identification method and system and an aircraft. The method includes: obtaining, by a first aircraft, a first feature parameter of a target object; if image data captured by the first aircraft does not match the first feature parameter, adjusting the first aircraft to a predetermined high-altitude area relative to the target object according to location information of a second aircraft that is sent by the second aircraft or location information of the target object, where the second aircraft is in a predetermined low-altitude area relative to the target object, and image data captured by the second aircraft matches a second feature parameter of the target object. The first aircraft in the predetermined high-altitude area and the second aircraft in the predetermined low-altitude area in embodiments of the present invention form high-low altitude cooperation and are respectively configured to track and identify the target object, thereby implementing transfer of location information between two or more aircrafts as well as tracking and identifying the target object.
