Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current landmine detection methods are hazardous, time-consuming, and lack accuracy, relying heavily on subjective human interpretation and ground-based techniques that fail to effectively incorporate environmental factors and are limited by varying lighting conditions and weathering effects.
Innovation Solution
A computer-implemented method using aerial multispectral or hyperspectral image data processing, combining multiple spectral channels, filtering for high reflectance from buried or surface explosive devices, and applying AI-driven convolutional neural networks to generate heat maps for enhanced landmine detection, aiding human operators and reducing detection time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ground-based detection techniques are used, then detection can be performed, but the process is hazardous and time-consuming with limited accuracy
Solution Approach 1:
The patent replaces ground-based mechanical detection systems with aerial drone-based imaging systems. Drones equipped with cameras capture images of the terrain from above, eliminating the need for detectors to physically contact or closely approach potential landmine sites, thereby reducing hazard exposure and detection time while maintaining or improving accuracy through advanced image processing techniques.
Solution Approach 2:
The patent transitions from ground-level two-dimensional detection to aerial three-dimensional imaging. By capturing images from elevated drone positions, the system gains an additional spatial dimension for observation, allowing simultaneous coverage of larger areas and enabling detection of surface anomalies that may indicate landmine presence without the time and hazard constraints of ground-based methods.
2Measurement precision
If subjective human interpretation is used for landmine detection, then detection can be performed, but accuracy is limited by human subjectivity
Solution Approach 1:
The patent introduces an intermediary layer of automated image processing algorithms and AI models between the captured images and human operators. These intermediaries objectively analyze image data for anomalies, patterns, and features indicative of landmines, providing standardized, repeatable detection results that eliminate human subjectivity while maintaining system manageability through user-friendly interfaces.
Solution Approach 2:
The patent enables the detection system to perform self-analysis through automated algorithms that independently process images, identify potential landmine locations, and generate detection reports. This self-service capability reduces reliance on subjective human interpretation while the system remains accessible and controllable by operators through simplified interfaces, effectively balancing automation with usability.
3Adaptability or versatility
If ground-based techniques are used, then detection can be performed, but environmental factors and weathering effects limit effectiveness
Solution Approach 1:
The patent inverts the detection perspective from ground-level to aerial view. By observing the terrain from above, the system captures environmental context and weathering patterns that affect landmine detection differently than ground-based methods. This inverted perspective allows algorithms to account for and adapt to environmental variations, improving detection accuracy across diverse conditions while maintaining environmental adaptability.
