Solution Overview
Problem
Current methods for detecting and managing vegetation near power lines are inefficient and inaccurate, relying on human visual inspection, which is time-consuming and prone to errors, and do not effectively address the risks of electrical arcing and power outages caused by trees or other vegetation contacting or being close to power lines.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If human visual inspection is used to detect vegetation near power lines, then the method is simple to implement, but it is time-consuming and prone to errors
Solution Approach 1:
The patent replaces manual visual inspection with an automated optical detection system using drones equipped with cameras and image processing algorithms. The system captures images of power line corridors and automatically identifies vegetation encroachment, substituting human mechanical inspection with automated optical-mechanical systems to improve both accuracy and efficiency
Solution Approach 2:
The system enables self-service detection by automatically processing images to identify hazardous vegetation without requiring continuous human intervention. The image processing algorithms autonomously analyze captured images, detect vegetation near power lines, and generate reports, allowing the system to serve itself in the detection task while reducing dependency on human inspectors
2Reliability
If manual inspection methods are used, then the system complexity is low, but the reliability of hazard detection is insufficient
Solution Approach 1:
The patent replaces unreliable manual inspection with automated image processing systems that consistently identify vegetation hazards. The system uses computer vision algorithms to analyze drone-captured images, automatically detecting vegetation encroachment with higher reliability and consistency than human inspectors, justifying the increased system complexity
Solution Approach 2:
The patent introduces an intermediary image processing system between the physical vegetation and the detection outcome. Rather than directly observing hazards, the system uses captured images as intermediaries to indirectly detect and analyze vegetation encroachment, improving detection reliability through automated image analysis
3Measurement precision
If automated spectral analysis is implemented, then detection accuracy improves, but the use of energy and system complexity increase
Solution Approach 1:
The patent applies partial action by using spectral analysis selectively only for vegetation detection rather than analyzing all spectral characteristics. The system processes only the necessary spectral bands required for identifying vegetation encroachment, avoiding excessive energy consumption while maintaining detection precision
Solution Approach 2:
The patent extracts only the essential spectral information needed for vegetation detection from the full spectral range. By isolating and analyzing only the relevant spectral characteristics associated with vegetation, the system reduces energy consumption while preserving detection accuracy

AI summary
Embodiments of the present invention are directed to a computer-implemented method for detecting vegetation near a power line. A non-limiting example of the computer-implemented method includes detecting the spectral characteristics of a target location. The spectral characteristics can be used to detect a tree at the target location. The location of the power lines that are within a buffer distance of the tree can be detected. Given that the tree is within a buffer distance, a risk value can be calculated for the tree. The risk value can convey the likelihood that the tree will contact the power line. If the risk is above a threshold amount, a work order can be issued to direct a crew to trim or cut the tree to prevent it from contacting the power line.
