Engineering Contradiction Analysis
1Extent of automation
If manual site investigation is used to inspect vegetation around electric power lines, then the inspection can be performed with simple equipment, but the process consumes大量 manual labor and material resources with low automation and low accuracy
Solution Approach 1:
The patent replaces manual mechanical inspection with an automated LiDAR-based point cloud processing system. The laser scanner automatically captures spatial data, and computer algorithms automatically classify and analyze the point cloud data to identify hazardous vegetation, eliminating the need for manual site investigation while significantly improving automation degree.
Solution Approach 2:
The patent creates a digital copy of the physical environment through LiDAR point cloud data. This virtual model allows automated analysis and classification of vegetation without physically visiting the site, enabling high-accuracy hazard detection while reducing manual labor and resource consumption.
2Measurement precision
If manual site investigation is used to detect hazardous areas, then the equipment requirements are minimal, but the accuracy of hazard detection is relatively low
Solution Approach 1:
The patent replaces imprecise manual inspection with automated LiDAR technology and point cloud classification algorithms. The system automatically detects hazardous vegetation by comparing point cloud data against predefined safety thresholds, achieving high measurement precision while eliminating the need for extensive manual labor and material resources.
Solution Approach 2:
The system performs self-assessment by automatically classifying point cloud data into safe and hazardous categories using machine learning algorithms. The automated classification process independently identifies vegetation that exceeds safety distances without requiring human intervention, thereby improving detection accuracy while reducing resource consumption.
3Productivity
If automated point cloud processing is implemented, then automation degree and accuracy are improved, but the system complexity and processing requirements increase
Solution Approach 1:
The patent segments the complex point cloud processing task into distinct classification stages: safe area classification, hazardous area identification, and individual tree segmentation. This modular approach improves processing efficiency by allowing parallel computation and specialized algorithms for each stage, while managing system complexity through structured data flow and intermediate results.

AI summary
A method, an apparatus and an electronic device for processing point cloud data and a computer readable storage medium are disclosed. The method includes: receiving first point cloud data acquired by a laser scanner; classifying the first point cloud data to obtain second point cloud data which is classified; judging if the second point cloud data at least comprises target point cloud data, and whether a distance between other point cloud data in the second point cloud data and the target point cloud data is smaller than a first preset threshold value; if yes, determining the other point cloud data as hazardous point cloud data.
