| description | [Introduction] With the continuous and rapid growth of the number of tree barrier inspections, visible light aerial photogrammetry has become the most important inspection method for hidden dangers of tree barriers in transmission lines of power supply bureaus in various cities. Since airborne laser radar cannot perform rapid iteration on a large number of point clouds, it is difficult to obtain high-precision point cloud power lines with visible light aerial photogrammetry. In the case of flourishing trees, it is difficult to comprehensively judge and analyze the relationship between tree tops, tree crowns and power lines, which results in problems such as misjudgment and omission of hidden dangers of tree barriers in the process of power line inspection. In order to solve this kind of problem, a solution of acquiring vectorized power line by laser radar is proposed. Through the intelligent analysis of vegetation information collected by multi-period visible light aerial photogrammetry, the solution of tree barrier is obtained. [Method] In view of the comprehensive situation that the image data collected by visible light aerial photogrammetry couldn't obtain high-precision point cloud power lines, it was difficult to simultaneously and comprehensively analyze the relationship between tree tops, tree crowns and power lines, and laser point cloud data couldn't be quickly iterated in large quantities, an overhead line tree barrier rapid analysis and processing system for multi-source spatio-temporal data of vectorized power lines was developed, which was suitable for the current conventional tree barrier inspection means, had comprehensive functions, saved resources, and was suitable for transmission and distribution networks. [Result] Through the three-dimensional real scene display of laser point cloud and visible light image data, the function of identifying and analyzing hidden dangers of tree barriers in power lines is realized. The vectorized power lines are complete and accurate. At the same time, combined with oblique photography technology, the data analysis of the hidden dangers of tree barriers results can identify 100% of the number of tree barrier hidden dangers. [Conclusion] The technical solution is accurate and effective, improves the efficiency and accuracy of the inspection of hidden dangers of tree barriers, and can provide guidance for practical application. |
