Tracking and evaluation method focusing on continuity of power line based on three-dimensional point cloud data

Abstract

Poles and overhead power lines have been common, and maintaining them is necessary. Increasingly, mobile mapping system (MMS) based on integration of various positioning, navigation and imaging data collection sensors is used to maintain the complex structure of power lines. However, MMS algorithms are still a work in progress and most limit measurement environments. Therefore, our purpose is to develop an evaluation method that can handle various challenging scenarios such as complicated configurations, ground slopes on a real world scale.In this paper, we propose a new algorithm for performing efficient extraction and tracking of powerlines from a three-dimensional point cloud data. Our algorithm focuses on the continuity of power lines, and three characteristic properties are used in the algorithm process: Dense point cloud, small color difference, and small light-intensity difference. Experimental results show that proposed method which focuses on the continuity of power lines is effective.
