Automatic Clearance Anomaly Detection for Transmission Line Corridors Utilizing UAV-Borne LIDAR Data

Abstract: Transmission line corridor (i.e., Right-of-Ways (ROW)) clearance management plays a critically important role in power line risk management and is an important task of the routine power line inspection of the grid company. The clearance anomaly detection measures the distance between the power lines and the surrounding non-power-facility objects in the corridor such as trees, and buildings, to judge whether the clearance is within the safe range. To find the clearance hazards efficiently and flexibly, this stu… Show more

“…Table 3 shows how the cropping was done for each Landsat 8 scene. In order to quantitatively validate the proposed strategy, we used the metrics accuracy, precision, recall [15], and F-measure [82] for which, TP are true positives, i.e., images in which incongruences are truly detected; TN are true negatives, i.e., images in which congruences are truly detected; FN are false negatives, i.e., images in which congruences are falsely detected; FP are false positives, i.e., images in which incongruences are falsely detected. Accuracy measures the efficiency of results and is represented by Equation (23), for which M is the number of images.…”
