Abstract

Abstract: This paper addresses the challenge of accurately measuring the tilt angle of power towers, which is limited by low computational efficiency, tedious process, and high difficulty in conventional manual inspections. We propose a novel method for calculating the tilt angle using point cloud data obtained from unmanned aircraft. Our method starts by acquiring the point cloud data of power tower by unmanned aircraft, followed by the extraction of their major structure, considering both statistical characteristics and structural components. The centerline of the power tower is then computed and used in conjunction with the plumb line of the ground to determine the tilt angle. To verify the effectiveness of our method, experiments are conducted by applying it to four power towers in different locations. The accuracy of the calculated tilt angles is analyzed through numerous simulations and influential factor analysis. The results suggest that our method achieves a high accuracy of 0.017 4° on average, demonstrating the effectiveness and reliability for use in conventional tower inspection.
