Quality Assessment of High-Voltage Transmission Lines Based on Multi-modal Data Fusion

Abstract

Quality assessment is one of the essential aspects of the acceptance of transmission line project completion. To resolve the challenge of efficiency and accuracy, we presents a multi-modal data fusion approach established on two new technology, which are the 3D laser point cloud technology and the BIM technology. The scanned 3D laser point cloud data of transmission lines are firstly filtered and classified to build the laser point cloud model; The BIM based 3D model of transmission lines are then converted to the BIM point cloud model; the laser point cloud model and the BIM point cloud model are registered through application of both a coarse registration and a fine registration; Differences between the laser and the BIM point cloud models are assessed for the acceptance of transmission line project. Validation results showed that the multi-modal fusion algorithm had highly satisfactory performance.
