PHOTOGRAMMETRIC TECHNIQUES FOR POWER LINE RANGING

摘要

This paper presents a photogrammetric method for power line inspection, which is more informational, automatic and intelligent. The main task in the research is to extract the power line automatically during the flight, and then reconstruct the model of the electricity line through forward intersection. The objects below the power line are matched through VLL (Vertical Line Locus) algorithm. Finally, calculate the distance between the power line and the objects. Experiments were carried out, in which rapid data processing was performed during the flight, and the results proved that photogrammetric method is prior to the traditional method which is time-consuming and less efficient.
