Description
Summary:The paper presents a new solution used to detect the Corona discharge, based on the data fusion from two CCD (charge coupled device) image sensors used in UV and visible spectrum. The potential of the method comes from the fact that the Corona discharge is caused by a very intense electrical field, which ionizes the surrounding air and generates a discharge light, detectable by both CCD sensors, in UV and visible spectrum. The image of the Corona discharge pass from the same lens, and using a beam splitter is directed to the two CCD sensors. Further, the UV and visible images are processed, the fusion of the obtained results leading to the exact positioning of the Corona discharge in the scanned area of interest. The optical detection system is integrated in an Unmanned Aerial Vehicle (UAV), and, together with the telemetry data (global coordinates, speed, attitude angles, ... ), transmits to the Ground Control Station (GCS) the data acquired by the sensors installed on board; the most important are the video streams in various spectra, which depend by the specifics of each developed mission. The data are real-time transferred to a Ground Mission Analysis System (GMAS) which realize the processing. In the paper are successively exposed: the operational concept of the Corona discharge detection by using CCD image sensors, the architecture of the developed optical detection system, and the mechanism used in the image data processing for location and evaluation of Corona discharge.
