This application discloses a method and device for extracting fire points of power transmission lines from massive satellite image data. By acquiring satellite images within a preset time length, the satellite images are gridded and data packets are sent to different GPUs respectively. The grid data package is processed, and the grid data package is matched with the GIS coordinate model for projection coordinates, and the matching grid data package is extracted to extract the fire point position, and the unmatched grid data package does not need to be processed. The useless data processing process is reduced, and finally the fire point processing data of each GPU is merged, combined with the GIS of the transmission line tower to obtain the data of the fire point near the transmission line and the fire point alarm, which improves the satellite image data of the transmission line fire point The processing efficiency solves the technical problems that the existing polar-orbiting meteorological satellite detects the mountain fire on the transmission line, and the satellite image data processing efficiency of the fire point of the transmission line is low, which affects the fire prevention work of the transmission line.
Description
technical field [0001] The present application relates to the technical field of transmission line mountain fires, in particular to a method and device for extracting transmission line fire points from mass satellite image data. Background technique [0002] In recent years, the frequency of wildfires near transmission lines has been increasing year by year. Fires on transmission lines have become a major hidden danger affecting the safe operation of smart grids. In severe cases, they may even cause grid collapse and large-scale power outages. [0003] At present, polar-orbiting meteorological satellites are used to detect wildfires on transmission lines. The spatial resolution of sub-satellite points of high-resolution polar-orbiting meteorological satellites reaches 400m, and a single satellite data picture is nearly 10G. The amount of data is huge. After the reception is completed, the mass data is quickly viewed and projected. However, the useless data in the mass data a...
