Description

Technical field: [0001] The invention relates to a power inspection image recognition method, in particular to a multi-feature fusion-based visual object extraction method and system for transmission lines. Background technique: [0002] Smart grid is the trend and direction of power grid development, and smart substation is the substation link of smart grid, which is an important foundation and support for a strong smart grid. Due to the large number of high-voltage equipment in the power place of the substation and the complex environment, regular inspections are required to ensure power safety. At present, most substations still use manual inspections. With the continuous development of robot technology, more and more substations have begun to use inspections. Robot inspection and automation technology replace traditional manual work, which can reduce labor costs. [0003] The use of drones for inspections of transmission lines, although information collection is conveni...
