Problems solved by technology
[0002] With the development of the economy, environmental problems are particularly prominent. The air pollution in many places is relatively serious, and the intensification of air pollution in non-periodic areas has brought new challenges to the early warning and prevention of pollution accidents on the external insulation of power transmission and transformation equipment.
Although the traditional ESDD online monitoring technology has a relatively good monitoring of insulator pollution, it can only achieve better results at the monitoring point
However, it is a very heavy workload for traditional monitoring methods to assess the pollution level of a large area, and in remote areas, due to factors such as complex terrain, it is difficult to obtain data, and the risk of field operations is relatively high

Description
technical field [0001] The present application relates to the field of remote sensing technology, in particular to a large-area high-precision insulator contamination distribution evaluation method. Background technique [0002] With the development of the economy, environmental problems are becoming more prominent. The air pollution in many places is relatively serious, and the aggravation of air pollution in non-periodical areas has brought new challenges to the early warning and prevention of pollution accidents on the external insulation of power transmission and transformation equipment. Although the traditional ESDD online monitoring technology has a relatively good monitoring of insulator pollution, it can only achieve better results at the monitoring point. However, the assessment of pollution level in a large area is a very heavy workload for traditional monitoring methods, and in more remote areas, due to factors such as complex terrain, it is difficult to obtain d...
