Abstract

The invention discloses a power transmission line tree barrier felling planning method based on a hyperspectral remote sensing technology. A tree preparation type is detected by using non-contact hyperspectral, and tree identification can be conveniently carried out for a power transmission line with difficulty in manual inspection of a load terrain. A tree barrier felling planning strategy is putforward in a targeted mode, inaccurate visual inspection in manual inspection is avoided, the growth rates of different trees are considered in the established tree barrier felling planning model, and threats caused to a power transmission line by subsequent growth of trees which do not need to be felled temporarily are avoided. According to the method, the inspection frequency of the complex terrain manual inspection difficulty area is reduced, and the waste of manpower and material resources is reduced.

Description

technical field [0001] The invention belongs to the technical field of transmission line tree barrier prevention, and in particular relates to a transmission line tree barrier felling planning method based on hyperspectral remote sensing technology. Background technique [0002] In recent years, with the development of my country's forestry, the implementation of the policy of returning farmland to forests and the increasing requirements for environmental protection year by year, the existence of trees under the transmission line has become more and more serious hidden dangers to the transmission line; in recent years, trips and power outages caused by tree barriers in various provinces Accidents occur more than 100 times a year, seriously affecting the daily life of residents and causing a lot of economic losses. Therefore, timely and effective felling of trees under the transmission line is of great significance to maintain the safe operation of the transmission line. [0...
