Airborne photoelectric measurement apparatus of dimensions and spacing of electric transmission line and target, and method thereof

Abstract

The invention relates to an airborne photoelectric measurement apparatus of the dimensions and the spacing of an electric transmission line and a target, and a method thereof, and belongs to the electrical line detection field. The apparatus comprises an unmanned plane, a photoelectric stabilized gondola and a ground system; and the photoelectric stabilized gondola is connected to the unmanned plane, and the ground system controls the unmanned plane and the photoelectric stabilized gondola through radio communication. The method comprises the steps of flight on a line, adjustment motion, measurement, acquisition and transmission. The apparatus has the advantages of flexible motion, simple operation and economy, and the exploitation of the airborne photoelectric automatic measurement apparatus of the remote target dimension and the spacing of the electric transmission line and the target through the combination of the photoelectric stabilized gondola and the design of a laser measurement system in the gondola greatly reduces the line inspection labor intensity of a worker, reduces the running and maintenance costs of electric transmission, improves the inspection work quality and the technological level of scientific management, enhances the electric production automation comprehensive capability, creates high economic and social benefits, and is of great significance.

Description

technical field [0001] The invention belongs to the field of power line inspection and detection, and in particular relates to an airborne photoelectric measuring device and a method thereof for the size and distance between a power transmission line and a target. Background technique [0002] Electricity is the economic lifeline of our country, and the safe operation of infrastructure such as power transmission lines as a carrier of electricity plays a vital role in the normal development of the national economy. Power transmission lines are widely distributed and long, and many of them are distributed in barren and inhabited mountains. The natural environment such as terrain, geology, and meteorology in each area is relatively complex. In order to ensure the normal operation of transmission lines, regular and effective inspections of transmission lines must be carried out. For a long time, most of the work of operation, maintenance and repair of transmission lines in my co...

Problems solved by technology

However, due to the complexity and irregularity of trees, traditional aerial photogrammetry methods cannot obtain accurate tree elevations. At present, aerial lidar systems are mainly used to detect the heights of lines and trees, but there are two important problems. One is The cost is very expensive, and the second is that it is easy to miss relatively small dangerous targets

The above-mentioned equipment in foreign countries all use civilian technology, and the image measurement quality is not high during the transmission lin
