Embodiment 1

[0073] As a preferred embodiment, the video enhancement system 6 enhancement methods provided by the present invention are as follows:

[0074] (1) Obtain the frame-level noise weight of the current frame according to the current frame of the video image and the corresponding pixels of the previous frame through the video enhancement program.

[0075] (2) Obtain the noise weight and DC component corresponding to each pixel according to each pixel of the current frame and the preset first window.

[0076] (3) Obtain the high-frequency coefficient group corresponding to the current frame from the pixels of the current frame according to a preset sorting strategy.

[0077] (4) Acquiring an image enhancement gain value according to the frame-level noise weight of the current frame and the high-frequency coefficient group.

[0078] (5) Obtain a high-frequency value corresponding to each pixel according to the image enhancement gain value, each pixel of the current frame, and the D...

Embodiment 2

[0090] As a preferred embodiment, the line fault early warning system 7 early warning methods provided by the present invention are as follows:

[0091] 1) Collect and report the hidden dangers and breakout information of the line through the line monitoring equipment.

[0092] 2) Combining the hidden dangers and breakout information of the line, the historical data of hidden dangers and the historical breakout data, big data mining algorithms are used to mine data, analyze the probability of hidden dangers, and output the analysis results as early warning information.

Abstract

The invention belongs to the technical field of wire peeling. The invention discloses a wire peeling device based on an electric power system, an image processing method and a storage medium. The wirepeeling device based on the electric power system comprises a peeling video acquisition system, a main control system, a cleaning system, a cutting system, a cutting positioning system, a video enhancement system, a line fault early warning system and a display system. According to the invention, image enhancement is carried out through the video enhancement system based on the noise levels of different granularities of the video frames and the detail degrees of the video frames, so that the amplitude of image enhancement can be adaptively controlled, the enhancement of the noise part can beavoided, and the output video image has relatively high definition; meanwhile, statistical analysis is conducted on historical external damage data through the line fault early warning system, an external damage thermodynamic diagram is formed, hidden danger prediction can be achieved along with accumulation of external damage and hidden danger data and based on big data analysis and mining, and aresult is displayed in an early warning mode.

Description

technical field [0001] The invention belongs to the technical field of wire peeling, and in particular relates to a wire peeling device based on an electric power system, an image processing method and a storage medium. Background technique [0002] A wire is a planar control graphic in the form of a polyline formed by connecting a series of measurement control points in adjacent order. It consists of a series of wire elements: wire point, which is the known point and the point to be determined on the wire; wire edge, which is the polyline edge connecting the wire points; wire angle, the horizontal angle between the wire edges. The wire angle connected to a known direction is called the connection angle (also known as the orientation angle). The wire angle is called left angle or right angle respectively according to its position on the left or right side of the wire advancing direction, and the left angle is specified as positive and the right angle is negative; the differ...
