Embodiment

[0114] see figure 1 , the embodiment of the present invention discloses a method for detecting ice thickness based on image processing, the implementation steps of which are as follows:

[0115] Step 1: Use unmanned aerial vehicles to inspect the overhead lines of the field power grid, and take aerial photography and sampling of the transmission lines. Due to the complexity of the field environment, to ensure the quality of the pictures when taking aerial pictures of transmission lines, it is necessary to input the pictures of the transmission lines into the computer image processing system, filter the pictures, and delete the pictures with blurred shooting effects to avoid affecting the subsequent detection results. Filtered images are compressed to allow computers to process images faster.

[0116] Step 2: Map the aerial color image to the RGB color space for grayscale processing. Generally, in computer image processing, the default input image is processed in the RGB colo...

Abstract

The invention discloses a power transmission line icing thickness detection method based on image processing, and the method comprises the steps: employing a preprocessing method based on wavelet threshold denoising to eliminate the fuzzy interference and enhance the boundary contour details based on a power transmission line image obtained through unmanned plane inspection and aerial photography;detecting the boundary contour of the power transmission line region by using an improved Canny operator; and finally, on the basis of boundary contour detection, calculating the icing thickness by comparing the pixel widths of the line area images before and after icing and combining the actual power transmission line diameter. The method for detecting the icing thickness of the power transmission line is completed by a computer image processing technology, can be widely applied to power grid overhead line inspection, assists overhead line field inspection and maintenance operation, reducesthe labor intensity of inspection personnel, reduces dangerous operation in power grid operation, and avoids economic loss.

Description

technical field [0001] The invention belongs to the technical field of detection of ice coating thickness of power transmission lines, and in particular relates to a method for detecting the thickness of ice coating of power transmission lines based on image processing. Background technique [0002] With the continuous expansion of the scale of my country's power grid, the inspection of transmission lines has gradually turned to intelligence. As an important part of the power system, the transmission line is mainly responsible for the transmission of electric energy. Due to the complexity of the area where the transmission line passes, icing will form on the transmission line due to the influence of ambient temperature and humidity. When the icing is severe, it will cause insulator flashover, line galloping, tower collapse, and disconnection, etc., resulting in interruption of line transmission. Bring inconvenience to people's production and life, cause huge economic loss. ...
