Embodiment Construction

[0038] Such as figure 1 As shown, the specific detection method is as follows:

[0039] In step S101, extract adjacent frame images from the video monitoring terminal or video recording (high-definition camera);

[0040] In step S102, according to the image input in step S101, image preprocessing is performed on the extracted adjacent frame images, firstly, the key areas related to the transmission lines in the images are detected, and then the images of the key areas are grayscaled to obtain the grayscale picture:

[0041]

[0042] in is the pixel coordinates in the image, , m is the image height, , n is the image width, The pixel coordinates are The pixel values ​​of the red, green, and blue channels of is the pixel coordinate the gray value of;

[0043] After the image is grayscaled, image smoothing is performed on the image in the key area, and noise is filtered, and the image smoothing adopts the method of median filtering.

[0044] In step S103, acc...

Abstract

A high-voltage line foreign matter invasion target detection method includes the steps that an adjacent-frame image is extracted from a video monitoring terminal or a video, the extracted adjacent-frame image is preprocessed, the movement characteristic of the adjacent-frame image is extracted, foreign matter or an invasion target is detected, the foreign matter invasion target is marked through a morphological method, the foreign matter or the invasion target is tracked, whether a power transmission line is affected or not is judged, and if yes, an alarm is given. Through the method, the foreign matter invasion target is fast and accurately detected, a high-voltage line is monitored, and an actual application requirement can be met.

Description

technical field [0001] The invention belongs to the field of power grids and electric power, and in particular relates to a method for detecting foreign matter intrusion targets on high-voltage lines. Background technique [0002] Electric power is an important basic industry of the national economy, and safe and stable power supply is the prerequisite for ensuring the rapid and stable development of the national economy. In the national grid, the environment of high-voltage transmission lines is very complex and vulnerable, so it is particularly important to ensure the safety of high-voltage transmission lines. The traditional video surveillance system needs to manually monitor the video, and the monitoring performance is restricted by the physiological factors of the monitoring personnel themselves. With the rapid growth of the scale of high-voltage transmission lines in my country, the power sector has undertaken more and more high-voltage line inspections and maintenanc...
