Embodiment Construction
[0032] A power line anomaly detection method based on images captured by a UAV will be further described in detail below in conjunction with the embodiments of the accompanying drawings.
[0033] refer to figure 1 and figure 2 , a kind of transmission line anomaly detection method based on unmanned aerial vehicle photographing image of the present invention, comprises the following steps:
[0034] 1) Convert the RGB color image obtained by mixing the three primary colors of R (red), G (green), and B (blue) in proportion to a grayscale image. Take the red, green and blue scores of each pixel in the image in turn, convert them into gray values according to the following formula, and then assign the new gray values to the corresponding positions of the image;
[0035] Gray=0.299×R+0.587×G+0.114×B.
[0036] 2) In order to prevent excessive optical correction of the image, a transition interval is set according to the gray value of the image, the original information of the...
