Detection Method of Broken Position of Power Cable Based on UAV Photography
Because some power cables are in a bad environment,they are easy to be damaged and the operability of manual de-tection is insufficient,which leads to the problem of large error between the position detection results and the actual damaged position.Therefore,a detection method of damaged position of power cables based on UAV photography is proposed.We cali-brate the image coordinate system collected by UAV,and extract the effective position information of power cable damage.The color space segmentation technology is used to obtain the gray value of the image and correct the UAV photographic image.The gradient component algorithm of differential calculation is used to iteratively calculate the image processing results,com-plete the location analysis of the damaged point,and realize the detection of the damaged position of the power cable.Experi-ments show that the error between the position detection result and the actual damage position is the smallest comparing with the other methods,which effectively improves the detection accuracy of the damaged position of power cables.
