英文摘要	The embodiment of the invention discloses a line broken-strand detection method and a line broken-strand detection system; the method comprises the following steps: obtaining transmission line and peripheral images in a region, carrying out preprocessing operation on the transmission line and peripheral images, obtaining a grayscale image of the transmission line, extracting characteristic information in the grayscale image to obtain a distribution histogram of a binaryzation image, and judging a broken-strand interval of the line according to the distribution histogram to finish the line broken-strand detection. By taking a boundary of the transmission line as a benchmark to obtain the smooth grayscale image of the transmission line, constructing the binaryzation image with line strand distribution characteristics, and taking periodic characteristics of the distribution histogram of the binaryzation image as the standard to judge whether the line broken strand exists simply, reliably, efficiently and quickly, the method and the device disclosed by the invention replace a manner of artificial tower-climbing detection; the safety risk of the detection is reduced, the safety of detection personnel is guaranteed, and the accuracy of the transmission line broken-strand detection is further improved.
