The invention discloses a detection and high-definition imaging method for a flexible overhead line system dropper, and the method comprises the steps: obtaining a plurality of contact line images containing laser beams, carrying out the binarization preprocessing of light spot features in the contact line images, obtaining an image data set, carrying out the searching of BLOB blocks, and searching the white BLOB blocks on the images; judging whether the white BLOB meets the following two conditions at the same time: whether the form information of the white BLOB meets the threshold form interval; whether the position information of the white BLOB block accords with a threshold position interval is determined; all white BLOBs meeting the two conditions at the same time serve as sample input images, and whether dropper forms exist in the images or not is judged through a dichotomy model. The line laser of the specific wave band is emitted to the contact network, the high-speed camera is provided with the optic
