The invention relates to the technical field of cable detection, and discloses a cable intermediate joint construction defect detection method, system and device based on image recognition, and the method comprises the steps: obtaining a plurality of images for splicing processing; preprocessing the spliced image, and enhancing the edge of image information; detecting the gradient and direction of the cable main insulation intermediate joint image, setting double thresholds according to otsu, and segmenting image information into edge pixel points and non-edge pixel points; and carrying out isolation judgment on the edge pixel points, removing pseudo edge pixel points in the edge pixel points to obtain complete edge information, and finally detecting the construction defects of the intermediate joint according to the obtained complete edge information. Compared with the prior art, the method can effectively prevent the occurrence of joint faults of the power system, improves the stability of the power system,
