Powder leakage detection method and device for flexible connection device, electronic equipment and storage medium

The invention provides a powder leakage detection method and device for a flexible connection device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a gray image corresponding to the flexible connection device, and determining an image segmentation threshold value based on the pixel point features of the gray image; based on the image segmentation threshold, segmenting the grayscale image to distinguish a foreground pulverized coal object from a background of the grayscale image, and obtaining a target segmented image; based on the grayscale image, extracting an edge contour image of pulverized coal accumulation; and obtaining a soft connection powder leakage detection result based on the target segmentation image and the edge contour image. According to the powder leakage detection method and device for the flexible connection device, the electronic equipment and the storage medium provided by the invention, the threshold segmentation algorithm and the edge extractio
