Defect detection method and system for liquid leakage sensing assembly production

The invention relates to the field of image data processing, in particular to a defect detection method and system for liquid leakage sensing assembly production, and the method comprises the steps: collecting a frame image in a video stream of a liquid leakage sensor, carrying out the preprocessing, setting a label, generating a sample data set, training a model through the sample data set, and obtaining a label image; calculating a difference value of the pixel value matrixes of two adjacent frames of label images to obtain a difference value matrix, and clustering the difference value matrix as a glue overflow matrix to obtain a cluster corresponding to a glue overflow area; calculating the ratio of the number of pixel points in the glue overflow area to the frequency time of collecting the image frame to obtain the expansion speed of the glue overflow area; constructing a glue overflow vector, and obtaining a gluing imbalance evaluation value according to the glue overflow vector and the expansion speed o
