This invention relates to the field of image processing technology, and in particular to an automated inspection method for the factory quality of liquid crystal screens based on image processing. The method acquires a grayscale image of the liquid crystal screen, divides the grayscale image into at least two window regions, merges the window regions according to their region type to obtain at least two target regions, marks the defect edge pixels in each target region, and further divides each target region based on the defect edge pixels to obtain multiple final divided regions. It then obtains the edge detection dual thresholds and region exposure coefficients of each final divided region and performs linear regression fitting to obtain the corresponding linear regression function. Using the linear regression function, it obtains adaptive edge detection dual thresholds for each final divided region, which are used to detect scratch defects on the liquid crystal screen. This achieves accurate calculation of adaptive edge detection thresholds for each region, effectively solving the problems of missed detections and false detections caused by traditional global thresholds.
