Abstract

The invention discloses a positioning method and device and a computer readable storage medium, and the method comprises the steps of carrying out the binarization processing of a specified image, andobtaining a binarized image which comprises a target object; determining a designated area in the binarized image according to prior information corresponding to the target object; and carrying out positioning processing on the designated area, and determining a target image corresponding to the target object, so that the effect of improving the stability in the appearance detection process is achieved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a positioning method, device and computer-readable storage medium. Background technique [0002] In the process of using machines to detect defects on product appearance, the determination of product positioning information by machines is a necessary part of defect detection. For example, in the process of using a machine to inspect the appearance of a screen for defects, the machine needs to determine the specific position information of the screen in the image. However, due to environmental factors such as placement, lighting changes, uneven brightness, and linear defects, and / or its own factors, the accuracy of the machine's determination of product positioning information is not high. Improving the accuracy of product positioning information is conducive to Improve the stability of the appearance inspection process. Contents of the invention [0003] Embo...
