Internal thread defect detection method, device , system, apparatus and medium

Abstract

The invention discloses an internal thread defect detection method, device and system, a computer apparatus and a medium. The method comprises the steps that an internal thread image, sent by an imageacquisition module, of a target object is acquired firstly, wherein the internal thread image is an image which is acquired by the image acquisition module through a prism component and an image acquisition component and comprises complete internal thread information of the target object, and the efficiency and precision of internal thread image acquisition can be guaranteed; further, the internal thread image is identified through a preset defect detection model, and defect detection information of the target object is obtained. And the efficiency and the accuracy of defect identification inthe internal thread image are ensured.

Description

technical field

[0001] The invention relates to the field of automation, and in particular, to a method, device, system, equipment and medium for detecting internal thread defects. Background technique

[0002] With the continuous development of science and technology, the quality requirements for many components are getting higher and higher. There are internal threads in many parts, and the quality of the internal threads will have a great impact on the realization of the whole machine or function. For example, the voice coil motor (VCM) of a smartphone camera is an important part of the mobile phone and plays a crucial role in adjusting the focal length of the camera. Among them, if the inner thread of the voice coil motor is defective, its performance will be directly affected. Therefore, before the voice coil motor is put into use, it is necessary to check out the individuals with appearance defects, so as to avoid the low performance of the produced mobile phone. [...
