Embodiment Construction

[0033] The specific embodiments of the present invention are further described below with reference to the accompanying drawings, but the present invention is not limited.

[0034] figure 1 A clip defect detection method based on deep learning and machine vision fusion is shown, including the following steps:

[0035] (1) Image acquisition of the clip workpiece;

[0036] (2) To detect tooth defects on the clips based on the deep learning method;

[0037] (3) Detection of clip size defects based on machine vision;

[0038] (4) Finally, the clip defect detection results are obtained by statistics.

[0039] In step (1), the red bowl lamp is used for illumination, and the dimensional vision MV-VD130 industrial digital camera is used to take pictures and collect, and the image resolution is 1280*1024.

[0040] In step (2), the concrete steps are as follows:

[0041] 1) Establish a clip tooth shape defect data set, which includes flat tooth, rotten tooth, heavy tooth, light pla...

Abstract

The invention discloses a clip defect detection method based on depth learning and machine vision fusion. The invention relates to the field of automatic detection technology, which aims at overcomingthe problem of low detection accuracy caused by the manual extraction of features in the clip quality detection method based on machine vision. The method comprises the following steps: (1) image acquisition of the clip workpiece; (2) tooth defect detection of the clip through depth learning; (3) size defect detection based on the method of machine vision; (4) obtaining of the results of defect detection through statistics. The technical scheme of the invention is simple to realize and can effectively improve the detection accuracy rate of the clip defects.

Description

technical field [0001] The invention relates to the technical field of automatic detection, in particular to a clip defect detection method based on deep learning and machine vision fusion. Background technique [0002] With the development of prestressed anchorage technology, anchorage clips (referred to as clips) account for an increasing proportion of prestressed anchorage engineering, and are widely used in the construction of various bridges and roads. Damage directly affects the safety of prestressed structures. If workpieces with quality defects flow into the market, it may lead to safety accidents in buildings in severe cases, which will greatly damage social security and people's property, and also bring great economic losses to production enterprises. Liability Risk. [0003] Therefore, the detection of clip quality defects is a very important link. At present, manual detection is mostly used in the production line, which has low efficiency and high cost. In view...
