Abstract

The invention discloses an optical fiber winding defect detection method and device based on ensemble learning. The method comprises the following steps of S1, acquiring an optical fiber winding image; S2, preprocessing the image acquired in the step S1; S3, carrying out defect detection on the image preprocessed in the S2 through a digital image processing model; S4, carrying out defect detection on the image preprocessed in the S2 through an SVM model; and S5, according to the digital image processing model and the SVM model, performing voting on defect detection results of the two models in the steps S3 and S4 according to corresponding weights by using a linear combination of set weight addition, judging whether voting results for a plurality of continuous pictures are not less than a set threshold score, and if so, judging that the optical fiber winding defect exists. The optical fiber winding defect detection device can reduce the misjudgment rate and the omission ratio, is suitable for optical fibers with various diameters, is more suitable for industrial environment production, and is high in adaptability.

Description

technical field

[0001] The invention relates to an optical fiber winding defect detection technology, in particular to an optical fiber winding defect detection method and device based on integrated learning. Background technique

[0002] Optical fiber guidance has been widely used in the military in recent years, and it is a key technology to deal with helicopters and tanks. Optical fiber guidance is the use of optical fiber sensing technology to realize real-time data transmission between ground consoles and air missiles. The principle of action is that there is a winding spindle-shaped optical fiber package at the tail of the missile connected to the launch console. The head of the missile is equipped with an infrared imaging reflection head or a low-light electronic camera. The picture is transmitted back to the ground in real time through optical fiber, and the shooter controls the missile according to the information transmitted back, and has the ability to launch, ob...
