Problems solved by technology

At present, domestic fastener thread detection is still at the stage of manual visual inspection, which is not only inefficient, but also prone to false detection and missed detection.
With the transformation of the manufacturing industry towards high-speed, high-volume, and automated models, the traditional fastener thread detection technology has been unable to meet the needs of modern industrial production. It is urgent to develop an efficient and low-cost fastener thread detection technology.

Abstract

The invention belongs to the field of thread detection technology researching, and discloses a single-camera wide-field-of-view visual thread detection device and a detection method thereof. The single-camera wide-field-of-view visual thread detection device comprises a single-camera wide-field-of-view visual sensor, a carrying platform, an image acquiring card and a computer, wherein the single-camera wide-field-of-view visual sensor comprises a camera, an upper reflecting mirror group, a lower reflecting mirror group, a metal rod and an LED (Light-Emitting Diode) annular light source; a threaded fastener to be detected is vertically arranged under the single-camera wide-field-of-view visual sensor and at the central position of the carrying platform; the image acquiring card is arranged in the computer, and is connected with the camera in the single-camera wide-field-of-view visual sensor through a cable; the computer is used for analyzing images acquired by the image acquiring card to realize thread defect detection of the fastener.

Description

technical field [0001] The invention belongs to the research field of thread detection technology, and in particular relates to a single-camera wide-field visual thread detection device and a detection method thereof. Background technique [0002] As a common mechanical part, fasteners are widely used in manufacturing industries such as machinery, automobiles, and aircraft. Fastener thread defects will directly affect its performance and lead to various safety hazards. Individuals with defects must be removed before they are put into use to avoid unforeseen consequences. At present, domestic fastener thread detection is still in the stage of manual visual inspection, which is not only inefficient, but also prone to false detection and missed detection. With the transformation of the manufacturing industry towards high-speed, large-volume, and automated models, the traditional fastener thread detection technology has been unable to meet the needs of modern industrial product...
