Problems solved by technology

[0005] The purpose of the present invention is to provide an automatic detection system for transparent bottles. The technical problems to be solved are the problems in the prior art that the shooting range of the lens is small, the imaging resolution is low, the operation process of the image processing is complicated, and the noise interference is serious. The present invention greatly reduces the calculation process and improves the accuracy of detection through the image filtering method of image segmentation, image denoising and adaptive Butterworth high-pass filter. 20 Sb 15 Se 65 Combining glass lenses with zinc selenide lenses and zinc sulfide lenses not only improves the viewing angle of the lens, increases the shooting range, but also greatly increases the Abbe number, reduces the degree of dispersion, and then improves the resolution and quality of imaging

Embodiment 1

[0025] An automatic detection system for transparent bottles, specifically comprising the following:

[0026] Optical lighting system: including a light source and a light source controller, providing uniform and stable lighting for the image acquisition system, making the surface features of the transparent bottle to be tested visible; the light source is a ring light source, providing different angles of illumination, highlighting the three-dimensional information of the transparent bottle, and solving Diagonally illuminated shadowing issues.

[0027] Image acquisition system: including industrial cameras, lenses and image acquisition cards, which mainly collect images on the surface of transparent bottles, and output video signals from the system unit for processing by the image processing unit; industrial cameras are CCD cameras, which convert optical images into corresponding Digital signal, and the digital signal is transmitted from the interface between the industrial c...

Embodiment 2-11

[0035] In the image acquisition system, since the lens is the starting point for the information collection and transmission of the measured object in the entire visual system, its quality directly affects the accuracy of the measured transparent bottle information contained in the final image. The lens is an important part of the lens. Its performance directly affects the quality of the lens. In order to form the optical image of the target on the surface of the CCD sensor, the CCD camera can collect clear and sharp images, reduce the degree of dispersion, improve the resolution of the imaging and its Quality, the used lens of the present invention is made of 6 lenses, and the first three lenses are Ge 20 Sb 15 Se 65 Glass, zinc selenide and zinc sulfide, the focal power is negative, positive and positive respectively, and the last three lenses are zinc selenide, zinc sulfide and Ge 20 Sb 15 Se 65 Glass, its focal power is negative, negative, positive, respectively, where...

Abstract

The invention discloses an automatic detection system for a transparent bottle. The automatic detection system comprises the followings: an optical illumination system providing uniform illumination for an image acquisition system, the image acquisition system collecting a surface image of the transparent bottle and outputting a video signal from a system unit for processing by an image processingunit; and an image processing software system segmenting and positioning a defect area, detecting and judging the transparent bottle, and sending a removal signal for an unqualified product. The automatic detection system not only improves the view angle of a lens, increases a shooting range and improves imaging resolution, but also reduces a calculation process through image segmentation, thereby greatly improving the accuracy and speed of detection.

Description

technical field [0001] The invention relates to a detection system, in particular to an automatic detection system for transparent bottles. Background technique [0002] With the progress of society and the development of science and technology, people's living standards have been improved, and the market demand for mineral water and beverages has gradually increased. There are also higher requirements for the quality of transparent bottles used in packaging mineral water and beverages. However, in high-speed In the process of filling liquid and capping transparent bottles, the phenomenon of loose cap and bottle body, crooked cap and low liquid level often occurs, which affects the appearance quality of the product and has a certain impact on product sales. For transparent bottles For possible defects, it is necessary to increase the inspection process during the processing of transparent bottles to prevent unqualified products from flowing to customers. [0003] At present...
