Problems solved by technology
Because in order to strictly control product quality standards, the video inspection system adopts a special camera for image acquisition at each quality control point, and the video inspection system becomes more difficult with the increase of collection points. When the number of inspection points reaches a certain number, image acquisition will be caused Difficult, difficult to control and low detection efficiency in the detection process

Embodiment Construction
[0033] In order to have a clearer understanding of the technical features, objects and effects of the present invention, the specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
[0034] figure 1 and figure 2 A preferred embodiment of the device for online video detection of concave and convex patterns is shown.
[0035] The concave-convex pattern online video detection device can be used to detect the concave-convex pattern of the embossed printed matter in the process of producing the printed matter, and can detect whether the embossed position is accurate, further improving the qualified rate of the product and simplifying the printed matter embossing position detection testing procedures to improve the efficiency of testing. Among them, online refers to the production line of printed matter.

The present invention relates to a concave-convex pattern online video detection apparatus, which comprises an auxiliary tracking mark arranged on a printed product, an image collection device arranged above or on the side surface of a printed product production line and used for collecting the position of the auxiliary tracking mark, and a detection processing device electrically connected to theimage collection device and used for carrying out image comparison. With the concave-convex pattern online video detection apparatus, by arranging the detection processing device, the image information of the auxiliary tracking mark position collected by the image collection device is compared, such that whether the position of the concave-convex pattern on the printed is accurate can be rapidlyjudged so as to simplify the detection process, reduce the cost and improve the detection efficiency. The invention further relates to a concave-convex pattern online video detection method. With theconcave-convex pattern online video detection apparatus of the present invention, only the auxiliary tracking mark is required to be compared without the detection of the multiple quality control points, such that the detection process is simplified, the detection range is reduced, and the production efficiency is improved.
Description
technical field [0001] The invention relates to the field of concave-convex pattern detection, and more particularly, to an online video detection device for concave-convex patterns and a detection method thereof. Background technique [0002] In recent years, with the continuous improvement of the quality requirements of printed matter, in order to control the generation of defective printed matter to a minimum, it is strictly forbidden to circulate the defective printed matter, and it is required that the printing site must establish a strict production system and management system. Some printing companies, especially tobacco companies, have high quality requirements. Once quality problems occur, a large number of returns will be caused. In order to reduce the risk, most printing houses have adopted the method of manual full inspection of the printed matter. However, manual full inspection has its limitations, and not to mention the problem of visual fatigue, it is a very...
