Embodiment approach

[0060] As an implementation manner, the image acquisition unit includes a code image imaging module and a light emitting module;

[0061] The light emitting module is used to illuminate the collection area and adjust the brightness of the code image collected by the code image imaging module.

[0062] Such as figure 2 As shown, the embodiment of the present application also provides an image sequence matching method for visual inspection equipment, the method is applied to the above system, and the method includes the following steps:

[0063] When it is detected that the object under test is transferred to the initial position, the control card generates a calibration information of the object under test;

[0064] When it is detected that the object under test is transmitted to the detection position, the control card sends a frame trigger signal to the image acquisition unit, and records the first time stamp information corresponding to the sending time;

[0065] After re...

Abstract

The invention provides an image sequence matching system and method for visual inspection equipment, the system comprises a control card, and an image acquisition unit and an upper computer which are connected with the control card, the system is configured to execute the following steps: when it is detected that a to-be-detected object is conveyed to a starting position, the control card generates calibration information of the to-be-detected object; when it is detected that the to-be-detected object is conveyed to a detection position, the control card sends a frame trigger signal to the image acquisition unit and records first timestamp information corresponding to the sending moment, and after the image acquisition unit receives the frame trigger signal, the image acquisition unit acquires an image of the to-be-detected object and sends second timestamp information corresponding to the image acquisition moment to the control card; the control card sends the first timestamp information and the second timestamp information to an upper computer; and the upper computer compares the first timestamp information with the second timestamp information, and if the first timestamp information is consistent with the second timestamp information, the calibration information of the object to be measured is matched and bound with the image information.

Description

technical field [0001] The present application relates to the technical field of industrial vision, in particular to an image sequence matching system and method for visual inspection equipment. Background technique [0002] A large number of printed products are used in the industrial production process, such as packaging boxes of industrial products, label paper, etc. These printed products usually need to be produced by printing, laminating, die-cutting and cutting. Any printed product, no matter it is printed on a single sheet or on a roll, always needs or basically needs to be cut into a single sheet for shipment in the end, and an end point inspection is required before shipment. Especially in the part of color box printing and packaging, after die-cutting, there will be waste products generated in many processes and processes, and the quality inspection of single-sheet products must be carried out. [0003] In the traditional technology, multiple imaging stations are...
