Example Embodiment

[0020] The camera control device and the control method of the printing plate quality inspection instrument provided by the present invention are used for the detection of the sample banknote printing plate. After the sample banknote printing plate is placed on the measuring platform 6, it needs to take a picture. The camera is in the camera. Under the control of the control device, the sample banknote printing plate is photographed at regular intervals, and then subsequent operations are performed.

[0021] Such as Figure 1-4 As shown, the camera control device of the printing plate quality inspection instrument includes a control unit, a control terminal, a camera motion control module, and a camera position detection module.

[0022] The control unit is used to control the operation of the camera control device, and includes a computer 11 with a built-in multi-axis control card 7 and a motion controller 1. The multi-axis control card 7 is built in the host of the computer 11. ...

Abstract

The invention discloses a camera control device and a camera control method for a printing plate quality inspection instrument. The camera control device comprises a control unit, a control terminal, a camera motion control module and a camera position detection module. According to the camera control device and the camera control method disclosed by the invention, a double trigger photographing technology based on real-time position photographing of a camera is adopted, photographing parameters and motion parameters of the camera can be adjusted dynamically according to the plate texture content, correct photographing parameters and motion parameters are calculated through the first time of photographing under the condition that the printing plate is not radiated by a light source continuously, and photographing is carried out on the printing plate according to the correct parameters when the camera is triggered the next time, thereby realizing dynamic parameter photographing for the overall layout of the printing plate without influencing the printing plate to be inspected, and being good in photographing effect.

Description

technical field [0001] The invention belongs to the technical field of printing plate quality inspection instruments, and in particular relates to a camera control device and a control method of a printing plate quality inspection instrument. Background technique [0002] After the production of large-sized printing plate workpieces such as banknote printing plates is completed, it is necessary to use a printing plate quality inspection instrument to check the quality of the printing plate. During the inspection, the printing plate is first fixed on the workbench, and then the camera movement is controlled by the camera control device, so that the camera performs a two-dimensional scanning movement relative to the workbench along the X and Y axes; during the movement, the camera is fixed every other The printing plate can be photographed at a distance of 1000° to realize the overall photographing and measurement of the workpiece. Therefore, the image measurement system for l...
