Camera control device and camera control method for printing plate quality inspection instrument

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...

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the motion control system of the image measuring instrument in the prior art has a bad shooting effect and affects the quality detection of the printing plate. The camera control device and its control method further provide a camera control device and its control method that can adjust the shooting position and angle in real time according to different workpieces, so that the subsequent images can be stitched seamlessly with high precision and ensure the normal quality inspection of printing plates
