The line glance localization UV printing system of claim 2, further comprising an image print management module for constructing an image print management platform based on a micro-service technology and applying to image print management; the image printing management module comprises an image printing management platform setting unit and an image printing management unit;

The image printing management platform setting unit is used for constructing an image printing management platform based on the visual controller and the cloud platform, setting image data storage micro-service and image data access micro-service based on the micro-service architecture, setting a plurality of micro-service user terminals, and setting printing use permission of the micro-service user terminals for target images;

and the image printing management unit is used for managing the printing use of the micro-service user side on the target image based on the image printing management platform.

9. An image processing method, comprising:

s1, configuring an image acquisition device, an image processing device and a visual positioning UV printing device;

S2, acquiring an original image of a target to be printed by using image acquisition equipment;

presetting a reference image based on a processor; acquiring a line image and a frame image in a reference image, setting a first matching data pair of the line image and a line trigger signal, and setting a second matching data pair of the frame image and the frame trigger signal; acquiring a row trigger signal and a frame trigger signal for image acquisition based on the first matching data pair and the second matching data pair;

based on a processor, a line trigger signal and a frame trigger signal are sent to a line scanning camera, and the line scanning camera acquires images to obtain a first original image of a target to be printed;

Acquiring a line image and a frame image of a first original image, and comparing pixel point number values of the line image and the frame image of the first original image with pixel point number values of the line image and the frame image of a reference image to acquire a plurality of line image pixel point number difference values and frame image pixel point number difference values; if the difference value of the number of the pixels of the line image or the difference value of the number of the pixels of the frame image is larger than a preset difference value threshold, adjusting the transmitting frequency amplitude of the line trigger signal and the frame trigger signal according to the preset adjusting frequency amplitude, generating a first line trigger signal and a first frame trigger signal, transmitting the first line trigger signal and the first frame trigger signal to a line scanning camera, acquiring the image again, comparing the difference value of the number of the pixels again, and generating an original image of a target to be printed when the difference value of the number of the pixels of the line image and the difference value of the number of the pixels of the frame image are smaller than the preset difference value threshold;

s3, processing the original image by using image processing equipment to generate image data to be printed;

and S4, printing and generating a target image of the target to be printed according to the image data to be printed by using the visual positioning UV printing equipment.
