A linear image correction method, system and related equipment for laser imaging

Abstract

Embodiments of the present invention provide a linear image correction method, system and related equipment for laser imaging, which are used to solve the problem of geometric distortion of linear images during the laser imaging process. In the embodiment of the present invention, the image correction system takes the direction opposite to the offset of the target line segment as the correction direction, and uses the offset of the target line segment in the X-axis direction as the correction distance to move the pixel row where the target line segment is located to generate a corrected image, This enables the laser imaging device to offset the offset of the image in the X-axis direction during the exposure imaging process. At the same time, in the image after correction, the correction distance of the pixels on the same target line segment is the same, the target line segment after correction is still perpendicular to the X-axis direction, and the edge of the vertical line segment does not protrude from the edge of a similar oblique line, which can effectively avoid the laser exposure process The appearance of sawtooth similar to the edge of the slash image ensures the straightness of the linear image after exposure imaging.

Description

technical field [0001] The invention relates to the technical field of laser imaging, in particular to a linear image correction method, system and related equipment for laser imaging. Background technique [0002] The principle of laser imaging is to control the photosensitive coating on the exposed surface of the laser to perform image exposure, and to generate a preset image after development. Compared with traditional processes, laser imaging technology reduces process complexity and saves production costs, and is widely used in screen printing plate making, PCB manufacturing and other fields. [0003] The applicant has noticed that due to factors such as the installation error of the laser, the inconsistency of the spot shift of the laser on the exposure surface, the deviation of the scanning displacement, etc., during the laser exposure process, the linear image after development on the photoresist coating is often caused. The template image is geometrically distorted...
