Abstract

The invention discloses a machine-vision-based raster stereo image flat printer for realizing stereo printing on a raster plate matrix. The printer comprises a printing system, a visual sense measuring system and an error correction processing system, wherein the visual sense measuring system is used for obtaining the image of a raster plate on the printing system and detecting a position and an angle; the error correction processing system calculates the position deviation of the raster plate and the printed image according to the position and the angle and controls the printing system to perform corresponding position error correction according to the deviation so that a stereo image can be obtained by printing at an accurate position. By using the printer and the method provided by the invention, the problems of low printing precision, complicated operation, difficult automation realization and the like in a conventional raster stereo image printing process can be overcome, a method of machine visual sense measuring positioning and mechanical and visual sense auxiliary error correction is adopted so that the stereo image printing based on the raster plate can be realized, the material adaptability can be improved, the operation is convenient, and the printing precision is high.

Description

technical field [0001] The invention relates to a flatbed printer, in particular to a flatbed printer capable of automatically aligning grating plates and printing stereoscopic images. Background technique [0002] The grating stereoscopic image is generally synthesized by two or more images with horizontal parallax. After the grating is refracted, the audience can watch the stereoscopic image without wearing special glasses. Stereoscopic pictures can transfer human vision from two-dimensional space to three-dimensional space, so as to restore the depth of the scene on the three-dimensional picture to increase the realism of the picture. Stereoscopic image technology includes holographic stereoscopic image, grating image, and semi-cylindrical lens image processing technology. Among them, it is relatively easy to use a grating plate to generate a three-dimensional image, which mainly involves the principle of lens imaging, and is the most widely used three-dimensional image ...
