Abstract

The invention provides an optical grating three-dimensional printing image synthetic method based on a binocular camera. The optical grating three-dimensional printing image synthetic method comprises the steps of using the binocular camera to shoot a scene so as to obtain a binocular image pair, wherein the binocular image pair comprises a left view and a right view; obtaining a binocular image depth map; constructing an image sequence, and taking the left view in the binocular image pair as a left-most sequence parallax image in the image sequence, and the right view in the binocular image pair as a right-most sequence parallax image in the image sequence to generate a plurality of sequence parallax images between the left view and the right view; compounding an optical grating three-dimensional image according to the image sequence; adjusting the resolution of the optical grating three-dimensional image, and outputting the optical grating three-dimensional image by taking a printer as output equipment and a lenticular grating as a carrier. The instant output with individuation and convenience of a three-dimensional printing product is realized, and a better three-dimensional effect can be observed by naked eyes for the optical grating three-dimensional image obtained by using the method.

Description

technical field [0001] The invention belongs to the technical field of printing, and in particular provides a binocular camera-based method for synthesizing grating stereoscopic printing images. The output grating stereoscopic image can be viewed with better stereoscopic effects with naked eyes. Background technique [0002] Existing grating stereo synthesis technologies are mainly divided into stereo synthesis based on a single image and stereo synthesis based on sequence parallax images. The three-dimensional composite technology based on a single image is mainly suitable for the production of three-dimensional printing products of a single original image. However, since a single image does not contain the three-dimensional information of the scene, it requires the operator to give the scene in the scene the corresponding three-dimensional information based on his own experience. Depth information, if the depth information is given incorrectly, it will greatly affect the q...
