To study the technical method of three-dimensional imaging based on column lens grating produced by professional image processing software using the principle of grating stereo imaging. The stereoscopic printing images in manuscript were placed in layers in the foreground order using the Photoshop CS 5 image processing software, then imported into the 3D MAGIC V2 professional 3D software to create raster images through a series of processing, in the end, the cylindrical lens grating and raster images were precisely aligned and piped, and grating stereo images were formed. An image with a good stereoscopic vision effect was obtained after the treatment of professional computer software. Making cylindrical lens grating three-dimensional map using the professional image processing software was a simple and practical method. The resulting stereogram effect was strong, entertaining and had a broad application prospect.
