Stereoscopic display technology has a high sense of presence and can bring unparalleled stereoscopic enjoyment to the audience, which requires stereoscopic glasses, helmet display and other auxiliary visual tools in that greatly limits its application. Auto-stereoscopic display technology (especially based on lenticular lens ) enables the audience to feel the visual impact brought by stereoscopic images freely and clearly with the naked eye in multiple positions within the larger perspective, thus greatly promoting the development and application of stereoscopic display technology. In this paper, an integrated imaging technique based on lenticular lens (88 inches) and projection equipment is introduced. The parameters of lenticular lens grating are calculated firstly, then, we use the 3Ds Max software to acquire the parallax images of the object, integrating all the parallax image pixels together to obtain an image with parallax by using Matlab program. The integrated parallax image is matched by the optical transmission characteristics of the lenticular lens. Experiment show that, the integrated imaging technique based on lenticular lens (88 inches) and projection equipment can display a good stereo image and realize super large-size, true color, dynamic and smooth parallax display. A 3D display by using a large lenticular lens and a projector is achieved in this paper.
