Abstract:Stereoscopic paintings are widely used in outdoor advertisements, giant posters, and stage backgrounds. Current stereoscopic paintings have some defects, such as a few viewpoints, poor stereoscopic perception, and serious crosstalk. This paper describes a super multi-view large stereoscopic painting design. The formulas are derived based on the vision principle of human eyes and the optical transmission characteristics of a cylindrical lens to calculate the thickness of the cylindrical lens, the radius of curvature, and the grating pitch. The viewing distance is 6 m and the viewing area width is 3 m with 59 viewpoints. The viewpoint distribution is simulated by the optical design software called LightTools. The viewpoint width is 50 mm, which is less than the distance between normal adult pupils. The circular lenticular lens array is designed to reduce the crosstalk between viewpoints with crosstalk of 11.7%-15.8%. The simulation results are verified by experiments which show that the super multi-view large stereoscopic painting design meets the requirements for auto-stereoscopic viewing.
