Abstract

Theoretical calculation shows that while the seam width deviation of two holographic lens sheets or edge line deviation between two holographic lens is less than 0. 1 mm

which can meet demand of naked eye 3D LED display system based on holographic lens technology for stitching of holographic lens sheet. The process of largesize holographic lens sheet stitched by several small-size lens sheets is studied

combined with method of stitching based on projecting stripes

automation stitching scheme based on machine vision is proposed. Analyze variation rule of bright stripes spacings in process of relative position change of two holographic lens sheets

system operation program based on Lab VIEW is compiled. According to theoretical analysis and system design

closed-loop control experimental platform is set up. Experimental results show that using this system can move two holographic lens sheets the precise position high-efficiently and the relative position deviations of the holographic lens sheets is less than 0. 1mm

which meets demand of theoretical computation. This system method can be applied in the small scale lens sheet auto-stitching system.
