Abstract
In this paper, a method integrating image processing and signal frequency is used to estimate relative misalignment of micro-structure the Double-sided Lenticular Lens Films (LLF). The pitch of the convex on each side of the LLF is 900μm. The main steps of this research consist of image denoising, edge detection and establishment of the misalignment v.s. image magnitude relation. A Butterworth low-pass filter is used to eliminate the noise due to debrits on the polymer substrate. The images that are acquired from LLFs for different relative misalignment quantities are used to analyze the spectrum and get its relation between misalignment position and frequency energy distribution. The experiment shows the proposed method may distinguish between cases with different relative misalignment of microstructure on LLF with a resolution of 20μm.
