Abstract

A detecting device includes an actuating unit for driving a transparent grating structure, a light source for emitting light to the transparent grating structure driven by the actuating unit, a light sensor for sensing the light emitted from the light source as the transparent grating structure is moved to different positions relative to the light source so as to generate a corresponding optical intensity signal, a transforming circuit coupled to the light sensor for transforming the optical intensity signal into a transforming signal, and a processing unit coupled to the transforming circuit for determining a position of the transparent grating structure according to the transforming signal transmitted from the transforming circuit.

Description

technical field [0001] The invention relates to a detection device and a detection method for detecting a light-transmitting grating structure, in particular to a detection device and a detection method for detecting the light-transmitting grating structure by using light sensing intensity. Background technique [0002] In the traditional 3D image production process, since the grating plate is made of light-transmitting materials, it is difficult for general devices to detect its position and locate it. Therefore, the common method is to print the 3D image on opaque photo paper or cards first. On the base material, the light-transmitting grating plate is pasted on the base material so as to facilitate detection and positioning and produce a stereoscopic effect. The three-dimensional image is an interlaced image produced in accordance with the grating plate style (parameters such as the width and density of each grating on the grating plate), and the position of each grating ...
