Abstract
A distance measuring system includes a light source module, an image capturing device and a processing module. The light source module transmits a light beam having a speckle pattern to a first flat surface and a second flat surface, and an object. The image capturing device captures the image of the speckle pattern shown on the first and second flat surfaces, and captures the image of the speckle pattern shown on a surface of the object to produce first reference image information, second reference image information, and object image information. The processing module calculates a displacement vector of the speckle pattern according to the first and second reference image information. The processing module calculates the relative distance between the object and the first flat surface or the second flat surface according to the position of the speckle pattern on the object image information and the displacement vector.
