Claim One:
1. A distance measurement system, comprising: at least one reference plane; a light source module, providing a light beam having a speckle pattern to the at least one reference plane and an object, so as to show a plurality of images having the speckle pattern on the at least one reference plane and a surface of the object, wherein the speckle pattern has a plurality of speckles; an image capture device, capturing the image shown on the reference plane to perform a reference image information, and capturing the image shown on the surface of the object to perform an object image information; and a processing module, coupled to the image capture device for obtaining the reference image information and the object image information, and calculating a plurality of brightness relationships between each of the speckles and adjacent speckles rounding each speckle in the reference image information and the object image information to obtain a relative brightness information of each of the speckles, so as to calculate the position of the object according to the relative brightness information.
