    Abstract: A distance measurement system and method are provided. The distance measurement method first projects a light beam with a speckle pattern to reference planes and an object to allow the reference planes and a surface of the object each have an image of the speckle pattern, the speckle pattern having a plurality of speckles. Next, images of the speckle pattern reflected by the reference planes are captured to generate reference image information, and an image of the speckle pattern reflected by the surface of the object is captured to generate an object image information. A processing module which may be a processing software can compare the object image information with the reference image information to obtain several similarity scores. If the most the most similarity score is greater than a threshold value, the processing module identifies the corresponding reference plane, thereby computing the position of the object.
