Claim One:
1. A non-transitory storage media, has a non-transitory processing software for computing a position of an object in a distance measurement system, the execution of the processing software comprising: receiving a plurality of reference image information contained in an image with a speckle pattern, wherein the image is projected from a light beam on a plurality of reference flat surfaces which are located on different position points, and the speckle contains a plurality of speckles; receiving an object image information contained in an image with the speckle pattern which is projected from the light beam on an object; obtaining a plurality of comparison results through comparing the plurality of reference image information with the object image information; and computing the position of the object through performing an interpolation operation to the plurality of comparison results; wherein the step of obtaining a plurality of comparison results through comparing the plurality of reference image information with the object image information comprises: obtaining a plurality of similarity scores through comparing the plurality of reference image information with the object image information, and defining the plurality of similarity scores as the plurality of comparison results; wherein the step of computing the position of the object through performing an interpolation operation to the plurality of comparison results comprises: selecting at least two similarity scores with highest values from the plurality of similarity scores; and computing the position of the object through performing the interpolation operation to a ratio of these at least two similarity scores with highest values.
