The stereo camera system comprises a camera and a prism arranged at a desirable distance from the front side of the lens of said camera . The prism may be a delta shaped biprism having a base , a first incline and a second incline , in which both the first incline and said second incline obliquely face the lens of said camera . Alternatively, the prism may be a trigonal pyramid shaped triprism having a base and three inclines, in which the three inclines obliquely face the lens of said camera. The camera may be a charge coupled device camera. The present invention also relates to a distance measurement system and a distance measurement method for measuring distance between the stereo camera system and an object using disparity of a stereo image of the object.
