Translation motion estimation is the major aspect of video motion compensation  especially in two-dimensional turntable. This paper presents a robust parallel estimation algorithm of translation in video stabilization system. The equivalent model of translation that derived is accorded with small rotation angle comparatively. A parallel algorithm based on grey mapping is used in local motion estimation to shorten the estimation time and improve the computation efficiency. After local motion vectors are calculated  a fast filter can detect the spurious vectors avoiding possible jerks. The suggested translation estimation algorithm has been implemented on NVIDIA GTX 260  the experimental results show that  the average time of the estimation and compensation finished in 16 ms/frame  and stabilize 1k1k pixels sequence gray video up to 60 frames/s. 2010 IEEE.
