In　order　to　maintain　and　improve　the　visual　experience　and　comfort　of　stereoscopic　video,　disparity　adjustment　becomes　one　of　the　key　technologies　of　3D　applications.　To　solve　the　deformation　problems　of　the　traditional　algorithm,　this　paper　proposes　a　precise　parallax　regulation　model.　Through　affine　transformation　method,　the　model　solves　the　problem　of　parallax　adjustment　after　the　object　deformation.　But　this　model　needs　to　get　the　original　depth　value　to　adjust　the　parallax,　and　the　high　computational　complexity　leads　to　hardly　playing　high　resolution　3D　video　images　fluently.　Therefore,　we　further　introduce　the　minimum　deformation　range　to　be　detected.　By　assuming　the　original　depth　of　the　statistical　model,　the　deformation　size　can　be　controlled　below　the　minimum　deformation,　which　makes　a　proper　balance　between　complexity　and　deformation　degree.　Finally,　the　modeling　analysis　and　VLC　player　integrating　experiments　show　that　the　proposed　algorithm　reduces　the　degree　of　deformation　by　more　than　50%　compared　with　traditional　methods,　and　has　better　subjective　stereoscopic　effects.　For　high-definition　videos,　the　efficiency　of　the　algorithm　is　improved　by　48%.
