Micro　stereo　vision　based　on　a　stereo　light　microscope　is　applied　to　three-dimensional　reconstruction　and　scale　measurement　of　micro　parts.　A　vision　model　serves　for　connecting　two　image　spaces　and　an　object　space,　and　is　responsible　for　the　calculation　of　object　space　coordinate　from　two　image　coordinate　frames.　When　a　vision　model　is　given,　two　planes　of　image　coordinate　frames　corresponding　with　planes　of　CCD　image　sensors　may　cause　error　of　coordinate　calculation　in　object　space.　The　projection　from　two-dimensional　image　space　to　three-dimensional　object　space　is　described　by　a　vision　model　in　micro-stereo　vision.　In　this　paper,　error　correction　for　vision　model　caused　by　CCD　image　sensor　rotation　is　studied.　Based　on　a　weak-disparity　vision　model,　correction　formulas　are　given,　and　position　precision　of　correctional　and　non-correctional　model　is　analyzed　and　compared.　Experiment　results　indicate　that　6%　position　precision　is　increased　after　CCD　image　sensor　rotation　is　considered.
