摘要：

Techniques　of　micro　stereovision　coupled　with　a　stereo　light　microscope　and　two　image　sensors　are　applied　to　micromanipulation,　micro-assembly　and　micro-measurement,　etc.　For　micro　stereovision,　a　vision　model　should　be　given　in　order　to　calculate　coordinates　in　the　objective　reference　frame　from　image　coordinates　of　two　imaging　reference　frames.And　stereo　matching　methods　for　stereo　images　are　used　for　finding　correlated　features.　So　the　relative　rotation　of　two　image　sensors　can　bring　errors　when　a　vision　model　is　used　for　calculating　coordinates　of　the　objective　reference　frame.　In　this　paper,　an　error　correction　method　of　image　seneor　rotation　for　micro　stereovision　is　proposed.　Experiment　results　indicate　that　precision　is　increased　about　6%　after　correcting　the　error　from　image　sensor　rotation.
