Ambient　Intelligence　represents　the　newest　generation　computing　mode,　and　brings　some　new　requirements　for　the　traditional　machine　vision.　In　this　paper,　firstly,　new　features　of　machine　vision　applications　under　AmI　environment　are　discussed,　and　a　conceptual　AmI　optical　perception　model　is　given.　Then,　the　developing　trend　of　the　machine　vision　based　on　optical　perception　application　system　is　discussed.　After　that,　the　Optical　perception　model　in　AmI　application　system　is　given.　An　AmI　C-T　(Computing-Transporting)　dilemma　problem　is　proposed,　and　the　E-A-E　(Embedded-AmI-Embedded)　model　is　given　according　to　it.　This　model　is　put　in　use　in　the　AmI-FO　project.　Finally,　some　important　issues　and　future　research　of　AmI　optical　perception　model　are　introduced.
