A　convenient　texture　roughness　calculation　method　for　binary　image　is　present　at　the　first　part　of　this　paper.　And　put　the　emphasis　on　the　analyzing　of　the　relationship　between　the　pose　of　the　camera　fixing　on　the　robot　and　the　roughness　of　the　texture　image,　which　provides　the　theory　of　the　vision　servoing　based　on　the　texture　features　analyzing.　Emulation　result　shows　that　the　method　of　texture　roughness　calculation　present　here　is　efficient　useful　for　expressing　the　pose　of　the　camera,　and　the　method　can　be　used　in　the　vision　servoing　based　on　the　texture　features　analyzing.　©　2011　IEEE.
