Traditional　3D　models　are　often　built　around　specialized　hardware,　such　as　laser　range　finders　and　stereo　rigs,　which　are　expensive　and　complex　to　manipulate.　In　this　paper,　a　method　that　achieves　3D　reconstruction　just　using　one　consumer　grade　family　camera　is　proposed.　First,　two　images　of　the　same　scene　from　different　viewing　positions　are　captured　without　any　strict　constraints;　Second,　extrinsic　parameters　of　the　camera　are　estimated　and　refined;　Then,　image　rectification　is　achieved　to　align　epipolar　lines　of　both　images　with　scan　lines;　Finally,　3D　model　reconstruction　is　completed　with　the　disparity　map　and　the　geometry　of　cameras.　The　proposed　method　is　convenient　even　for　amateurs　and　can　produce　vivid　3D　models　in　a　variety　of　different　environments.　©　2012　IEEE.
