Reconstruction of 3D structure of an object from 2D views plays an important role in plastic surgery and orthopedics. This method doesn't need camera to do specific movements, such as translation or rotation independently. It only needs a hand-hold camera arbitrarily to take a few pictures, and apply the geometry relationship among the three views to obtain the projective reconstruction of the object. Then, it needs to introduce cheirality constraint in stratified reconstruction to determine the search area of the infinity plane, and finally achieve the camera intrinsic parameters calibration, and complete the metric reconstruction. This model has also been reconstructed with mouse and keyboard response coordinates to observe the model from different angles. Experiments with both pictures of object and face pictures show that the proposed method is very robust and accurate.
从二维视图重建物体的三维结构在整形外科和骨科中起着重要作用。该方法不需要相机进行特定运动，如单独平移或旋转。只需要手持相机随意拍摄几张照片，并应用三个视图之间的几何关系来获得物体的投影重建。然后，在分层重建中需要引入手性约束来确定无穷远平面的搜索区域，最终实现相机内参标定，并完成度量重建。该模型还通过鼠标和键盘响应坐标进行了重建，以便从不同角度观察模型。对物体图片和面部图片的实验均表明，所提方法非常稳健且准确。
