摘要 在计算机三维动画制作中,要制作一个具体的真实物体的三维模型,是一项复杂而困难的事情。本文根据由阴影恢复形状的视觉理论,利用光度立体视觉技术,给出了由3幅光移图象计算物体表面方向和深度信息,并利用贝塞尔曲线拟合获得物体表面的结构模型的方法。 s It's a complicated and difficult task to construct 3D model of real object when makeing 3D stutio.Based on the computer vision theory of shape from shading and photometric stereo techinque,this paper proposes a method,which can calculate the gradients of surface and height information from three grey images,and finaly constructs the 3D model by using the draft of Bezier curve.
