从单幅透视投影灰度图象识别和复原旋转体

Recognition and Shape Recovery of a Solid of Revolution from a Single View GrayLevel Image under Perspective Projection

基于旋转体的三维模型研究了透视投影下的旋转体剖节线和侧轮廓线的几何性质及其计算方法，并在此基础上成功地开发了一个从单幅透视投影灰度图象识别和复原旋转体的三维视觉信息的新技术。大量的实验表明该技术是精确、有效和可靠的。

On the basis of the 3D model of a solid of revolution, the geometric properties and algebraic formula of its limbs and crosssection curves under perspective projection are analyzed in detail. A new technique to recognize a solid of revolution and to extract its 3D vision information from its a single viewgraylevel image is successfully developed. Experiments have demonstrated that the technique is exact, efficient and reliable.
