| 摘 要： | 研究了基于立体视觉的三维反向建模方法。该方法利用线状结构光与立体视觉原理,首先测量位于四自由度平面机器人上的三维物体的表面几何信息,然后通过获得的采样数据集,自动构建具有真实纹理的三维几何模型。相应提出了一种新的系统标定方法与自动曲面重构算法,并实现了一个面向虚拟现实应用的三维物体的自动反向建模原型系统。

| Abstract: | A stereo vision-based three-dimensional(3-D)reverse modeling approach was investigated.Linear structured light and stereo vision measurement principles were used to acquire geometric information through sampling the surface of a physical object mounted on the end-effector of a 4-DOF planar robot.Based on real-world sampling datasets,a realistic 3-D graphical model could be automatically built.For purpose of this,a new approach to system calibration and automatic surface reconstruction was proposed,and a prototype system of rapidly establishing a textured model was implemented for virtual reality application. |
