基于双目的三维点云数据的获取与预处理

在计算机辅助几何设计、医学诊断、物体识别与定位等领域的应用需求下，三维点云数据的获取与处理技术受到越来越多的关注。现在有多种不同的方式可以获取现实世界中物体的三维点云数据，并对数据进行相应处理。为了能够很好地对三维数据点云进行前期的预处理，首先通过双目摄像机获取物体的三维点云，并采用八叉树法对点云数据进行相应的预处理，然后在逆向工程软件中描述出来，从逆向工程软件中可以看出得到的物体与实际物体比较接近，从而可以证明所获取的点云数据可以用来描述物体，并且点云数据的处理技术是可行的。

Three-dimensional Point Cloud Data Acquisition and Pre-processing Based on Binocular

Under the application requirements of computer aided geometric design,medical diagnosis,object recognition and positioning, 3D point cloud data acquisition and processing technology is paid more and more attention. There are many different ways you can get and handle 3D point cloud data objects in the real world. To be able to preprocess three-dimensional point,through binocular cameras get 3D point cloud object firstly,using oc-tree method to the corresponding point cloud data pre-processing,and then in the reverse engineer-ing software to be described,from reverse engineering can be seen in the actual body of the object obtained relatively close,which can prove the acquired point cloud data can be used to describe the objects,and point cloud data processing technique is feasible.
