OpenGL环境下点云模型的显示变换，介绍一种标准的3D点云模型OBJ文件的特点和基本结构,在VC++6.0平台下结合OpenGL完成了OBJ格式文件的读取和点云模型的三维显示、旋转、平移、缩放变换功能.实验结果表明,利用OpenGL开发的程序可以高效实时地实现点云的各种操作.-OpenGL environment, the display of point cloud model of transformation to introduce a standard 3D point cloud

本电子文档详细介绍了坐标转换的线性方法，与传统的非线性方法相比，不需迭代即可进行，非常值得一看。-This electronic document details a linear coordinate transformation method, compared with the traditional nonlinear method without iteration can be carried out is worth a visit.

Motion estimation is the process of determining motion vectors that describe the transformation from one 2D image to another usually from adjacent frames in a video sequence. It is an ill-posed problem as the motion is in three dimensions but the ima
