如何使用Kinect获取3D图像？ [英] How I can get 3D Images with Kinect?

问题描述

Kinect为我们提供了可用于拍摄3D图像的相机。如何获取3D图像并将其保存在OBJ文件中？ 

Kinect offers to us cameras that can be used to get 3D images. How can I get 3D images and save it in OBJ file? 

推荐答案

Kinect SDK beta提供了（A）API来获取骨架关节3D空间中的人体骨骼，并且还提供（B）深度图像流，其可以用于生成表示Kinect正在观看的环境的3D网格。为了直接从（B）生成3D对象
，存在多种策略，并且有效的策略是"KinectFusion：Real-Time Dynamic 3D Surface Reconstruction and Interaction"。 （ http://research.microsoft.com/apps/pubs/default。 aspx？id = 152807 ），
这是为SIGGRAPH 2011写的一篇论文。我建议找那篇论文来了解他们是如何做到的。

The Kinect SDK beta provides (A) APIs to get skeleton joints for a human skeleton in 3D space, and also provides (B) a depth image stream, which can be used to generate 3D meshes that represent the environment that Kinect is viewing. To generate 3D objects directly from (B), there are multiple strategies, and an effective one is "KinectFusion: Real-Time Dynamic 3D Surface Reconstruction and Interaction" (http://research.microsoft.com/apps/pubs/default.aspx?id=152807), which was a paper written for SIGGRAPH 2011. I'd recommend looking for that paper to learn how they did it.

关于OBJ文件，我猜你的意思是Wavefront OBJ文件（ http://en.wikipedia.org /wiki/Wavefront_.obj_file ）。要保存在这样的OBJ文件中，您必须熟悉
文件格式，然后自己编写代码，以便在拥有3D网格后输出该格式的文件。

About OBJ files, I'm guessing you mean Wavefront OBJ file (http://en.wikipedia.org/wiki/Wavefront_.obj_file). To save in such an OBJ file, you would have to become familiar with the file format and then write the code yourself to output a file in that format after you have the 3D mesh.
