投影和查看矩阵以匹配Kinect RGB相机透视图 [英] Projection and View matrices to match the Kinect RGB camera perspective

问题描述

为了与Kinect RGB相机匹配，有人知道为XNA渲染设置投影和视图矩阵的正确值是什么吗?

Does anybody know what are the correct values to setup the projection and view matrix for a XNA rendering in order to match with the Kinect RGB camera?

例如，如果骷髅头关节坐标为(X，Y，Z)，则如果我在3D空间中的这些坐标处绘制一个球体，则渲染应与RGB图像中的头部重叠.

For example, if the skeleton head joint coordinates are (X,Y,Z) then if I draw a sphere at these coordinates in my 3D space, the rendering should overlap the head in the RGB image.

推荐答案

最后，我采用了试错法并确定了参数. 您可以在此处找到更多详细信息: http://www.mindtreatstudios.com/our-projects/kinect-3d-view-projection-matrix-rgb-camera/

In the end I took a trial and error approach and determined the parameters. You can find more details here: http://www.mindtreatstudios.com/our-projects/kinect-3d-view-projection-matrix-rgb-camera/

我确信这不是重构3D空间的最科学方法，但是鉴于我有可用的时间范围和项目的需求，它们运行良好，并且对结果感到满意.

I'm sure this is not the most scientific way of reconstructing the 3D space, but given the time-frame I had available and the needs of my project, they work well and I'm happy with the results.
