摄像机坐标系的不同描述

在3D模式下，您可以通过查看在您平移相机时变得可见的模糊3D投影线来更好地了解相机的透视图。
Ir投射视野，该视野从相机成像器原点的一个点开始，并向各个方向向外扩展。
因为很难看到这些线条，所以我在我的艺术软件中追踪它们以更好地说明它们。
无论相机从其视角看什么，流上的Z深度箭头都朝向前方。
因此，Z距离将是正的，因为检测到的Z随着物体沿箭头方向远离相机而增加。 
不可否认，如果Y-down =正数，我对Y箭头的方向没有解释。



以下为原文

In 3D mode, you can get a better idea of the camera's perspective by looking at the faint 3D projection lines that become visible if you pan the camera around.  Ir projects a field of view that starts at a point at the camera's imager origin and widens outwards in all directions.
 
Because the lines are hard to see, I traced over them in my art software to illustrate them better.
 

 
The Z-depth arrow on the stream faces forward at whatever the camera is looking at from its perspective.  So Z-distance will be positive because the detected Z increases as an object moves away from the camera, in the direction of the arrow.
 
  Admittedly, I do not have an explanation for the direction of the Y arrow if Y-down = positive.

因此，当我获得某些对象的3D坐标时，Viewer中的坐标系统无关紧要。
是对的吗？



以下为原文

So the coordinate system in the Viewer doesn't matter when I get my 3D coordinates of some  objects . Is that right?

依靠脚本输出的3D XYZ坐标肯定会更容易。
您无法从3D模式下的查看器中的屏幕箭头获得更多有意义的信息，因为 - 与2D模式不同 - 没有坐标读数。



以下为原文

It would definitely be easier to rely on 3D XYZ coordinates output by a script.  You can't get much meaningful information from the on-screen arrows in the Viewer in 3D mode, since - unlike 2D mode- there is not a coordinate readout. 

好的，非常感谢 ！

okay, Thank you very much !
