About Target's screen position

April 5, 2014 - 7:42am #1

Hello eveyone!

I search the forum about the teapot or target's postion.

And I have a question.

 

How can I get target's screen postion?

 

I know that the camera have three-dimensional.

But on the screen's coordinate have the x and y axis. No z axis.

So I should convert camera's coordinate to screen coordinate? Right?

I study the ImageTarget example. But in that code I can't find any solution.

Dose anyone can help me?

Thanks you!

First, thanks your reply! I feel sorry about that. I not quickly reply for this question.

Second, I have seen that article.

But I still have no idea. And I search about this topic in the forum.

I found i can use getpose to get target position.

But it format is Mattrix34F.

And how can I convert it to the x and y value?

Thanks!
