Confusion with the screen coordinates

August 10, 2017 - 12:53pm #1

Hi,

I am changing the User Defined Targets sample to a masters degree project. I followed this post

https://developer.vuforia.com/forum/faq/technical-how-can-i-project-target-point-screen

to get the coordinates of certain points on the screen in order to get the value of the pixels of those points. I am accessing pixel values ​​through the camera image as described in this post

https://developer.vuforia.com/forum/faq/android-how-can-i-access-camera-image

However, the screen coordinates appear to be in the dimension determined by the mScreenWith and mScreenHeight variables that for my phone are assuming 1080x1920 values ​​while the camera image resolution is 1280x720. Is there any way to get the coordinates of the screen within the dimensions of the frame? Or get a frame in the resolution of the screen by another method?

I question this because performing down/up sampling is not something I want in my project.

Thanks in advance.
