ARToolKit UnityPackage and Epson BT-300

Postby AR_Markus » Thu Mar 16, 2017 12:15 am


I would like to work with ARToolkit for Unity and the glasses.

What configurations must be made in Unity to run the app on the glasses? And why?


The app runs on my tablet but on the glasses it starts briefly and breaks off.

Thanks a lot,

Hello Markus,

You usually need to set the see through optical display option. ... ee-through

Hello Markus,

connect your BT-300 to your android studio and check for errors. I can imagine that it is the same problem like BT-2000. Check the log for following line:

Code: Select all

hardware/ti/omap4xxx/camera/CameraHal.cpp:3547 isEpsonCameraParameterValid - Invalid parameters combination on single-through-720p mode with preview size (320x240

It basicly means modern cameras don't support 320x240 camera size anymore whats the default in the current ARtoolkit.

If you find it try this thread to solve it:
