    Hello everyone,

    In my android project I want to recognize an image of the periodic table, which can be of different sizes. For example, it may be the size of an a4 or an a3 or larger.

    When I tried to set width of an image target to a width of a4, it only worked if I moved the camera some distance and sometimes with other sizes it didn't work at all.

    What should I do to set the size for different tables?

    Hi,

    Image target recognition works based on the scaling you introduced in the TargetManager when uploading the image.So it would be an *expected behavior* to have difficulties recognizing a bigger image than the one uploaded.

    A workaround that comes to mind ( but possible a tedious one) would be to add the same image with different sizes: A4, A3, A2 etc in the Target Manager and then add them to your scene.

    Thank you.
