Only scan image at the center camera ?

June 12, 2018 - 12:03am #1

Hello,

I am developing an application which use Vuforia library to scan AR image.

My customer want the app only scan AR image if we put the image inside the red square as the picture below. If we put AR image outside the red square, it will not scan.

Any ideal how to do this? Can we set the scan area to center of the camera view or make it only scan if we put the position of the target image at center screen.

Thank you

Hello phunq,

There is not a way to limit which area of the camera Vuforia scans, but there is a method for achieving the behaviour you're wanting. What people have done in the past is to project the position of the target they are scanning onto the screenspace and determine if it falls within the boundaries they have defined. If it does, they will augment their desired content and otherwise ignore any targets detected that fall outside of this area, not augmenting anything.

Thanks,

Vuforia Support
