minimum size image target

August 3, 2016 - 3:09am #1

Hi there,
I tried a recognition with the attached image (2x2 cm). It works, actually not very well, with the PC camera. Does someone know how much should be the minimum size of an image target?

Thank you

Hello,

If the target can fill up enough of the camera's FOV, then Vuforia can detect it.

However, many web and device cameras struggle to maintain constant focus in Macro mode. This, in turn, affects the ability of the SDK to detect and/or track the target.

Thanks

Based on the extensive testing I've done I wouldn't go smaller than 1 inch x 1 inch for a marker. We've had a lot of success with markers between 1x1 inch and 2x2inch in terms of various designs.
