Image AR markers are reference images used for image AR tracking. When the user points his phone camera on a image marker, the XR+ composition is displayed in AR, on top of the image marker.
Those markers also have a few constraints:
– They must be square.
They work best with images that have a lot of visual features. Images that work well have:
– Many sharp angles.
– High contrast. Both color and black and white images can be used.
– Many unique features that don’t repeat very often.
Photos typically makes much better image trackers than logos!
Keep in mind you don’t need to use the whole poster or photo as tracking pattern, sometimes using only a portion of it gives better results… In this example, to attach a webAR scene to this photo, it would recommended to use only the centre of the photo as tracking pattern.
