Targets give you the ability to position your AR content on any surface, marker or image
Marker-based Augmented Reality
A marker is giving the Augmented Reality (AR) application a visual clue or trigger where to position AR content. The marker can be an image, a logo or any type of distinguishable 2D object that can be recognized by the camera. Due to its use of image recognition, this type of AR is sometimes also called recognition-based AR.

Marker-based vs. surface detection
Instead of using a traditional 2D marker, some AR applications can also detect surfaces and use these as a marker instead. This is an advantage if you want to let the user decide where they are going to place the content or if you want to work with large models where scale and accuracy of model size are important. This can be the case for furniture, machines or even cars.
How to select a good marker for Augmented Reality?
The quality of the image that is being used as an AR trigger is really important. Quality does not necessarily refer to resolution but to how recognizable the marker is for the camera and the underlying image recognition software. Important aspects are the contrast, number of lines, texture changes etc.. The quality of the marker depends on the number of key points that are found when pre-processing the marker. The more visual details a marker has, the better it is going to work.
Use cases for marker-based AR
Marker-based AR is widely used in areas where visual content is superior. We have collected some examples of usage in marketing, education and real estate.
