2D Targets (Image Targets)
Last updated
Last updated
Image Targets refer to 2D images which Vuforia can recognise and track. These image targets work in a similar way to QR codes, but full colour images can be used.
The Vuforia Target Manager supports .jpg
and .png
images that are 2 MB or smaller. These images can be RGB or Grayscale. The features of the image are graded based on how well the engine is able to track them. Learn more here:
The basic workflow for working with Image Targets is as follows:
Upload the image to the Vuforia Target Manager online. You can also use one of the sample Image Targets.
Download the updated Target Manager Database.
Add the image target to your project in Unity
Add the Device Database
Add and Configure the Image Target as a GameObject
Add an ARCamera
Add an ImageTarget
Assign Content to the ImageTarget
The basic workflow within Unity is extremely similar to that of 3D (Object) Targets.
If you haven't already, download the device database from your Vuforia Target Manager.
Import the .unitypackage
file by heading to Asset > Import Package
See: Device Databases
Add an ARCamera
instance to your scene.
GameObject > Vuforia > ARCamera
Generate and add your license information to the ARCamera
in the Inspector Window
Add an ImageTarget
instance to your scene.
GameObject > Vuforia > 3D Scan
Change the Image Target Behaviour. With the ImageTarget
selected, change the Type
, Database
and Image Target
fields in the Inspector Window
Add any content you desire to augment the image. This can be 2d content such as text or 3d assets such as .FBX
files.
In this case, we have named our content Cube.
Make the content a child of the ImageTarget
. This way the content will only be displayed once the ImageTarget
is recongnised.
Use the Play button in the toolbar
to test the application.
