Importing and activating the Target Database in Unity

Setting up Image Targets

This section shows you how to set up a simple Image Target and get it responding to basic tracking events.

To allow your application to recognize images and use them as Targets to trigger gameplay, display graphics or information, you need to create a Target database. You can create Target databases directly from the Vuforia Developer Portal Target Manager page, as the steps in this section describe.

Log into your Vuforia Developer account. Then navigate to the Target Manager page and click on the Add Database button.

The Width value is a scale value that you need to set to the size you want the image to appear in your Unity SceneA Scene contains the environments and menus of your game. Think of each unique Scene file as a unique level. In each Scene, you place your environments, obstacles, and decorations, essentially designing and building your game in pieces. More info

(in real-world units). Unity measures everything in your Scene in relation to the size of your Target image. For this example, the width of the playing card is 5.5cm, so you would use 5.5cm as the Width value. If you need a larger size Target, then increase this Width.

The image appears in the list of Targets with a Rating value represented by stars. If your Rating is less than 5 stars, it may be harder for the camera to track it. To learn more about what affects Image Target ratings, see Vuforia documentation on Optimizing target detection and tracking stability.

Once you are satisfied with your image’s Rating, select the checkbox to the left of the Image Target name and click the Download Database button.
