Target Management

This guide gives you an overview of how to create a target collection that you can use to detect and track images within your augmented reality experience.

In general the conversion can be done via four different tools:

  1. Wikitude Studio Manager: A browser based tool to convert your images to a wtc file. You can find the tool under: You need your free developer account to log-in. This tool is described in more detail further below.
  2. WTC Editor within Unity Editor: The Wikitude Unity plugin installs a WTC Editor as extension of the Unity Editor. Unity developers can manage all their targets and target collections directly within Unity Editor. Please consult the Unity documentation on more details.
  3. RESTful API: The Cloud Recognition Manager API provides a RESTful API to upload target images and convert them to wtc files. Read more details in the section about Cloud Recognition API
  4. Targets Enterprise Script: A binary shell script available for Mac OS X and Linux converting images to target collections. Pleases contact Wikitude Sales team for technical requirements and pricing.

The following images describes the relationship between the above mentioned methods and the Wikitude Cloud Recognition Service, which is not scope of this documentation.

Add target images

If you add your own target images you need the target name to set them in AR.Trackable2DObject.

General advice for reference images

Create a WTC file

Use project's WTC file in your ARchitect World

Look at one of the client recognition examples or refer to the JavaScript API reference of AR.ClientTracker for instructions on how to use the created target collection for augmentations in your ARchitect Worlds.

Cloud Recognition

Any existing project may also be published to the Cloud to make it accessible for AR.CloudTracker.

Click the Cloud icon in the toolbar for more details.

Cloud Recognition is available for free in your testing process but you must purchase a license for productive use. Learn more

Once a project is published it is accessible via Wiktiude SDK using 'Client Token' and 'Target Collection ID' (compare AR.CloudTracker)


Targets Versioning
