Tutorial: Step by Step Guide for Creating an Object Target Collection


IMPORTANT NOTE: THIS TUTORIAL IS ONLY APPLICABLE FOR SDK 7.x. SDK 8 OFFERS A NEW WAY OF CREATING .wto FILES. PLEASE REFER TO THE SDK DOCUMENTATION FOR DETAILS ON THE SDK 8 PROCESS.


In order to be able to track your own 3D object you first need to create a video of this object. The next step would be that you upload this video on our Studio in order to create a .wto file which is the ObjectTargetCollection that you will use in your own app.


This tutorial describes all the steps you need to take in order to be able to create and put your .wto file into your application. The tool that is used in this process is Wikitude Studio so you must have an account there before you begin with the process or create a new one.


1. The first step would actually be, choosing a suitable object. You can follow this article "Best Practice: How to choose a suitable Object Target" to review which objects are considered good candidates and which ones are considered rather bad candidates.


2. Once you have selected your object target you can create a video with the 3D object you want to track. For more information regarding best practices for creating such a video please refer to this Tutorial “Best practice for video recording for Object Recognition”.


2. You need to Log into Studio manager in targetmanager.wikitude.com. In Studio manager you can either create a new .wtc file (this is used for image recognition) or in our case an ObjectTargetCollection by selecting ADD PROJECT.


3. In the pop up box you select Object as a Type and name your collection

4. Once you create a new Object then click on the folder. In this new window select ADD OBJECT TARGETS and in the pop up box upload your video by clicking on the grey box area. Please note that is advisable you do reduce the size of your video using online tools.


5. If the upload was successful then you see the screenshot below. Now you need to select the device you used for recording your video from the drop down list. If your device is not listed there then choose Custom and add the Field Of View (FOV) of your device.

6. Once you click CREATE TARGET you need to wait for the .wto file to be generated.


7. Now that you have created your own .wto file you can either double click it in order to have an estimate of how ….. (and maybe see if the video recording of your object and the selection of the object itself was successful or you would need to repeat the process) or click on the .wto file once and select the download wto button from the menu on the right. The file will be sent to your email address.
