AR Foundation Simplified image recognition

Hello, I have a question,

Could you with ImageTracking use a simplified image instead of a real image?

For example, I have an image of a car with two wheels and two windows. But instead of using that image, I want to use with two squares and two circles, so I can use ImageTracking with two different cars.

Thanks

 

Yes, this is possible. You simply need to write your own image visualizer and replace detected image by a real one.
Here is an idea:

Code (CSharp):

1. using System.Linq;
2. using UnityEngine;
3. using UnityEngine.Assertions;
4. using UnityEngine.XR.ARFoundation;
5.  
6.  
7. public class TrackedImagesVisualizer : MonoBehaviour {
8.     [SerializeField] ARTrackedImageManager manager = null;
9.  
10.  
11.     void Awake() {
12.         manager.trackedImagesChanged += trackedImagesChanged;
13.     }
14.  
15.     void OnDestroy() {
16.         manager.trackedImagesChanged -= trackedImagesChanged;
17.     }
18.  
19.     void trackedImagesChanged(ARTrackedImagesChangedEventArgs args) {
20.         foreach (var trackedImage in args.added.Concat(args.updated)) {
21.             // todo set scale and position
22.             var mr = trackedImage.transform.GetComponentInChildren<MeshRenderer>();
23.             Assert.IsNotNull(mr);
24.             mr.material.mainTexture = getRealImage(trackedImage.referenceImage.name);
25.         }
26.     }
27.  
28.     Texture getRealImage(string imageName) {
29.         throw new System.NotImplementedException("todo: replace detected image with real one");
30.     }
31. }
32.  

 

thanks
