Whats the best way to use Building Recognition in Unity using ARFoundation?

I have done my research, but i did not get the results that i wanted. I followed the Instructions of this video https://www.youtube.com/watch?v=I9j3MD7gS5Y.

My Code of the ARTrackedImages:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.XR;
using UnityEngine.XR.ARFoundation;

[RequireComponent(typeof(ARTrackedImageManager))]
public class MultipleImageObjectRecognition : MonoBehaviour
{
    [SerializeField]
    private GameObject[] placeablePrefabs;

    private Dictionary<string, GameObject> spawnedPrefabs = new Dictionary<string, GameObject>();
    private ARTrackedImageManager trackedImageManager;

    private void Awake()
    {
        trackedImageManager = FindObjectOfType<ARTrackedImageManager>();

        foreach(GameObject prefab in placeablePrefabs)
        {
            GameObject newPrefab = Instantiate(prefab, Vector3.zero, Quaternion.identity);
            newPrefab.name = prefab.name;
            spawnedPrefabs.Add(prefab.name, newPrefab);
        }
    }

    private void OnEnable(){
        trackedImageManager.trackedImagesChanged +=ImageChanged;
        Debug.Log("Added Image");
    }

    private void OnDisable(){
        trackedImageManager.trackedImagesChanged -=ImageChanged;
        Debug.Log("Remove Image");
    }

    private void ImageChanged(ARTrackedImagesChangedEventArgs eventArgs)
    {
        foreach(ARTrackedImage trackedImage in eventArgs.added)
        {
            UpdateImage(trackedImage);
            Debug.Log("added Image " + trackedImage.name);
        }
        foreach(ARTrackedImage trackedImage in eventArgs.updated)
        {
            UpdateImage(trackedImage);
            Debug.Log("updated Image " + trackedImage.name);
        } 
        foreach(ARTrackedImage trackedImage in eventArgs.removed)
        {
            spawnedPrefabs[trackedImage.name].SetActive(false);
            Debug.Log("removed Image " + trackedImage.name);
        }
    }

    private void UpdateImage(ARTrackedImage trackedImage)
    {
        string name = trackedImage.referenceImage.name;
        Vector3 position = trackedImage.transform.position;

        GameObject prefab = spawnedPrefabs[name];
        prefab.transform.position = position;
        prefab.SetActive(true);

        foreach(GameObject go in spawnedPrefabs.Values)
        {
            if(go.name != name)
            {
                go.SetActive(false);
                Debug.Log(go.name + " has been removed");
            }
        }
    }
}

The first problem that occured, was that the Images of the Buildings I have taken, did not work with the „arcoreimg“-Tool (not enough Keypoints). So I found some random pictures, which get a Score of 70.

(For the testing: I have 2 Images with a score above 70 and two GameObjects.)

Secondly when the Image gets recognized by the ArApp the GameObject appears, but when i move the recognized Image, the GameObject does not Update properly. It just stays at the first recognized position. Sometimes i can switch between the two pictures and the correct Gameobject appears. But most of the time it does not work properly. And i am using the Lunar Console and it seems like the app ends up in an endless loop Log output:

Maybe it has something to do with UpdateImage() or is there even a better/more accurate way to image recognition
