Ios 带有跟踪图像的ARKit场景开始跳跃

发生了一些奇怪的事情，我刚刚创建了一个简单的应用程序。我的应用程序可以跟踪图像，我在图像上添加了一个SCNPlane。但是，当我的图像获得某种透视效果时，SCNPlane开始跳跃。请观看视频以便更好地理解：

所以，正如你们看到的，当我检测到像“布鲁斯·韦恩”这样的简单图像时，一切都很好，但当我试图检测到“建筑”时，它开始跳跃。 我想阿尔基特人不知道如何准备这张图片，但我不知道如何修复它以及从哪里开始

下面是一些代码：

...

 override func viewDidLoad() {
        super.viewDidLoad()
        initScene()
    }
    
    func initScene(){
        sceneView.delegate = self
        sceneView.showsStatistics = true

        // Create a new scene
        let scene = SCNScene(named: "art.scnassets/videoScene.scn")!
        self.sceneView.autoenablesDefaultLighting = false

        // Set the scene to the view
        sceneView.scene = scene
    }

...

  override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        openedDetailScreen = false
        let configuration = ARImageTrackingConfiguration()
        configuration.trackingImages = arImageReference
        configuration.maximumNumberOfTrackedImages = 2
        
        self.sceneView.debugOptions = [ARSCNDebugOptions.showFeaturePoints, ARSCNDebugOptions.showWorldOrigin]
        self.configuration = configuration
        sceneView.session.run(configuration)
        
        initRecognition()
        
    }

...

  func renderer(_ renderer: SCNSceneRenderer, didAdd node: SCNNode, for anchor: ARAnchor){
        
        guard anchor is ARImageAnchor else { return }
        
        guard let currentReferenceImageName = ((anchor as? ARImageAnchor)?.referenceImage) else {
            return
        }
        print("size of tracked images \(currentReferenceImageName.name)")
        
        addVideoScene(withImage: currentReferenceImageName, didAdd: node)
    }

...

  private func addVideoScene(withImage referenceImage: ARReferenceImage,didAdd node: SCNNode){
        videoNode = SKVideoNode(avPlayer: videoPlayer)
        let videoScene = SKScene(size: CGSize(width: 480, height: 360))
        // center our video to the size of our video scene
        videoNode.position = CGPoint(x: videoScene.size.width / 2, y: videoScene.size.height / 2)
        // invert our video so it does not look upside down
        videoNode.yScale = -1.0
        videoScene.addChild(videoNode)
        // create a plan that has the same real world height and width as our detected image
        let plane = SCNPlane(width: referenceImage.physicalSize.width, height: referenceImage.physicalSize.height)
        // set the first materials content to be our video scene
        plane.firstMaterial?.diffuse.contents = videoScene
        // create a node out of the plane
        let planeNode = SCNNode(geometry: plane)
        // since the created node will be vertical, rotate it along the x axis to have it be horizontal or parallel to our detected image
        planeNode.eulerAngles.x = -Float.pi / 2
        node.addChildNode(planeNode)
    }

图像跟踪的质量在标记本身的质量（例如，可以识别多少“特征点”）、周围环境的质量（是否曾想知道为什么所有苹果ARKit演示都在大屏幕、纹理表上？）和打印标记的质量之间存在很大差异。因为你的图像只是显示在监视器上，所以跟踪质量不是很好。尝试打印图像，然后在那里重试。

给我一些时间进行测试）我会在相同的结果后返回，我在iPhone 6s和XS Max上进行了测试。也许我们可以在图像上设置一些默认参数，而无需跟踪透视图。更新结果：
