I want to align and fuse the video streams from the main camera and my external camera in visionOS 2.0, ensuring that the fused image remains directly in front of the field of view as the head moves, similar to a normal passthrough mode video image. I have already achieved and verified the static image alignment and fusion on the Vision Pro using screenshots from the main camera and the external video stream. However, I don't know how to perform real-time fusion with the main camera images. Could you please advise on how I can achieve this?

this is my code: import Foundation import ARKit import SwiftUI class CameraViewModel: ObservableObject { private var arKitSession = ARKitSession() @Published var capturedImage: UIImage? private var pixelBuffer: CVPixelBuffer? private var cameraAccessAuthorizationStatus = ARKitSession.AuthorizationStatus.notDetermined func startSession() { guard CameraFrameProvider.isSupported else { print("Device does not support main camera") return } Task { await requestCameraAccess() guard cameraAccessAuthorizationStatus == .allowed else { print("User did not authorize camera access") return } let formats = CameraVideoFormat.supportedVideoFormats(for: .main, cameraPositions: [.left]) let cameraFrameProvider = CameraFrameProvider() print("Requesting camera authorization...") let authorizationResult = await arKitSession.requestAuthorization(for: [.cameraAccess]) cameraAccessAuthorizationStatus = authorizationResult[.cameraAccess] ?? .notDetermined guard cameraAccessAuthorizationStatus == .allowed else { print("Camera data access authorization failed") return } print("Camera authorization successful, starting ARKit session...") do { try await arKitSession.run([cameraFrameProvider]) print("ARKit session is running") guard let cameraFrameUpdates = cameraFrameProvider.cameraFrameUpdates(for: formats[0]) else { print("Unable to get camera frame updates") return } print("Successfully got camera frame updates") for await cameraFrame in cameraFrameUpdates { guard let mainCameraSample = cameraFrame.sample(for: .left) else { print("Unable to get main camera sample") continue } print("Successfully got main camera sample") self.pixelBuffer = mainCameraSample.pixelBuffer } DispatchQueue.main.async { self.capturedImage = self.convertToUIImage(pixelBuffer: self.pixelBuffer) if self.capturedImage != nil { print("Successfully captured and converted image") } else { print("Image conversion failed") } } } catch { print("ARKit session failed to run: \(error)") } } } private func requestCameraAccess() async { let authorizationResult = await arKitSession.requestAuthorization(for: [.cameraAccess]) cameraAccessAuthorizationStatus = authorizationResult[.cameraAccess] ?? .notDetermined if cameraAccessAuthorizationStatus == .allowed { print("User granted camera access") } else { print("User denied camera access") } } private func convertToUIImage(pixelBuffer: CVPixelBuffer?) -> UIImage? { guard let pixelBuffer = pixelBuffer else { print("Pixel buffer is nil") return nil } let ciImage = CIImage(cvPixelBuffer: pixelBuffer) let context = CIContext() if let cgImage = context.createCGImage(ciImage, from: ciImage.extent) { return UIImage(cgImage: cgImage) } print("Unable to create CGImage") return nil } } this my log: User granted camera access Requesting camera authorization...
