With AVFoundation's builtInLiDARDepthCamera, if I save photo.fileDataRepresentation to heic, it only has Exif and TIFF metadata. But, RealityKit's object capture's heic image has not only Exif and TIFF, but also has HEIC metadata including camera calibration data. What should I do for AVFoundation's exported image has same meta data?

With code below, I added color and depth image from RealityKit ARView, and ran Photogrammetry on iOS device, the mesh looks fine, but the scale of the mesh is quit different with real world scale. let color = arView.session.currentFrame!.capturedImage let depth = arView.session.currentFrame!.sceneDepth!.depthMap //😀 Color let colorCIImage = CIImage(cvPixelBuffer: color) let colorUIImage = UIImage(ciImage: colorCIImage) let depthCIImage = CIImage(cvPixelBuffer: depth) let heicData = colorUIImage.heicData()! let fileURL = imageDirectory!.appendingPathComponent("\(scanCount).heic") do { try heicData.write(to: fileURL) print("Successfully wrote image to \(fileURL)") } catch { print("Failed to write image to \(fileURL): \(error)") } //😀 Depth let context = CIContext() let colorSpace = CGColorSpace(name: CGColorSpace.linearGray)! let depthData = context.tiffRepresentation(of: depthCIImage, format: .Lf, colorSpace: colorSpace, options: [.disparityImage: depthCIImage]) let depth_dir = imageDirectory!.appendingPathComponent("IMG_\(scanCount)_depth.TIF") try! depthData!.write(to: depth_dir, options: [.atomic]) print("depth saved") And also tried this. let colorSpace = CGColorSpace(name: CGColorSpace.linearGray) let depthCIImage = CIImage(cvImageBuffer: depth, options: [.auxiliaryDepth : true]) let context = CIContext() let linearColorSpace = CGColorSpace(name: CGColorSpace.linearSRGB) guard let heicData = context.heifRepresentation(of: colorCIImage, format: .RGBA16, colorSpace: linearColorSpace!, options: [.depthImage : depthCIImage]) else { print("Failed to convert combined image into HEIC format") return } Does Anyone know why and how to fix this?

I'm really excited about the Object Capture APIs being moved to iOS, and the complex UI shown in the WWDC session. I have a few unanswered questions: Where is the sample code available from? Are the new Object Capture APIs on iOS limited to certain devices? Can we capture images from the front facing cameras?
