I am trying to extract the 6DOF (six degrees of freedom) information from the PhotogrammetrySession.Pose using the ObjectCaptureSession in iOS. In the API documentation for PhotogrammetrySession.Pose, it is mentioned that it supports iOS 17 and later. However, in the GuidedCapture sample program, the following comment is written: case .modelEntity(_, _), .bounds, .poses, .pointCloud: // Not supported yet break Does this mean it's impossible to get 6DOF information from PhotogrammetrySession.Pose at this time? Or is there any other way to achieve this? Any guidance would be greatly appreciated.

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?

May be trivial question, but I can't find a clear answer. What interface should ICA (scanner) driver implement to communicate with the application ? i.e. to receive acquisition request with parameters and transfer image[s]. Thanks

Hey there fellas, i am a beginner on ios trying to find a way to capture/extract depthdata from a captured image in my photo gallery. I have been using xcode to achieve this task but i am particularly new to swift so i am having troubles. I need the depthdata from the image to work on it and to be able to manipulate it.

My app NFC.cool is using the object capture API and I fully developed the feature with an iPhone 13 Pro Max. On that phone everything works fine. No I have a new iPhone 15 Pro Max and I get crashes when the photogrammetry session is at around 1%. This happens when I completed all three scan passes. When I prematurely end a scan with around 10 images the reconstruction runs fine and I get a 3D model. com.apple.corephotogrammetry.tracking:0 (40): EXC_BAD_ACCESS (code=1, address=0x0) Any one else seeing these crashes?

I am building a mobile app that requires 3D scanning functionality. The app should be able to create an accurate scan of a small object using TrueDepth and convert that scan to STL geometric mesh file format. The required functionality is: 3D scan functionality using TrueDepth front facing sensor on an iPad The user should be able to view the scan as it's being generated The scan should be processed to eliminate bumps & holes No texture or colors. The output should be a 3D mesh. Scan resolution under 2mm The user can view, rotate and zoom in on the completed scan The user can save and load past scans Export to stl and ply file formats I have found some SDKs that offer this functionality but they are too expensive. Is it possible to scan and export files with ARKit, RealityKit, or other Apple libraries?

Hello! I have a question about usage snapshots from ios17 sample app on macOS 14. I tried to export folders "Photos" and "Snapshots" captured from ios and then wrote like: let checkpointDirectoryPath = "/path/to/the/Snapshots/" let checkpointDirectoryURL = URL(fileURLWithPath: checkpointDirectoryPath, isDirectory: true) if #available(macOS 14.0, *) { configuration.checkpointDirectory = checkpointDirectoryURL } else { // Fallback on earlier versions } But I didn't notice any speed or performance improvements. It looks like "Snapshots" folder was simply ignored. Please advise what I can do so that "Snapshots" folder is affected during calculations.

I want to create a 3D model with Photogrammetry Session. It's working fine with AVCaptureSession with Depth Data . But I want to capture a series of frames from ARKit and sceneDepth which is of type ARDepthMap. Depthdata is being stored as tiff but I'm still getting the error . if let depthData = self.arView?.session.currentFrame?.sceneDepth?.depthMap { if let colorSpace = CGColorSpace(name: CGColorSpace.linearGray) { let depthImage = CIImage( cvImageBuffer: depthData,options: [ .auxiliaryDisparity: true ,.auxiliaryDepth : true] ) depthMapData = context.tiffRepresentation(of: depthImage,format: .Lf, colorSpace: colorSpace, options: [.disparityImage: depthImage]) } } if let image = self.arView?.session.currentFrame?.capturedImage { if let imageData = self.convertPixelBufferToHighQualityJPEG(pixelBuffer: image) { self.addCapture(Capture(id: photoId, photoData: imageData, photoPixelBuffer: image,depthData: depthMapData)) } }` "No Auxiliary Depth Data found" while running the photogrammetry session.

In ARKit, I took few Color CVPixelBuffers and Depth CVPixelBuffers, ran PhotogrammetrySession with PhotogrammetrySamples. In my service, precise real scale is important, so I tried to figure out what is related to the rate of real scale model created. I did some experiments, and I set same number of images(10 pics), same object, same shot angles, distance to object(30cm, 50cm, 100cm). But even with above same controlled variables, sometimes, it generate real scale, and sometimes not. Because I couldn't get to source code of photogrammetry and how it work inside, I wonder do I miss and how can I create real scale every time if it's possible.

Anybody has noticed pivot issue in constructed model through object capture. Ideally pivot of object should be centre of bounding box but with new macOS changes now pivot is at 0,0,0 (below the bounding box) Here is a quick comparison Old v/s new

Hey There, I recently tried out the iOS 17 photogrammetry sample app, The results are very promising when compared to the iOS 16 apps The real world scale retention works amazing. However, my use case involves making the camera still and rotating the object instead, which was an option in iOS 16 but unfortunately removed in iOS 17 I wonder if there's a way to do so in iOS 17 app!

Hi, We are searching a solution to create 3D models in real life size using reflex cameras. We created an app for mac called Smart Capture that is using Object Capture to recreate 3D models from pictures. We used this project to digitize 5000 archeological findings of the Archaeological Park of Pompeii. We created a strong workflow using Orbitvu automated photography boxes with 3 reflex cameras for each box to speed up the capture process that allowed us to get a 3D model in less than 10 minutes (2-3 minutes to capture and about 7-8 minutes to process on a m2 max). The problem is that the resulting object has no size information and we have to manually take measurement and resize the 3d model accordingly, introducing a manual step and a possible error on the workflow. I was wondering if it's possible, using iOS 17 Object Capture APIs to get point cloud data which I could add to the reflex cameras pictures and process the whole package on the mac to retrieve the size of the real object. As far as I understood the only way to get it working before iOS 17 was to use depth information (I tried Sample Capture project), but the problem is that we have to work with small objects up to huge objects (our range is objects from about 1 to 25 inches) Do you have any clue on how to achieve this?

Is it possible to capture only manually (automatic off) on object capture api ? And can I proceed to capturing stage right a way? Only Object Capture API captures real scale object. Using AVFoundation or ARKit, I've tried using lidar capturing HEVC or create PhotogrammetrySample, It doesn't create real scale object. I think, during object capture api, it catches point cloud, intrinsic parameter, and it help mesh to be in real scale. Does anyone knows 'Object Capture With only manual capturing' or 'Capturing using AVFoundation for real scale mesh'

Value of type 'ObjectCaptureSession' has no member '$feedback' Value of type 'ObjectCaptureSession' has no member '$state' Any thoughts? code is how it came in the .zip

I used ObjectCaptureView with an ObjectCaptureSession in different setups, for example nested in an UIViewController so that I was able to deallocate the View and the Session after switching to another View. If I am going to use an ARSession with ARWorldTracking and SceneUnderstanding afterwards and the app won't show the overlaying Mesh anymore. Using SceneUnderstanding without opening the ObjectCaptureView previously works fine. Has someone faced the same issue, or how could I report this to apple? Seems like a problem with the ObjectCaptureView/Session itself. During the start of the ObjectCaptureSession the are also some logs in the Metadata telling me: "Wasn't able to pop ARFrame and Cameraframe at the same time", it will be shown like 10 or 15 times for every start. So I nested it in an ARSCNView but that didn't fixed it.

The Object Capture Apple sample code crashes while generating the 3D model when using more than 10 images. The code was running fine in Xcode beta 4 (and the corresponding iOS version). Since beta 5 I get these crashes. When scanning with exactly 10 images the process runs through fine. Does anybody know a workaround for that?

Generic struct 'ObservedObject' requires that 'ObjectCaptureSession' conform to 'ObservableObject Saw twitter posts that the Object capture is working in some groups. So how to handle these.

Hello, after installing Xcode 15 beta and the sample project provided for object capture in wwdc23 I am getting the below error: dyld[2006]: Symbol not found: _$s19_RealityKit_SwiftUI20ObjectCaptureSessionC7Combine010ObservableE0AAMc Referenced from: <35FD44C0-6001-325E-9F2A-016AF906B269> /private/var/containers/Bundle/Application/776635FF-FDD4-4DE1-B710-FC5F27D70D4F/GuidedCapture.app/GuidedCapture Expected in: <6A96F77C-1BEB-3925-B370-266184BF844F> /System/Library/Frameworks/_RealityKit_SwiftUI.framework/_RealityKit_SwiftUI I am trying to run the sample project on an iPhone 12 Pro (iOS 17.0 (21A5291j)) Any help in solving this issue would be appreciated.

Hi! My team has been playing with Object Capture on Mac for a while, and now that we got our hands on a MacBook Pro M2, we are starting to see differences between running the API on a Mac M1 and a Mac M2. The major difference observed is that on the M2 outputs, the object is correctly rotated, normal to the ground, while M1 outputs may have random rotations. This has been observed on latest Ventura 13.5.1 on the following machines: MacBook Pro M2 Pro 32Go MacBook Air M1 8Go and Mac mini 8Go. We have tested using both the PhotoCatch application and the HelloPhotogrammetry example (even using the same compiled binary). For sure we use the same options and same files on both sides. Is this expected behavior ? We would appreciate having the same rotation on both side. Regards

Running on iOS17 Beta 6 and getting the below issue. Conformance of 'ObjectCaptureSession.CaptureState' to protocol 'Equatable' was already stated in the type's module '_RealityKit_SwiftUI' Operator function '==' will not be used to satisfy the conformance to 'Equatable' 'ObjectCaptureSession.CaptureState' declares conformance to protocol 'Equatable' here Please help!
