I am trying to make this to work but after building the command line app, I kept getting error when running https://developer.apple.com/documentation/realitykit/creating_a_photogrammetry_command-line_app
I am using MacBook-Air 2017 and Xcode 13.0 beta 4,
Example error:

I have a question about Object Capture, a new API from Apple. I have created 3D models of a sofa, shoes and a bag using HelloPhotogrametory, a sample command line application. Only the sofa has a 3D model of the floor as well. Is there a way to avoid generating a 3D model of the floor?
The photos used are HEIC, the number of photos is about 50, and the runtime option is the default of the sample.

Is there any way to avoid creating 3D models of these objects? Or do you have any information about the limit size of these objects that do not create 3D models of them?

I'm trying to gather some depth data in order to send off to Object Capture for processing. What depth file formats are supported? I can see from the capture sample code they are written in 32bit tiff grayscale converting depth to disparity. Are there any other formats supported? Unfortunately the documentation is very light on this. Do you know if 16bit png would be supported?
Some more detail on this would go a long way, thank you.

My name is Daria. I represent a students team from Omsk, Russia.
After WWDC21 we've decided to experiment with the Object Capture technology to reconstruct histrorical museum objects and place it as an art exhibition nearby the museum.
We've talked with different museums. Our idea was supported by Vrubel museum (http://vrubel.ru). They provided us access to their historical sculptures (dated by 19th century).
The following are reconstructed models, that we created with Object Capture technology:
Young Woman
Psyche
Psyche with a butterfly
Cupid's head
Silvio
Deer with a branch
All together, we created the unique experience that available through iOS app to any peson walking around the museum.
Video recording of the experience
We would be glad to hear any feedback from Apple and scale our experiment to other museums!

Hi,
I am trying to build and run the HelloPhotogrammetry command line app that I have downloaded from here.
When I run the app, I get the following error:
Error creating session: cantCreateSession("A GPU that is not in low power mode is required. https://developer.apple.com/documentation/metal/mtldevice/1433409-lowpower")
Does this app require a Mac with a dedicated GPU? or can I somehow use my Macbook pro with an integrated GPU to run it?
"Creating 3D models with Object Capture" the API provided is only working on console app now ?
It's working perfect on console app but not on macOS GUI app.
I couldn't find such information in the documents as well.
In my GUI app, I am getting the error as, "Process got error: invalidRequest(RealityFoundation.PhotogrammetrySession.Request.modelFile(url: file:///Users/s***ik/Desktop/Pot_usdz/sam.usdz, detail: RealityFoundation.PhotogrammetrySession.Request.Detail.preview, geometry: nil), ".modelFile directory path file:///Users/snayvik/Desktop/Pot_usdz/ cannot be written to!")"
Any help is appreciated.

Hey,
I have my working photogrammetry command line app. Plz help me embedding this app into my other macOS GUI app. I have completed my GUI app, just need to connect both the apps.
What is the appropriate way ?
Hi,
Is it possible to create a 3D model by ingesting a video ? As we create by using pictures ?
Is there any API provided by apple for this ?
Any help is appreciated.
Thanks

Hi,
I am trying to build and run the HelloPhotogrammetry app that is associated with WWDC21 session 10076 (available for download here).
But when I run the app, I get the following error message:
A GPU with supportsRaytracing is required
I have a Mac Pro (2019) with an AMD Radeon Pro 580X 8 GB graphics card and 96 GB RAM. According to the requirements slide in the WWDC session, this should be sufficient. Is this a configuration issue or do I actually need a different graphics card (and if so, which one?).
Thanks in advance.

As for the subject, CaptureSample App doesn't get depth data on iPhone12 Pro Max.
I mean, the app reports that we correctly have depth data and photos captured are shown with depth data green badge attached but generated .tif files are always a full white file, no more details.
Is there something i'm missing? Do i need to do something more to enable depth data acquisition?
I'm taking pictures of objects no more distant than 50 cm
I work in the thoroughbred industry. I am interested in capturing a 3D model of a racehorse (at rest) to later use in a dataset for analysis.
A recent paper (see "Body measurement of riding horses with a versatile tablet-type 3D scanning device") used the iPhnoe 12, a commerical app (Scandy) and LiDAR to create 3D models of the horse. It reads as a fairly straightfoward process, however I was wondering if there was any benefit to using Object Capture over LiDAR. It would seem as easy to walk around the horse and capture a video and then create the process to extract frames from the video for Object Capture?
In terms of creating 3D models, is one method better/more accurate than another?

What do you mean by "start by creating a session?" I'm an architect(building designer) and a novice programmer trying to learn to use the tools to help in my design process. But I'm kinda stuck in trying to start the engine, let alone drive it. Any advice would be helpful!

I'm on Mac OS 12 (Monterey) and Xcode 13 but it still get the error "Cannot find type 'PhotogrammetrySession' in scope"
I tried restarting Xcode, tried restarting the Mac. But I still get the error. I have imported "RealityKit".
I'm trying to run the HelloPhotogrammetry code provided by Apple.

Hi!
I'm really excited to try the new ObjectCapture API. I have a iPhone 12 Pro (with the lidar) but have a old MacBook. I'm planning to get a new MacBook to run the RealityKit and Photogrammetry software, as given in this example: https://developer.apple.com/videos/play/wwdc2021/10076/.
Are there any restrictions on the Mac hardware or is it fine as long as they support macOS 12.0+ Beta and Xcode 13.0+?
Thanks!

I took photos of Nick shoes on the side of CaptureSample of WWDC2021. The initial position of the final generated Nick shoes is upside down. How do I position the initial position of the model as forward

Hello, I am trying to get the object capture command line example program working, but I am running into a weird error. "Cannot find 'PhotogrammetrySession' in scope." I am running xcode 13, and I am on MacOS 12.0 Beta (21A5522h). From what I have seen online this error only occurs when attempting to use object capture on an older version of MacOS. I am probably over looking something obvious, but I would appreciate any help.
The object capture command line program example: (https://developer.apple.com/documentation/realitykit/creating_a_photogrammetry_command-line_app)

Any images or PhotogrammetrySamples after 1000 will be rejected and ignored. This is regardless of image resolution, bit depth, and format.
This restriction is still present in macOS 12.0.1. Please remove this restriction.
