Hello, I'm creating an app that use PhotogrammetrySession Class to build 3D objects from photographs (https://developer.apple.com/documentation/realitykit/creating-3d-objects-from-photographs). I'm wondering why this class is working only on Pro iphone (12 Pro, 13 Pro, 14 Pro, 15 Pro and 16 Pro) and none non-Pro iPhone. My app does not use Lidar so it's not the problem. I thought it could be power-related but a18 soc from iPhone 16 is more powerful than a14 bionic from iPhone 12 Pro (i could also mention iPhone 13 Pro and iPhone 14 that both have a15 bionic whereas only the first one is compatible). Did I miss something that could explain these restrictions ? Is there any plan to make this class usable by every iPhone enough powerful to run it ? Thanks in advance for answering me

We are currently using Apple's Object capture module and wonder if it would be possible to collect the following data : Device information Current translation / rotation Focal length embedded to the image headers GPS localisation information. Information about the exposure time White balances and the color correction matrices We also have 2 additional questions : Is there an option to block close up accomodation of the camera ? Is there a way for the object capture module to take a video instead of a series of picture ?

I've experimented quite a bit with the new API designed to neutralize image colors using the iPhone flash, and I think the concept is brilliant. The flash could potentially serve as a substitute for a color checker, given our full control over it. However, I believe there are several areas where this API could be improved. Firstly, the resulting images often appear "unattractive"—colors tend to look faded, and the images themselves can be overly bright and washed out, losing the natural ambiance, shadows, and introducing unwanted flash reflections. There is also inconsistency in color rendering; for example, yellows sometimes appear unnatural, possibly due to reflections. In some cases, all the colors in the image are completely desaturated or become black and white if another light source does not fully illuminate the scene. Additionally, the shadows cast by the flash don't correct the colors properly since they fall outside the flash's range. I think many of these issues could be resolved if we had access to ProRAW images capturing both the ambient light (without flash) and the flash-illuminated scene. With these, we could use specific colors in the image as a reference, similar to a color checker, to create an ICC profile or color transformation matrix to adjust the image colors more globally. This approach could help retain the shadows from the ambient light while still correcting colors to a neutral tone. Access to ProRAW data is crucial for this, as it would provide images without the saturation issues that can affect some colors and with a linear tone curve. I hope this suggestion makes sense and could help improve the API's effectiveness.

I have updated the sample code so that the scan will start generating when 15 photos r captured. I hope I can catch this error so the app wont crash.... really need help on this and thank you in advanced !

Create 3D models with Object Capture VS Create 3D models with MAC 1.After testing the model generated by the pictures taken on the mobile phone and comparing the .raw progress generated by the same set of data on the MAC side, the highest accuracy model has different effects. Sometimes the mobile phone model has higher accuracy, and sometimes the MAC model has higher accuracy. What are the two ends? The difference is that according to WWDC2023 MAC, a higher-precision model can be generated. However, in actual testing, it is possible that the integrity of MAC generation is not as good as that of the mobile phone. This is why. 2.Is it possible to set the accuracy of the generated model on the mobile phone?

Is it possible to create a roomplan with the texture of a room plan's wall - or some way to combine ObjectCapture results with RoomPlan results?

Is it possible to both capture the images required for ObjectCapture and the scan data required to create an ARObjectAnchor (and be able to align the two to each other)? Perhaps an extension of this WWDC 2020 example that also integrates usdz object capture (instead of just import external one)? https://developer.apple.com/documentation/arkit/arkit_in_ios/content_anchors/scanning_and_detecting_3d_objects?changes=_2

Hello :) As title, I have used RCP with reference objects to capture items in real world. My next step is to detect how close the user finger is that object. I had tried to get the entity's relative position to root but found the position, somehow, is always the same regardless of how and where I move around the camera or the object. The entity has a child transform with a collision component, which is used to detect collision when the finger is closed enough to calculate the distance, but it fails as well... Any help will be appreciated, ty

The 3D object capture feature doesn’t seem to work on my iphone 12 pro. The circle that is supposed to show up when you begin to begin to move around the object doesnt show up so object capture doesn’t even begin. It says ‘more light..’ or ‘move closer’ but this doesnt happen on my iphone 14 pro. Works perfectly fine on that even with the same lighting. How can this be fixed?

I'm working on training an object tracking model in CreateML for visionOS that has fan blades on it and looking to try to train while ignoring a section of the geometry. When I train currently, it can detect the object if the fan blades are in the same orientation as when scanned but if they move it struggles. I see there is an "objects to avoid" data source that can be added but upon reading the description, I don't think it does what I'm needing but I could be wrong. Is there anyway to have the training ignore a part of the geometry that has a significant effect on the silhouette of the object?

Hi everyone, I'm working with Core ML for object tracking and have successfully trained a couple of models. However, when I try to use the reference object file in the object tracking sample code from the WWDC video, it doesn't work. I'm training the model on a single-color plastic spherical object. Could this be the reason for the issue? I also attempted to use USDZ 3D assets that resemble the real object. Do these need to be trained with the Object Capture app to work properly? Speaking of the Object Capture app, my experience hasn't been great. When I scanned my spherical object, the result was far from a sphere—it looked more like a mushy dough. Any insights or suggestions would be greatly appreciated!

Hi, Object Capture's original sample code was released last year, and this year there was a talk about adding area mode to it. The talk links to the old Object Capture code - when can I expect to have the new one with area mode, and is there anything I can help you with to have it published faster? Thanks!

I would like to enable users of my iOS app to place an object they want to scan, for example, on a turntable, instead of walking around it, in order to generate a 3D model of it afterward. How can I achieve this with the Object Capture API?

Hy my name is zubair and i a blogger. I have recently create a website on gold price in oman url omangoldprices.com I maked a well design header footer and every thing as compared with my competitors but the header of my website disabled and not working on Macbook and macbook pro and the logo does not showing on IOS version Iphone 6 12.6.1. I am very comfused about that can anyone help me in?

Im trying to take an object capture, and scale it. What I did so far is create a Reality Composer project, insert the .objcap file into the project, and then scaled it from 100%, to 200%. I then extracted it as a USDZ. it just won't show up in the Xcode preview now, and im not sure why it doesn't show. Is there any way to fix this? im going crazy trying to find a fix for this to work.

Hi everyone, is it possible to use a 3D USDZ file to train a model in Create ML, I see there is an image option but it would be good to use these files from Reality Composer from object capture? Or is this in the works for forthcoming Xcode updates? Many Thanks Stuart

Hello, I'm currently building an app that implements the on-device object capture API to create 3D models. I have two concerns that I cannot find addressed anywhere on the internet: Can on-device object capture be performed by devices without LiDAR? I understand that depth data is necessary for making scale-accurate models - if there is an option to disable it, where would one specify that in code? Can models be exported to .obj instead of .usdz? From WWDC2021 at 3:00 it is mentioned that it is possible with the Apple Silicon API but what about with on-device scanning? I would be very grateful if anyone is knowledgeable enough to provide some insight. Thank you so much!
