ARFoundation ImageTracking Sample scene doesnt generate image database

    I'm trying to get the sample scene from the official github repo of ARFoundation 2.1 to work, but it doesnt generate the image database. The apk is working though and a camera feed can be seen on the display.

    The error codes:

    Failed to generated ARCore reference image library 'ReferenceImageLibrary'
    UnityEngine.GUIUtility:processEvent(Int32, IntPtr)

    BuildFailedException: Failed to generate image database. Output from arcoreimg:

    stdout:

    I'm using Unity 2019.1.0f2 on Windows 7, all packages, sdk's etc should be installed. My target is a Samsung Galaxy Tab S4 with Android 9, although that shouldn't matter here.

    Actually tried the same thing on a different PC with Windows 10 and Unity 2019.1.3f1, same problem. I guess I'm missing some packages? I'm really clueless.

    (On a side note: Build and run doesnt work for me either with ARFoundation, but I guess that's another story on its own).

    Does anyone have a solution for my problem? I'm tired of working on ARKit and ARCore simultanously and would really like to utilize ARFoundation. Thanks.

    edit: attached a picture of my packege manager window.

    I use ARFoundation 2.10 with ARKit 2.10, iPhone XS, and I found that other ARFoundation features work correctly, but ARTrackedImageManager doesn't work. I tested it in both empty project and sample project on GitHub.

    I guess we need to wait for a hotfix.

    The issue has to do with how the image width is translated to a string. Depending on your region settings, it could be something like "0.25" or "0,25" (comma vs period). The ARCore image library generation tool expects a period. A fix is coming soon. In the meantime, you can try modifying the ReferenceImageLibrary to not specify widths for the images. (Note, this will only work on ARCore as ARKit requires widths for all images.)

    Any hints on how to do that? Just ticking off "Specify size" on the image doesn't seem to help (Unity 2019.2b with ARCore 2.1 und AR Foundation 2.1), I am still getting the build error mentioned above when trying to build an apk.

    I would gladly provide the contents of that .txt-file, but I cant find it in the given directory (even after building it again). I assume it's deleted or moved to another directory? Any pointers on how to save the error file in the building process? I couldn't find it in the documentation.

    I changed some unity console settings: "stack trace logging --> error" from "script only" to "full", which returned a different error for the first error message. Don't think it will be particularily useful, but I guess it won't hurt to post it.

    I'm also trying to get the image tracking to work on iOS but no luck yet. Using Unity 2019.2b04 and the latest ARFoundation samples. Everything else works fine.

    Any hints @tdmowrer or @I_Jemin?

    If you get the same error code as me, would it be possible for you to provide the desired .txt-file (in my case: C:\Users\XXX\AppData\Local\Temp\4d676c83db4046c2bd0d68b010cd84ef\39344433fd8c4712b4ee109a5c73a2b2.txt) ?

    Apparently he misses some information to help us with that issue.

    @PTW_AR I'm on iOS and I get no error at all. It simply doesn't recognize any images.

    I don't think that's the right place for your problem. Anyway, I will give it a try:

    You will need iOS 13 and XCode 11 in order to get it onto your iOS-device. I'm working with a Android device right now, so I haven't used XCode yet.

    the solution to my problem is update ARfoundation to 2.2.0 but do not update ARkit XR 2.2.0, I did downgrade to ARKit to 2.1.0 and after that everything worked!

    Also doesn't work if .PNG extension is in CAPS. Changes to lowercase and now it seems to build.

    For ARCore or ARKit or both?

    Edit: I tested building both ARCore and ARKit from a Mac and they both complain that .PNG is not a valid extension. ARKit still recognizes the image at runtime, so it appears safe to ignore the Xcode warning. ARCore, however, will not generate the image database at all. I see what we can do in ARFoundation to work around this limitation.

    Apologies; I missed your plea for help. If you're still having issues, please let me know the exact version of Unity, ARFoundation package, ARKit XR Plugin package, iOS, and Xcode.

    Make sure your image target is at least 300 x 300 pixels. The file extension should be .png preferably. If it is .jpeg avoid heavy compression for best performance.

    It's happened due to the low-quality score of the image. ARCore reference image library accepts images of type .png and .jpg only. Also, It shows to have a quality score.
    First, we have to check the quality score of the image using arcoreimg tool
    We can download it from https://raw.githubusercontent.com/g.../master/tools/arcoreimg/windows/arcoreimg.exe
    Refer the following link to check the quality score https://developers.google.com/ar/develop/c/augmented-images/arcoreimg
    If the quality score is greater than 10 then you can create a database using that image
    otherwise, try another one.

    It's happened due to the low-quality score of the image. ARCore reference image library accepts images of type .png and .jpg only. Also, It shows to have a quality score.
    First, we have to check the quality score of the image using arcoreimg tool
    We can download it from https://raw.githubusercontent.com/g.../master/tools/arcoreimg/windows/arcoreimg.exe
    Refer the following link to check the quality score https://developers.google.com/ar/develop/c/augmented-images/arcoreimg
    If the quality score is greater than 10 then you can create a database using that image
    otherwise, try another one.

    Guys the solution is to fixing the size of your produced image it must be width x hight =
    equal to integer not float number! Try to do this!

    Fixed by changing the image I had added to my 'ReferenceImageLibrary' for a qr code to test it. Im assuming not enough detail on the first image, idk, qr code worked fine.

    This was the error I was getting when trying to build and run for android:
    -Failed to generated ARCore reference image library 'ReferenceImageLibrary' ...
    -BuildFailedException: Failed to generate image database. Output from arcoreimg: ...

    These are the versions I was using:
    -AR Foundation3.0.1
    -AR Sybsystems 3.0.2
    -ARCore XR Plugin 3.0.1

    I have been doing some tests with several images, my closest guess thus far is that the photo should not have very deep blacks, otherwise it causes error.

    Im using unity 2019.4.1f0 LTS.

    Maybe give it shot

    Hi, ARKit now offers
    var automaticImageScaleEstimationEnabled: Bool
    in its ARWorldTrackingConfiguration
    Can we/is it possible to enable this to allow us to set the image size, for variable sized tracking images?
    Thanks.
