Need help regarding Augmented Image about sceneview-android HOT 11 CLOSED

I was facing the same issue since there is no example code for this library yet. But here are some steps that might help you to start:

Get the ArScenView like the other examples show: ArScenView sceneView = view.findViewById<ArSceneView?>(R.id.sceneView); Then configure the image database in the configureSession-method of the sceneView like this:

// in your onViewCreated, after you setup the ArSceneView
sceneView.configureSession(this::initialiseSceneViewSession)

// ---

private fun initialiseSceneViewSession(session: ArSession, config: Config) {
       // other init stuff ....
       // init image database
       val imageDatabase = this.requireActivity().assets.open(TRACKED_IMAGE_DATABASE_PATH).use {
            AugmentedImageDatabase.deserialize(session, it)
        }
        config.augmentedImageDatabase = imageDatabase
        session.configure(config)
    }

Now you only need to connect to the onAugmentedImageUpdate callback of the scenView in order to be notified if an image is tracked.

// in your onViewCreated, after you configureSession
sceneView.onAugmentedImageUpdate = this::checkAugmentedImageUpdate

// ---

private fun checkAugmentedImageUpdate(augmentedImage: AugmentedImage) {
        Log.i(
            TAG, "Augmented image update ${augmentedImage.name} with " +
                    "tracking state ${augmentedImage.trackingState}"
        )
    }

The last important step is to anchor your model node at the center of that image. Therefore you can simply create an anchor from the center pose of the augmented image in the callback:

// in checkAugmentedImageUpdate, modelNode is a simple ArModelNode with an loaded 3d model
val anchorImage = augmentedImage.createAnchor(augmentedImage.centerPose)
modelNode.anchor = anchorImage
sceneView.addChild(modelNode)

Hope this helps you to get started ✌️

Override it in the res folder

Hi @Cardo, this code works for me:

sceneView.onAugmentedImageUpdate = mutableListOf(
    { augmentedImage ->
        if (augmentedImage.trackingState == TrackingState.TRACKING) {
            val anchorImage = augmentedImage.createAnchor(augmentedImage.centerPose)
            modelNode!!.anchor = anchorImage
            binding.sceneView.addChild(modelNode!!)
        }
    }
)

Thanks a lot @LukasPoque .. I'll try it for sure.

How do I modify the "scenview_fit_to_scan" image?

Hi @LukasPoque, the checkAugmentedImageUpdate function on the example gives me an error of wrong type (as in type mismatch with MutableList<(AugmentedImage -> Unit)> required). Any clue on how this checkAugmentedImageUpdate function should be formed? Thanks in advance.
