使用 ARCORE 将图像放置在墙上

I want to place an image, on the wall with ARCore. The image is converted from a regular image view. I only detect vertical surfaces but when I place the image it is placed like this: I can not figure out how to transform in order to hang the image on the wall, just like in real life.

    AR fragment
    fragment = (ArFragment) 
    getSupportFragmentManager().findFragmentById(R.id.sceneform_fragment);

    CompletableFuture<ViewRenderable> imgView = ViewRenderable.builder()
            .setView(this, R.layout.textview)
            .build();

    CompletableFuture.allOf(imgView).handle((notUsed, throwable) -> {
        // When you build a Renderable, Sceneform loads its resources in the background while
        // returning a CompletableFuture. Call handle(), thenAccept(), or check isDone()
        // before calling get().

        if (throwable != null) {

            Log.d("MainActivity", "onCreate: " + "Unable to load renderable");
            return null;
        }

        try {

            imageViewRenderable = imgView.get();

        } catch (InterruptedException | ExecutionException ex) {
            Log.d("MainActivity", "onCreate: Unable to load renderable");

        }

        return null;
    });

    try {
        mArSession = new Session(this);
    } catch (UnavailableArcoreNotInstalledException e) {
        e.printStackTrace();
    } catch (UnavailableApkTooOldException e) {
        e.printStackTrace();
    } catch (UnavailableSdkTooOldException e) {
        e.printStackTrace();
    } catch (UnavailableDeviceNotCompatibleException e) {
        e.printStackTrace();
    }

    mArConfig = new Config(mArSession);
    mArConfig.setUpdateMode(Config.UpdateMode.LATEST_CAMERA_IMAGE);
    mArConfig.setPlaneFindingMode(Config.PlaneFindingMode.VERTICAL);
    mArSession.configure(mArConfig);

    fragment.getArSceneView().setupSession(mArSession);

    fragment.setOnTapArPlaneListener((HitResult hitresult, Plane plane, MotionEvent motionevent) -> {
                Anchor anchor = hitresult.createAnchor();
                AnchorNode anchorNode = new AnchorNode(anchor);

                anchorNode.setParent(fragment.getArSceneView().getScene());
                TransformableNode art = new TransformableNode(fragment.getTransformationSystem());
                art.setParent(anchorNode);
                art.setRenderable(imageViewRenderable);
                art.select();

                ImageView imageView = (ImageView)imageViewRenderable.getView();
                Picasso.get().load("http://www.cbk-enschede.nl/plaatjes/ens/jpg/GSA023.jpg").into(imageView);

            }
    );
