如何在 ARCore Android 中禁用表面检测 [英] How to disable surface detection in ARCore Android

问题描述

我正在处理一个项目，但遇到了 ARCore 问题.我在我的项目中使用了 ARCore Location，我使用纬度和经度设置了对象的位置.但是当我在设备中看到它时，对象位置在 AR 中有所不同.

I am working on a project and facing an issue with ARCore. I used ARCore Location in my project, I set the location of object using latitude and longitude. but when I see it in the device, object location varies in AR.

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

    // When you build a Renderable, Sceneform loads its resources in the background while returning
    // a CompletableFuture. Call thenAccept(), handle(), or check isDone() before calling get().
    CompletableFuture<ModelRenderable> andy = ModelRenderable.builder()
            .setSource(this, R.raw.andy)
            .build();


    CompletableFuture.allOf(
            exampleLayout,
            andy)
            .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) {
                            DemoUtils.displayError(this, "Unable to load renderables", throwable);
                            return null;
                        }

                        try {
                            exampleLayoutRenderable = exampleLayout.get();
                            andyRenderable = andy.get();
                            hasFinishedLoading = true;

                        } catch (InterruptedException | ExecutionException ex) {
                            DemoUtils.displayError(this, "Unable to load renderables", ex);
                        }

                        return null;
                    });

    // Set an update listener on the Scene that will hide the loading message once a Plane is
    // detected.
    arSceneView
            .getScene()
            .setOnUpdateListener(
                    frameTime -> {
                        if (!hasFinishedLoading) {
                            return;
                        }

                        if (locationScene == null) {
                            // If our locationScene object hasn't been setup yet, this is a good time to do it
                            // We know that here, the AR components have been initiated.
                            locationScene = new LocationScene(this, this, arSceneView);

                            // Now lets create our location markers.
                            // First, a layout
                            LocationMarker layoutLocationMarker = new LocationMarker(
                                    77.398151,
                                    28.540926,
                                    getExampleView()
                            );

                            // An example "onRender" event, called every frame
                            // Updates the layout with the markers distance
                            layoutLocationMarker.setRenderEvent(new LocationNodeRender() {
                                @SuppressLint("SetTextI18n")
                                @Override
                                public void render(LocationNode node) {
                                    View eView = exampleLayoutRenderable.getView();
                                    TextView distanceTextView = eView.findViewById(R.id.textView2);
                                    distanceTextView.setText(node.getDistance() + "M");
                                }
                            });
                            // Adding the marker
                            locationScene.mLocationMarkers.add(layoutLocationMarker);

                            // Adding a simple location marker of a 3D model
                            locationScene.mLocationMarkers.add(
                                    new LocationMarker(
                                            77.398151,
                                            28.540926,
                                            getAndy()));
                        }

                        Frame frame = arSceneView.getArFrame();
                        if (frame == null) {
                            return;
                        }

                        if (frame.getCamera().getTrackingState() != TrackingState.TRACKING) {
                            return;
                        }

                        if (locationScene != null) {
                            locationScene.processFrame(frame);
                        }

                        if (loadingMessageSnackbar != null) {
                            for (Plane plane : frame.getUpdatedTrackables(Plane.class)) {
                                if (plane.getTrackingState() == TrackingState.TRACKING) {
                                    hideLoadingMessage();
                                }
                            }
                        }
                    });


    // Lastly request CAMERA & fine location permission which is required by ARCore-Location.
    ARLocationPermissionHelper.requestPermission(this);

这里的主要问题是它检测表面并根据它放置图像，如果有可能禁用表面检测，那么它可以完美地工作.

The major problem in this is that it detects surface and place image according to that, If there is any possibility to disable surface detection in this then it works perfectly.

推荐答案

使用 EnablePlaneFinding = false 修改会话配置，然后禁用并重新启用 ARCoreSession.这将禁用平面查找，但会保持现有平面的当前状态.

Modify the session configuration with EnablePlaneFinding = false and then disable and reenable the ARCoreSession. That would disable plane finding but would keep existing planes as they were at the moment.

如果您不想禁用会话，您可以在不禁用会话的情况下强制对会话进行 OnEnable() 调用:

If you don't want to disable the session you could force an OnEnable() call on the session without disabling it:

 var session = GameObject.Find("ARCore Device").GetComponent<ARCoreSession>(); 
session.SessionConfig.EnablePlaneFinding = false; session.OnEnable();
