Question

我正在使用ARCore创建一个应用程序，但我不希望ARCore在应用程序启动时立即查找平面。相反，我想在我的应用程序中按下按钮时开始检测平面。如果我也可以停止指令上的飞机检测也会很棒。

有谁知道如何开始和停止命令的ARCore平面检测？

我正在Unity中构建应用程序。

提前非常感谢！

Answer 1

ARPlaneVisualizer.cs上的

，有这段代码

    void OnEnable()
    {

        m_PlaneLayer = LayerMask.NameToLayer ("ARGameObject");
        ARInterface.planeAdded += PlaneAddedHandler;
        ARInterface.planeUpdated += PlaneUpdatedHandler;
        ARInterface.planeRemoved += PlaneRemovedHandler;
        HidePlane(true);
    }

    void OnDisable()
    {
        ARInterface.planeAdded -= PlaneAddedHandler;
        ARInterface.planeUpdated -= PlaneUpdatedHandler;
        ARInterface.planeRemoved -= PlaneRemovedHandler;
        HidePlane(false);
    }

您可以使用OnEnable()代码作为开始跟踪和OnDisable()代码来停止跟踪。

最初创建bool来限制表面检测代码，并不满意地使bool变为true。

bool isSurfaceDetected = true;

if (isSurfaceDetected) {


            Session.GetTrackables<TrackedPlane> (_newPlanes, TrackableQueryFilter.New);

            // Iterate over planes found in this frame and instantiate corresponding GameObjects to visualize them.
            foreach (var curPlane in _newPlanes) {
                // Instantiate a plane visualization prefab and set it to track the new plane. The transform is set to
                // the origin with an identity rotation since the mesh for our prefab is updated in Unity World
                // coordinates.
                var planeObject = Instantiate (plane, Vector3.zero, Quaternion.identity,
                                      transform);
                planeObject.GetComponent<DetectedPlaneVisualizer> ().Initialize (curPlane);

                //              Debug.Log ("test....");

                // Apply a random color and grid rotation.
                //          planeObject.GetComponent<Renderer>().material.SetColor("_GridColor", new Color(Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f), Random.Range(0.0f, 1.0f)));
                //          planeObject.GetComponent<Renderer>().material.SetFloat("_UvRotation", Random.Range(0.0f, 360.0f));

                //

            }

在画布上创建一个停止按钮，然后在方法下方进行点击

public void StopTrack()
    {
        // Make isSurfaceDetected to false to disable plane detection code
        isSurfaceDetected = false;
        // Tag DetectedPlaneVisualizer prefab to Plane(or anything else)
        GameObject[] anyName = GameObject.FindGameObjectsWithTag ("Plane");
        // In DetectedPlaneVisualizer we have multiple polygons so we need to loop and diable DetectedPlaneVisualizer script attatched to that prefab.
        for (int i = 0; i < anyName.Length; i++) 
        {
            anyName[i].GetComponent<DetectedPlaneVisualizer> ().enabled = false;
        }

    }

确保停止按钮方法在ARController中
