EasyAR_稀疏空间图

EasyAR4.6.3 丨 Unity2020.3.15f2

1.创建稀疏空间地图

在EasyAR开发中心后台创建Scene许可证密钥，并且使用稀疏空间地图

2.设置稀疏空间地图库名，对稀疏空间地图进行管理，设置密钥

3.复制密钥到Unity中

添加Spatial Map AppId

添加APIKey & API Secret

4.Build Sparse Spatial Map

1. MainCamera 设置为 Solid Color

编写代码，扫描保存Sparse Spatial Map,上传到云端

    private ARSession session;
    private SparseSpatialMapWorkerFrameFilter mapWorker;
    public TextMeshProUGUI uiText;
    public TextMeshProUGUI btnText;
    public Button btnSave;

    private void Start()
    {
        session = FindObjectOfType<ARSession>();
        mapWorker = FindObjectOfType<SparseSpatialMapWorkerFrameFilter>();
        btnText.text = "Build Map";
        btnSave.onClick.AddListener(SaveMap);
    }

    private void SaveMap()
    {
        mapWorker.BuilderMapController.Host("EasyARScene01",null);
        uiText.text = "Start Build Map";
    }

在EasyAR开发中心查看存储的Spatial Map

设置横屏竖屏的效果

Portrait 竖屏
Portrait 竖屏，手机倒着
Landscape Right 横屏，屏幕在home键右侧
Landscape Left 横屏，屏幕在home键左侧
Auto Rotation 自动旋转屏幕

5.Read Sparse Spatial Map

通过远端Spatial Map库中将ID和Name赋值到其中

稀疏地图会保留存储地图的稀疏图的空间位置，并不会保存模型数据，记录的之前保存的Sparse Spatial Map的信息位置数据

编写代码，读取远程的SpriteMap

    private ARSession session;
    private SparseSpatialMapWorkerFrameFilter mapWorker;
    public TextMeshProUGUI uiText;
    public TextMeshProUGUI btnText;
    private Button btnSave;

    private void Start()
    {
        session = FindObjectOfType<ARSession>();
        mapWorker = FindObjectOfType<SparseSpatialMapWorkerFrameFilter>();
        btnSave = FindObjectOfType<Button>();
        btnText.text = "Read Map";
        btnSave.onClick.AddListener(ReadMap);
    }

    private void ReadMap()
    {
        mapWorker.Localizer.startLocalization();
        uiText.text = "Start Read Map";
    }
