最新高通 Vuforia 7.0.47 版本-对应API-动态加载、卸载识别库-闪光灯-对焦-翻转摄像头-动态更改识别数量等

整理了下Vuforia 7 版本对应识别功能的函数 基本上和6版本无差异

Vuforia版本获取

       string vuforiaVersion = Vuforia.VuforiaUnity.GetVuforiaLibraryVersion();
       string unityVersion = UnityEngine.Application.unityVersion;
       UnityEngine.Debug.Log("Vuforia " + vuforiaVersion + "\nUnity " + unityVersion);

控制vuforia摄像机对应的Texture渲染

         VuforiaRenderer.Instance.Pause(true);//关闭渲染 参数false开始渲染

• TrackableSettings类主要功能

  • 开启扩展追踪

  • 获取当前激活识别库名称列表

  • 激活指定的识别数据集

  • 关闭指定识别数据集

  • 动态载入识别数据集

  • 卸载所有识别数据集（识别库）

  • 设置同时识别Image的个数

  • 设置同时识别3D物体的个数

• InitErrorHandlers类主要功能

  • Vuforia初始化时对应错误的回调(CustomLog自己封装的)

代码块如下：

        }
    }
