Unity3d 错误-无法启动AR跟踪请检查您是否有摄像头连接错误

我不确定哪个回购协议是记录此错误的正确位置- 你好,

我刚刚开始AR/VR领域的开发，并与Unity一起使用ARToolkit。我用hiro创建了最简单的AR跟踪器。 每当我运行projet时，它都会被上面的标题错误卡住-

这是控制台，详细说明了错误-

代码似乎找不到camera_para.dat。我在我的AR文件夹中找到这个，不确定是否正确

你能从这里运行示例场景吗：

Assets/ARToolKit5 Unity/example Scenes/SimpleScene

？你能给我一个Unity Inspector窗口中

ARToolKit/AR控制器/视频选项的屏幕截图吗。您确信硬件的驱动程序是最新的，并且功能正常吗？你也可以尝试其他软件来确认这一点，比如
Skype
。大家好。我用的是l；aptop正面，有问题吗？此外，AR toolkit中的示例应用程序也不起作用。仅供参考，将其导出到APK在我的手机上也不起作用phone@KaushikRay在这种情况下，最有可能是您的设置。您拥有的
Unity
和
ARToolKit
的版本是什么？尝试升级到最新版本。您的正面是否正常工作（不，这对AR来说不是问题）？你能从这里运行示例场景吗：
