我正在尝试使用Apple的教程创建一个USDZ对象从照片创建三维对象。我在这个示例项目中使用了新的摄影测量会话：摄影测量命令行应用程序。
这就是代码：
let inputFolderUrl = URL(fileURLWithPath: "/tmp/MyInputImages/")
let url = URL(fileURLWithPath: "MyObject.usdz")
var request = PhotogrammetrySession.Request.modelFile(url: url,
detail: .full)
guard let session = try PhotogrammetrySession(input: inputFolderUrl) else {
return
}
我得到以下错误：

tl；dr：尝试另一组图像，可能是您的图像有问题。
除了一个例子，我已经成功地让它工作了，我收到了和你一样的错误。我想出于某种原因，它不喜欢我为那个特定物体拍摄的那组照片。你可以试着只拍摄另一个简单物体的几张照片，然后再试一次，看看这是否是你第一次跑步的问题。
