HelloPhotogrammetry 重建失败错误

Question

我正在尝试使用 Apple 的教程创建一个 USDZ 对象 Creating 3D Objects from Photographs. I'm using the new PhotogrammetrySession within this sample project: Photogrammetry Command-Line App.

这是代码：

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      }

我收到以下错误：

我使用的是装有 macOS Monterey 12.0 Beta (21A5248p) 和 Xcode 13.0 beta (13A5154h) 的 M1 iMac。

Answer 1

tl;dr: 试试另一组图片，可能你这组图片有问题。

除了在一个实例中，我已经成功地运行了它，并且我收到了与您遇到的相同的错误。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。您可以尝试只拍几张另一个简单物体的照片，然后再试一次，看看您的第一个运行.
