RealityKit - macOS摄影测量应用程序的误差

Question

在过去的几天里，我尝试用Xcode创建一个摄影测量命令行应用程序。但是，当我试图运行代码时，我一直收到一个错误。

我得到的错误如下：

[Photogrammetry] queueNextProcessingBatchIfNeeded(): Already running a job... not starting new one.

我在谷歌上搜索过，但我找不到任何经历过同样问题的人。

我使用的代码如下：

import Foundation
import RealityKit

let inputFolderUrl = URL(fileURLWithPath: "/Users/username/Desktop/AirForce", isDirectory: true)
let session = try! PhotogrammetrySession(input: inputFolderUrl, configuration: PhotogrammetrySession.Configuration())

try! session.process(requests: [.modelFile(url: URL(fileURLWithPath: "/Users/username/Desktop/MyModel.usdz"), detail: .preview)])

My system:

MacBook Air (M1,2020年)

macOS蒙特雷12.0.1 (21A559)

Xcode版本13.2.1 (13C100)

用我的密码。它起作用了。如果你需要更多有关摄影测量的细节，请阅读我的中型员额。

import Cocoa
import RealityKit

struct Photogrammetry {

    typealias Config = PhotogrammetrySession.Configuration
    typealias Request = PhotogrammetrySession.Request
    var inputFolder = "/Users/swift/Desktop/WildBoar"
    var outputFile = "/Users/swift/Desktop/wildBoar.usdz"
    var detail: Request.Detail = .medium

    fileprivate func running() {
        var config = PhotogrammetrySession.Configuration()
        config.featureSensitivity = .normal
        config.isObjectMaskingEnabled = true
        config.sampleOrdering = .unordered

        let inputFolderURL = URL(fileURLWithPath: inputFolder, 
                                     isDirectory: true)

        var optionalSession: PhotogrammetrySession? = nil

        do {
            optionalSession = try PhotogrammetrySession(
                                             input: inputFolderURL,
                                     configuration: config)        
        } catch {
            print("ERROR")
            Foundation.exit(1)
        }

        guard let session = optionalSession 
        else { Foundation.exit(1) }

        withExtendedLifetime(session) {
            do {
                let request = PhotogrammetrySession.Request
                   .modelFile(url: URL(fileURLWithPath: outputFile),
                           detail: detail)
                try session.process(requests: [request])
                RunLoop.main.run()
            } catch {
                print("ERROR")
                Foundation.exit(1)
            }
        }
    }
}

你好，我也有同样的问题，我通过添加一行来解决这个问题。RunLoop.main.run()

import Foundation
import RealityKit

let inputFolderURL =  URL(fileURLWithPath: "/Users/saibalaji/Desktop/ObjectCapture/ObjectCapture/Images/camera",isDirectory: true)
let outputURL = URL(fileURLWithPath: "/Users/saibalaji/Desktop/ObjectCapture/ObjectCapture/Camera.usdz")

let session = try! PhotogrammetrySession(input: inputFolderURL, configuration: PhotogrammetrySession.Configuration())
let request = PhotogrammetrySession.Request.modelFile(url: outputURL, detail: .medium)
try!  session.process(requests: [request])
        RunLoop.main.run()
