Saya mencoba mendapatkan data kedalaman dari kamera di iOS 11 dengan AVDepthData, ketika saya mengatur photoOutput dengan AVCapturePhotoCaptureDelegate, photo. depthData nihil.
Jadi saya mencoba mengatur AVCaptureDepthDataOutputDelegate dengan AVCaptureDepthDataOutput, tapi saya tidak tahu cara mengambil foto kedalaman?
Adakah yang pernah mendapatkan gambar dari AVDepthData?
Sunting:
Inilah kode yang saya coba:
// delegates: AVCapturePhotoCaptureDelegate & AVCaptureDepthDataOutputDelegate
@IBOutlet var image_view: UIImageView!
@IBOutlet var capture_button: UIButton!
var captureSession: AVCaptureSession?
var sessionOutput: AVCapturePhotoOutput?
var depthOutput: AVCaptureDepthDataOutput?
var previewLayer: AVCaptureVideoPreviewLayer?
@IBAction func capture(_ sender: Any) {
self.sessionOutput?.capturePhoto(with: AVCapturePhotoSettings(format: [AVVideoCodecKey: AVVideoCodecType.jpeg]), delegate: self)
}
func photoOutput(_ output: AVCapturePhotoOutput, didFinishProcessingPhoto photo: AVCapturePhoto, error: Error?) {
self.previewLayer?.removeFromSuperlayer()
self.image_view.image = UIImage(data: photo.fileDataRepresentation()!)
let depth_map = photo.depthData?.depthDataMap
print("depth_map:", depth_map) // is nil
}
func depthDataOutput(_ output: AVCaptureDepthDataOutput, didOutput depthData: AVDepthData, timestamp: CMTime, connection: AVCaptureConnection) {
print("depth data") // never called
}
override func viewDidLoad() {
super.viewDidLoad()
self.captureSession = AVCaptureSession()
self.captureSession?.sessionPreset = .photo
self.sessionOutput = AVCapturePhotoOutput()
self.depthOutput = AVCaptureDepthDataOutput()
self.depthOutput?.setDelegate(self, callbackQueue: DispatchQueue(label: "depth queue"))
do {
let device = AVCaptureDevice.default(for: .video)
let input = try AVCaptureDeviceInput(device: device!)
if(self.captureSession?.canAddInput(input))!{
self.captureSession?.addInput(input)
if(self.captureSession?.canAddOutput(self.sessionOutput!))!{
self.captureSession?.addOutput(self.sessionOutput!)
if(self.captureSession?.canAddOutput(self.depthOutput!))!{
self.captureSession?.addOutput(self.depthOutput!)
self.previewLayer = AVCaptureVideoPreviewLayer(session: self.captureSession!)
self.previewLayer?.frame = self.image_view.bounds
self.previewLayer?.videoGravity = AVLayerVideoGravity.resizeAspectFill
self.previewLayer?.connection?.videoOrientation = AVCaptureVideoOrientation.portrait
self.image_view.layer.addSublayer(self.previewLayer!)
}
}
}
} catch {}
self.captureSession?.startRunning()
}
Saya mencoba dua hal, satu di mana data kedalamannya nihil dan satu lagi di mana saya mencoba memanggil metode delegasi kedalaman.
Apakah ada yang tahu apa yang saya lewatkan?
