Microblink :扫描身份证正反面

Question

我正在尝试使用mircoblink扫描国家卡的两面，根据他们的文档扫描两面你必须使用控制器的MBDocumentVerificationOverlayViewController和识别器的MBBlinkIdCombinedRecognizer。但只有我的正面扫描效果很好。我正在使用演示序列密钥，我不知道它是否与我的序列密钥相关。

下面是我的代码：

    /** Create BlinkID recognizer */
    blinkIdRecognizer = MBBlinkIdCombinedRecognizer()

    /** Create BlinkID settings */
    let settings : MBDocumentVerificationOverlaySettings = MBDocumentVerificationOverlaySettings()

    /** Crate recognizer collection */
    let recognizerCollection : MBRecognizerCollection = MBRecognizerCollection(recognizers: [blinkIdRecognizer!])

    /** Create your overlay view controller */
    let documentOverlayViewController : MBDocumentVerificationOverlayViewController = MBDocumentVerificationOverlayViewController(settings: settings, recognizerCollection: recognizerCollection, delegate: self)

    /** Create recognizer view controller with wanted overlay view controller */
    let recognizerRunneViewController : UIViewController = MBViewControllerFactory.recognizerRunnerViewController(withOverlayViewController: documentOverlayViewController)

    /** Present the recognizer runner view controller. You can use other presentation methods as well (instead of presentViewController) */
    present(recognizerRunneViewController, animated: true, completion: nil)

这是我的委托代码：

extension MyVC: MBDocumentVerificationOverlayViewControllerDelegate {

    func documentVerificationOverlayViewControllerDidFinishScanningFirstSide(_ documentVerificationOverlayViewController: MBDocumentVerificationOverlayViewController) {
        print("First Side Scanned")
    }

    func documentVerificationOverlayViewControllerDidFinishScanning(_ documentVerificationOverlayViewController: MBDocumentVerificationOverlayViewController, state: MBRecognizerResultState) {

        if (self.blinkIdRecognizer?.combinedResult.resultState == MBRecognizerResultState.valid) {
            guard let result = blinkIdRecognizer?.combinedResult else {
                return
            }

            DispatchQueue.main.async {

                if self.blinkIdRecognizer?.combinedResult.scanningFirstSideDone == true {

                } else {
                    documentVerificationOverlayViewController.dismiss(animated: true, completion: nil)
                }

            }
        }
    }

    func documentVerificationOverlayViewControllerDidTapClose(_ documentVerificationOverlayViewController: MBDocumentVerificationOverlayViewController) {
        self.dismiss(animated: true, completion: nil)
    }

}

并且扫描第一方委托从未被调用过，但我在DidFinish中看到了响应

谢谢你的帮助

Answer 1

您使用的是什么版本的SDK？

在5.2版本中，我们增加了对德语ID正面和背面的扫描。

您可以在此处下载最新版本：https://github.com/BlinkID/blinkid-ios/releases

您现在可以测试它并让我们知道它是否有效吗？

我上一次使用microblink是在一年多以前，但如果我没记错的话，documentVerificationOverlayViewControllerDidFinishScanningFirstSide只适用于受支持的身份证。

如果你正在扫描一个来自其他国家的身份证，你需要自己来实现。

例如：

func documentVerificationOverlayViewControllerDidFinishScanning(_ documentVerificationOverlayViewController: MBDocumentVerificationOverlayViewController, state: MBRecognizerResultState) {
    if step == .first {
        // Present another ViewController for the back
        showBackScanner()
    } else {
        processData()
    }
}
