Question

这是应用中使用的代码，

    //setup recognizer
let usdlRecognizer = MBUsdlCombinedRecognizer()
usdlRecognizer.returnFullDocumentImage = true
usdlRecognizer.scanUncertain = false

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

        if state == MBRecognizerResultState.valid {
            // first, pause scanning until we process all the results
            documentVerificationOverlayViewController.recognizerRunnerViewController?.pauseScanning()

            DispatchQueue.main.async(execute: {() -> Void in
                documentVerificationOverlayViewController.dismiss(animated: false, completion: {

                })

                self.parseResult(recognizer: self.recognizer)
                if let recognizer = self.recognizer as? MBUsdlCombinedRecognizer, recognizer.result.documentDataMatch == true {
                 // *********** Its always coming here even with mismatched cards ****************
                   print("both sides of cards matched.. success")
                } else {
                        showAlert(title: "Error", message: "Data not matched", vc: self, okAction: {

                        })
                }
            })
        }
    }

即使我们使用其他人的美国驾驶执照进行扫描，也总是会成功进入if语句。

Answer 1

这是因为MBUSDLCombinedRecognizer仅扫描正面的人脸和文档图像。它不会读取字段，所有其他字段都是从背面的pdf417条形码读取的，因此它无法比较正面和背面的结果。我们正在努力为USDL的前端提供支持，在2019年第二季度，我们将获得一些令人振奋的消息！一个小提示：Autodetection

亲切的问候

MicroBlink SDK的USDL组合识别器documentDataMatch返回始终为true
