MicroBlink SDK 的 USDL 组合识别器文档 DataMatch 返回始终为 true

Question

在此处使用的代码，

    //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: {
                        })
                }
            })
        }
    }

即使我们使用不同人的美国驾驶执照扫描，它也将始终取得成功的范围。

那是因为mbusdlcombinedRognizer仅在正面扫描面部和文档图像。它没有读取字段，所有其他字段均在背面的PDF417条形码中读取，因此无法比较前面和背面的结果。我们正在为USDL的前侧提供支持，在2019年第2季度，我们将有一些令人兴奋的消息！一个小提示：自动检测
