Method Detail

• scanNv21

   abstract VinScanResult scanNv21(ByteArray nv21, Integer width, Integer height, Integer orientation, Rect finderRect)

  Scan nv21 image to recognize VIN.

  Parameters:

  nv21 - image in form of nv21-encoded byte array

  width - image width, pixels

  height - image height, pixels

  orientation - image orientation.

  finderRect - if non-null - perform scanning only in given area.

• getMinimumNumberOfRequiredFramesWithEqualRecognitionResult

   abstract Integer getMinimumNumberOfRequiredFramesWithEqualRecognitionResult()

  Minimum number of accumulated frames that have equal result.

• setMinimumNumberOfRequiredFramesWithEqualRecognitionResult

   abstract Unit setMinimumNumberOfRequiredFramesWithEqualRecognitionResult(Integer minimumNumberOfRequiredFramesWithEqualRecognitionResult)

  Minimum number of accumulated frames that have equal result.

• getMaximumNumberOfAccumulatedFrames

   abstract Integer getMaximumNumberOfAccumulatedFrames()

  Maximum number of accumulated frames to inspect before actual result is returned.

• setMaximumNumberOfAccumulatedFrames

   abstract Unit setMaximumNumberOfAccumulatedFrames(Integer maximumNumberOfAccumulatedFrames)

  Maximum number of accumulated frames to inspect before actual result is returned.

• getOcrResolutionLimit

   abstract Integer getOcrResolutionLimit()

  The image will be downscaled to the given value during the processing. If the quality of the scanning is not enough, try to increase the limit. This variable affects the performance of the scanning process. Higher the size limit - better the quality, but the recognition is slower.

  0 - do not rescale.

• setOcrResolutionLimit

   abstract Unit setOcrResolutionLimit(Integer ocrResolutionLimit)

  The image will be downscaled to the given value during the processing. If the quality of the scanning is not enough, try to increase the limit. This variable affects the performance of the scanning process. Higher the size limit - better the quality, but the recognition is slower.

  0 - do not rescale.
