Good morning,

We are doing joint tests with different OCR systems and we need to process the same frames. So, I was wondering how it could pass directly to the Real Time Recognition path where to extract the frames to be processed.

Hello!

RTR enables your application to capture information directly from the preview frames of your smartphone camera, without actually snapping a picture. Briefly, you need to implement the Callback interface which will be used to pass the data to and from the recognition service. Here are the recommendations on what the interface's methods should do:

onRequestLatestFrame method should retrieve the image from the camera and pass it on to the IDataCaptureService.submitRequestedFrame method.

onFrameProcessed method is where you work with the results.

Full scenario on how to capture information directly from the frames please find in the Help → Guided Tour → How to Capture Text from Camera
