Get Original Binocular Image

Use Start() or Stop() , to start or stop data capturing. If you only need the image data, use Source::VIDEO_STREAMING .

When data capturing starts, call WaitForStreams() function. Once data capturing begins, use GetStreamData() to get your data.

Reference commands:

auto &&api = API::Create(argc, argv);

api->Start(Source::VIDEO_STREAMING);

cv::namedWindow("frame");

while (true) {
  api->WaitForStreams();

  auto &&left_data = api->GetStreamData(Stream::LEFT);
  auto &&right_data = api->GetStreamData(Stream::RIGHT);

  cv::Mat img;
  cv::hconcat(left_data.frame, right_data.frame, img);
  cv::imshow("frame", img);

  char key = static_cast<char>(cv::waitKey(1));
  if (key == 27 || key == 'q' || key == 'Q') {  // ESC/Q
    break;
  }
}

api->Stop(Source::VIDEO_STREAMING);

The above code uses OpenCV to display the image. When the display window is selected, pressing ESC/Q will end the program.
