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.
|

.. code-block:: c++
|
|
|
|
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.
