OrbbecSDK_v2

C++ Sample: 0.basic.quick_start

Overview

Use the SDK interface to quickly obtain the camera video stream and display it in the window.

Knowledge

Pipeline is a pipeline for processing data streams, providing multi-channel stream configuration, switching, frame aggregation, and frame synchronization functions

Frameset is a combination of different types of Frames

win is used to display the frame data.

Code overview

1. Instantiate the pipeline using the default configuration file and quickly open the video stream

        // Create a pipeline.
        ob::Pipeline pipe;
   
        // Start the pipeline with default config.
        // Modify the default configuration by the configuration file: "OrbbecSDKConfig.xml"
        pipe.start();
   

2. Create a window for showing the frames, and set the size of the window

        // Create a window for showing the frames, and set the size of the window.
        ob_smpl::CVWindow win("QuickStart", 1280, 720, ob_smpl::ARRANGE_ONE_ROW);
   

3. Open the window and display the video stream. The video stream waits for a frame of data in a blocking manner. The frame is a composite frame containing the frame data of all streams enabled in the configuration, and the waiting timeout of the frame is set

        while(win.run()) {
            // Wait for frameSet from the pipeline, the default timeout is 1000ms.
            auto frameSet = pipe.waitForFrameset();
   
            // Push the frames to the window for showing.
            win.pushFramesToView(frameSet);
        }
   

4. Use pipeline to close the video stream

        // Stop the Pipeline, no frame data will be generated
        pipe.stop();
   

Run Sample

Press the Esc key in the window to exit the program.
