C++ Sample Infrared Stream Viewer

Update on 2025-07-25 06:59:08

Function description: Demonstrate obtaining infrared camera images, displaying infrared images, and exiting the program with the ESC_KEY key

| This example is based on the C++High Level API for demonstration

Create a pipeline and configure stream information

// Create a pipeline with default device
ob::Pipeline pipe;

// Get all stream profiles of the infrared camera, including stream resolution, frame rate, and frame format
// Please adjust the sensor according to the actual product, some device types only have OB_SENSOR_IR_LEFT and OB_SENSOR_IR_RIGHT.
auto profiles = pipe.getStreamProfileList(OB_SENSOR_IR);

if(profiles == nullptr) {
    std::cerr
        << "The obtained IR resolution list is NULL. For binocular structured light devices, try using the doubleIr example to turn on the ir data stream. "
        << std::endl;
    return 0;
}

std::shared_ptr<ob::VideoStreamProfile> irProfile = nullptr;
try {
    // Find the corresponding profile according to the specified format, first look for the y16 format
    irProfile = profiles->getVideoStreamProfile(640, 480, OB_FORMAT_Y8, 30);
}
catch(ob::Error &e) {
    // If the specified format is not found, search for the default profile to open the stream
    irProfile = std::const_pointer_cast<ob::StreamProfile>(profiles->getProfile(OB_PROFILE_DEFAULT))->as<ob::VideoStreamProfile>();
}

// By creating config to configure which streams to enable or disable for the pipeline, here the infrared stream will be enabled
std::shared_ptr<ob::Config> config = std::make_shared<ob::Config>();
config->enableStream(irProfile);

Enable pipeline

pipe.start(config);

Get frame data

auto frameSet = pipe.waitForFrames(100);

Stop pipeline

pipe.stop();
