# 双红外示例-DoubleInfraredViewer

支持设备：仅支持Gemini 330系列，Gemini 2 XL，Gemini 2 VL

功能描述：演示获取双红外相机图像，显示左右红外图像，并通过ESC_KEY键退出程序

>本示例基于C++ High Level API进行演示

创建Pipeline, 获取设备

ob::Pipeline pipe

配置左IR

// Get the ir_left camera configuration list
auto irLeftProfiles = pipe.getStreamProfileList(OB_SENSOR_IR_LEFT);

if(irLeftProfiles == nullptr) {
    std::cerr
        << "The obtained IR(Left) resolution list is NULL. For monocular structured light devices, try opening the IR data stream using the IR example. "
        << std::endl;
    return 0;
}

// Open the default profile of IR_LEFT Sensor, which can be configured through the configuration file
try {
    auto irLeftProfile = irLeftProfiles->getProfile(OB_PROFILE_DEFAULT);
    config->enableStream(irLeftProfile->as<ob::VideoStreamProfile>());
}
catch(...) {
    std::cout << "IR(Left) stream not found!" << std::endl;
}

配置右IR

// Get the ir_right camera configuration list
auto irRightProfiles = pipe.getStreamProfileList(OB_SENSOR_IR_RIGHT);

// Open the default profile of IR_RIGHT Sensor, which can be configured through the configuration file
try {
    auto irRightProfile = irRightProfiles->getProfile(OB_PROFILE_DEFAULT);
    config->enableStream(irRightProfile->as<ob::VideoStreamProfile>());
}
catch(...) {
    std::cout << "IR(Right) stream not found!" << std::endl;
}

开启pipeline

pipe.start(config);

获取帧数据

auto leftFrame  = frameSet->getFrame(OB_FRAME_IR_LEFT);
auto rightFrame = frameSet->getFrame(OB_FRAME_IR_RIGHT)

停止pipeline

pipe.stop();
