# 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和config

// Create a pipeline to open the Infrared stream after connecting the device
pipeline = ob_create_pipeline(&error);
check_error(error);

// Create config to configure the resolution, frame rate, and format of the Infrared stream
ob_config *config = ob_create_config(&error);
check_error(error);

获取左IR流配置

// Configure the infrared stream(IR_LEFT)
ob_stream_profile      *ir_left_profile  = NULL;
ob_stream_profile_list *ir_left_profiles = ob_pipeline_get_stream_profile_list(pipeline, OB_SENSOR_IR_LEFT, &error);
check_error(error);

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

// Find the corresponding profile according to the specified format, first look for the y16 format
ir_left_profile = ob_stream_profile_list_get_profile(ir_left_profiles, OB_PROFILE_DEFAULT, &error);
check_error(error);

// enable stream
ob_config_enable_stream(config, ir_left_profile, &error);
check_error(error);

获取右IR流配置

// Configure the infrared stream(IR_RIGHT)
ob_stream_profile      *ir_right_profile  = NULL;
ob_stream_profile_list *ir_right_profiles = ob_pipeline_get_stream_profile_list(pipeline, OB_SENSOR_IR_RIGHT, &error);
check_error(error);

// Find the corresponding profile according to the specified format, first look for the y16 format
ir_right_profile = ob_stream_profile_list_get_profile(ir_right_profiles, OB_PROFILE_DEFAULT, &error);
check_error(error);

// enable stream
ob_config_enable_stream(config, ir_right_profile, &error);
check_error(error);

通过config开启pipeline

ob_pipeline_start_with_config(pipeline, config, &error);
check_error(error)

获取左右IR帧数据

ob_frame *ir_left_frame = ob_frameset_get_frame(frameset, OB_FRAME_IR_LEFT, &error);
check_error(error);

ob_frame *ir_right_frame = ob_frameset_get_frame(frameset, OB_FRAME_IR_RIGHT, &error);
check_error(error);

// 停止 pipeline

ob_pipeline_stop(pipeline, &error);
check_error(error);

释放相关资源

// destroy the window
delete win;

// destroy profile
ob_delete_stream_profile(ir_left_profile, &error);
check_error(error);

// destroy profile list
ob_delete_stream_profile_list(ir_left_profiles, &error);
check_error(error);

// destroy profile
ob_delete_stream_profile(ir_right_profile, &error);
check_error(error);

// destroy profile list
ob_delete_stream_profile_list(ir_right_profiles, &error);
check_error(error);

// destroy the pipeline
ob_delete_pipeline(pipeline, &error);
check_error(error);
