C Sample Double Infrared Viewer

Supported devices: Only supports Gemini 300 series, Gemini 2 XL, Gemini 2 VL

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

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

Create pipeline and 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);

Get Left IR Stream Configuration

// 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);

Get Right IR Stream Configuration

// 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);

Enable pipeline through config

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

Get left and right IR frame data

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);

// stop pipeline

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

Release relevant resources

// 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);
