如何从rs2::pipeline对象中获取设备信息？

#include <librealsense2/rs.hpp>

int main()
{
    rs2::pipeline pipeline;
    rs2::config config;
    config.enable_stream(RS2_STREAM_COLOR, 640, 480, RS2_FORMAT_BGR8, 30);

    // 启动数据流
    pipeline.start(config);

    // 获取当前活动的数据流配置文件
    rs2::pipeline_profile profile = pipeline.get_active_profile();

    // 获取与数据流相关联的传感器
    rs2::sensor sensor = profile.get_device().first<rs2::sensor>();

    // 获取传感器的信息
    std::string device_name = sensor.get_info(RS2_CAMERA_INFO_NAME);
    std::string device_manufacturer = sensor.get_info(RS2_CAMERA_INFO_MANUFACTURER);
    std::string device_serial = sensor.get_info(RS2_CAMERA_INFO_SERIAL_NUMBER);

    // 打印设备信息
    std::cout << "Device Name: " << device_name << std::endl;
    std::cout << "Device Manufacturer: " << device_manufacturer << std::endl;
    std::cout << "Device Serial Number: " << device_serial << std::endl;

    // 停止数据流
    pipeline.stop();

    return 0;
}
