## 简介<a name="section11660541593"></a>

OHOS相机驱动框架模型对上实现相机HDI接口，对下实现相机Pipeline模型，管理相机各个硬件设备。
各层的基本概念如下：

1.  HDI实现层，对上实现OHOS相机标准南向接口。

2.  框架层，对接HDI实现层的控制、流的转发，实现数据通路的搭建、管理相机各个硬件设备等功能。

3.  适配层，屏蔽底层芯片和OS差异，支持多平台适配。

## 使用方法

### 获取CameraHost

    std::shared_ptr<Camera::CameraHost> cameraHost = Camera::CameraHost::CreateCameraHost();

### 获取配置的cameraId

    std::vector<std::string> cameraIds;
cameraHost->GetCameraIds(cameraIds); #

### 打开camera设备并获取到device

    const std::shared_ptr<Camera::ICameraDeviceCallback> callback = std::make_shared<Camera::ICameraDeviceCallback>();
    
    std::shared_ptr<Camera::CameraDevice> device;
    
    std::cout << "cameraIds.front() = " << cameraIds.front() << std::endl;
    
    Camera::CamRetCode rc = cameraHost->OpenCamera(cameraIds.front(), callback, device);


### 调用device的GetStreamOperator函数获取streamOperator

    std::make_shared<Camera::IStreamOperatorCallback>();
    std::shared_ptr<Camera::StreamOperator> streamOperator = nullptr;
    rc = device->GetStreamOperator(streamOperatorCallback, streamOperator);`
### 批量创建数据流
    std::vector<std::shared_ptr<Camera::StreamInfo>> streamInfos;
    std::shared_ptr<Camera::StreamInfo> streamInfo = std::make_shared<Camera::StreamInfo>();
    streamInfo->streamId_ = 1001;
    streamInfo->width_ = 1280;
    streamInfo->height_ = 720;
    streamInfo->format_ = 2;
    streamInfo->datasapce_ = 10;
    streamInfo->intent_ = Camera::PREVIEW;
    streamInfo->tunneledMode_ = 5;
    streamInfos.push_back(streamInfo);
    rc = streamOperator->CreateStreams(streamInfos);
### 配流起流
    rc = streamOperator->CommitStreams(Camera::NORMAL, nullptr);
