FastDeploy 安装教程

3. FastDeploy 部署(CSharp)

FastDeploy C# SDK的接口实现，为用户需要C# API的场景提供解决方案。

3.1 FastDeploy 源码编译

CMAKE_CONFIGURATION_TYPES属性设置为Release
请不要勾选WITH_GPU和ENABLE_TRT_BACKEND

开启

ENABLE_ORT_BACKEND=ON
ENABLE_PADDLE_BACKEND=ON 
ENABLE_OPENVINO_BACKEND=ON 
ENABLE_VISION=ON 
ENABLE_TEXT=ON 
WITH_CAPI=ON 
WITH_CSHARPAPI=ON

指定CMAKE_INSTALL_PREFIX 安装路径
生成fastdeploy.sln解决方案文件选择Release版本，生成编译，点击"INSTALL"->右键点击"生成"将编译好的SDK安装到先前指定的目录步骤⑤。

3.2 创建CSharp项目

在项目引用中添加–>fastdeploy_csharp；
nuget 包添加OpenCvSharp、OpenCvSharp.Extensions等包
在debug\relese项目文件夹中添加Fastdeploy的动态链接库；

fastdeploy_init.bat install %cd% D:\workSpace\Paddle\deploy\FastDeplyCsharp\FastDeplyCsharp\bin\x64\Debug

    if (!model.Initialized())
    {
        Console.WriteLine("Failed to initialize.\n");
    }
    Mat image = Cv2.ImRead(image_path);
    fastdeploy.vision.DetectionResult res = model.Predict(image);
    //Console.WriteLine(res.ToString());
    Mat res_img = fastdeploy.vision.Visualize.VisDetection(image, res, 0.5f, 1, 0.5f);
    InferPictureBox.Image = res_img.ToBitmap();
}
// 语义分割
public void fastdeplySegInfer(string image_path)

    fastdeploy.vision.segmentation.PaddleSegModel model = new fastdeploy.vision.segmentation.PaddleSegModel(model_file, params_file, config_file, runtimeoption, ModelFormat.PADDLE);

    if (!model.Initialized())
    {
        Console.WriteLine("Failed to initialize.\n");
    }
    Mat image = Cv2.ImRead(image_path);

    fastdeploy.vision.SegmentationResult res = model.Predict(image);


    Console.WriteLine(res.ToString());
    Mat res_img = fastdeploy.vision.Visualize.VisSegmentation(image, res, 0.5f);
    InferPictureBox.Image = res_img.ToBitmap();
