PaddleDetection C++部署示例

本目录下提供infer_xxx.cc快速完成PaddleDetection模型包括PPYOLOE/PicoDet/YOLOX/YOLOv3/PPYOLO/FasterRCNN/YOLOv5/YOLOv6/YOLOv7/RTMDet/CascadeRCNN/PSSDet/RetinaNet/PPYOLOESOD/FCOS/TTFNet/TOOD/GFL在CPU/GPU以及GPU上通过TensorRT加速部署的示例。

在部署前,需确认以下两个步骤

以Linux上推理为例在本目录执行如下命令即可完成编译测试支持此模型需保证FastDeploy版本0.7.0以上(x.x.x>=0.7.0)

以ppyoloe为例进行推理部署

mkdir build
cd build
# 下载FastDeploy预编译库用户可在上文提到的`FastDeploy预编译库`中自行选择合适的版本使用
wget https://bj.bcebos.com/fastdeploy/release/cpp/fastdeploy-linux-x64-x.x.x.tgz
tar xvf fastdeploy-linux-x64-x.x.x.tgz
cmake .. -DFASTDEPLOY_INSTALL_DIR=${PWD}/fastdeploy-linux-x64-x.x.x
make -j

# 下载PPYOLOE模型文件和测试图片
wget https://bj.bcebos.com/paddlehub/fastdeploy/ppyoloe_crn_l_300e_coco.tgz
wget https://gitee.com/paddlepaddle/PaddleDetection/raw/release/2.4/demo/000000014439.jpg
tar xvf ppyoloe_crn_l_300e_coco.tgz

以上命令只适用于Linux或MacOS, Windows下SDK的使用方式请参考:

如果用户使用华为昇腾NPU部署, 请参考以下方式在部署前初始化部署环境:

PaddleDetection C++接口

模型类

PaddleDetection目前支持6种模型系列类名分别为PPYOLOE, PicoDet, PaddleYOLOX, PPYOLO, FasterRCNNSSD,PaddleYOLOv5,PaddleYOLOv6,PaddleYOLOv7,RTMDet,CascadeRCNN,PSSDet,RetinaNet,PPYOLOESOD,FCOS,TTFNet,TOOD,GFL所有类名的构造函数和预测函数在参数上完全一致本文档以PPYOLOE为例讲解API

fastdeploy::vision::detection::PPYOLOE(
        const string& model_file,
        const string& params_file,
        const string& config_file
        const RuntimeOption& runtime_option = RuntimeOption(),
        const ModelFormat& model_format = ModelFormat::PADDLE)

PaddleDetection PPYOLOE模型加载和初始化其中model_file为导出的ONNX模型格式。

参数

  • model_file(str): 模型文件路径
  • params_file(str): 参数文件路径
  • config_file(str): 配置文件路径即PaddleDetection导出的部署yaml文件
  • runtime_option(RuntimeOption): 后端推理配置默认为None即采用默认配置
  • model_format(ModelFormat): 模型格式默认为PADDLE格式

Predict函数

PPYOLOE::Predict(cv::Mat* im, DetectionResult* result)

模型预测接口,输入图像直接输出检测结果。

参数

  • im: 输入图像注意需为HWCBGR格式
  • result: 检测结果,包括检测框,各个框的置信度, DetectionResult说明参考视觉模型预测结果
