前言

接到一个项目,需要用c++和单片机通信,还要使用yolo模型来做到目标检测的任务,但目前网上的各种博客并没有完整的流程教程,让我在部署过程费了不少劲,也踩了不少坑(甚至一度把ubuntu干黑屏)。于是想把训练及部署过程记录下来,并留给后来者方便使用。(博主使用的系统是ubuntu20.04)

1.Yolo简介

作为一个经典且实用的目标检测模型,yolo的性能强大已无需多言,现在(2023.4.1)yolo模型已经推出到yolov8,但是推理速度上yolov5还是够快且够用,而且对各种外部硬件的适配性强,如oak相机支持的模型还在yolov5-yolov6,所以博主这里选择yolov5进行训练。

2.onnxruntime简介

onnxruntime是微软推出的一款推理框架,我们可以很方便的利用它运行一个onnx模型,而且它支持多种运行后端,包括CPU,GPU,TensorRT,DML等。onnxruntime可以说是对onnx模型最原生的支持了,而且onnxruntime也有在C++上部署使用的相关库,所以我们选择onnxruntime作为我们的推理框架进行部署。

3.Yolov5模型训练及转换

怎么训练呢?

对于yolov5模型的训练,其实选择哪个都可以,博主这里模型使用的是https://github.com/ultralytics/yolov5/tree/v5.0

使用c++onnxruntime部署yolov5模型并使用CUDA加速(超详细)

可以看到这个图片中有三个output,这样的结果是不能用的,我们需要的output是类似于[1,25200,7]这样的结果,并且这个结果必须在第一位上,通过观察可以知道25200是上图中三个输出结果中三个先验框大小和数量相乘得到的而我们训练使用的yolov5模型export的转换结果却不是这样的总和。

那怎么转换呢?

很简单,通过观察yolov5中yolo部分的代码发现

这个代码中的return是有问题的,返回结果不是我们想要的存在类似与[1,25200,7]的结果,而是详细细分的。这里我们最好不要改动yolo部分的代码,这可能会牵连其他部分从而产生错误。我们直接使用https://github.com/ultralytics/yolov5 这个模型来进行转换

python export.py --weights yolov5s.pt --include torchscript onnx openvino engine coreml tflite ...

注意yolov5s.pt处填自己训练结果的pt文件地址。然后我们使用netron查看得到的onnx模型

4.利用cmake向C++部署该onnx模型

1.下载onnxruntime-gpu版本

2.下载vscode并创建cmake工程

3.别忘了NVIDIA驱动以及CUDA和CUDNN的安装!

1.NVIDIA驱动

使用c++onnxruntime部署yolov5模型并使用CUDA加速(超详细)

2.cuda和cudnn的安装

3.cmake
