QT部署YOLOV5

前言

  这篇文章主要用来记录用pyqt5搭建YOLOV5的检测平台，代码是在yoloV5官方代码上加了个qt模块，目前可以支持GPU/CPU下pt/onnx推理。

一、准备工作

1、代码下载

git clone https://github.com/ultralytics/yolov5.git

2、环境安装

根据代码中的requirements.txt进行环境搭建，前提是你已有Python环境

pip install -r requirements.txt

这里需要注意的是，pyqt5需要配置下环境，参考连接为：安装pyqt5,步骤如下：

2.1、安装PyQt5

pip install PyQt5

2.2、安装Qt Designer图形界面开发工具

pip install PyQt5-tools

安装完成后，会在当前环境目录下生成如下文件

2.3、pycharm配置

先配置Qt Designer

参数如下：
Name：Qt Designer。方便记忆。实际可以任意取值。

Program：designer.exe程序绝对路径。根据实际安装路径填写,参考路径为安装的xxxx/Lib/sit-packages/qt5_applications\Qt\bin\designer.exe(其中xxxx为虚拟环境目录下)。
Working directory: $ProjectFileDir$。固定取值。

配置PyUIC，该工具是用于将Qt Designer工具开发完成的.ui文件转化为.py文件。配置打开路径同Qt Designer。参数配置说明：
Name：PyUIC。方便记忆。实际可以任意取值。
Program：python.exe程序绝对路径。根据实际安装路径填写。
Parameters：-m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py。固定取值。
Working directory: $FileDir$。固定取值。

3、模型准备

根据readme.md文件中的地址选择对应的模型下载，如图：

本文直接以yolov5s.pt进行示范

二、界面展示

1.界面大致如下

代码如下（示例）：

class Ui_Form(QtWidgets.QWidget):
    def setupUi(self, Form):
        Form.setObjectName("Form")
        Form.resize(1130, 730)

三、效果展示

1、图片效果展示如下：

2、摄像头或视频检测

四、整体代码：

若界面太大或太小，就自己添加些代码，将界面自适应电脑，或者手动修改代码33行。
