整合 YOLOv5 和 PyQt5 可以实现一个图像识别软件,以下是一些简单的步骤:
1. 安装 YOLOv5 和 PyQt5:在命令行中运行以下命令:
```
pip install yolov5
pip install PyQt5
```
2. 创建 GUI:使用 PyQt5 创建一个 GUI 界面,可以包含一个按钮和一个显示图像的标签。
3. 加载 YOLOv5 模型:在按钮的点击事件中加载预训练的 YOLOv5 模型,并使用其识别图片上的物体。
4. 显示识别结果:将识别结果绘制在图片上,并在标签中显示。
以下是一个简单的代码示例:
```python
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton, QLabel, QFileDialog
from PyQt5.QtGui import QPixmap
import sys
import cv2
import torch
import numpy as np
from yolov5.models.experimental import attempt_load
from yolov5.utils.torch_utils import select_device
class MainWindow(QMainWindow):
def __init__(self):
super().__init__()
self.title = 'YOLOv5 Object Detection'
self.left = 100
self.top = 100
self.width = 640
self.height = 480
self.initUI()
def initUI(self):
self.setWindowTitle(self.title)
self.setGeometry(self.left, self.top, self.width, self.height)
# create a label to display the image
self.image_label = QLabel(self)
self.image_label.setGeometry(10, 10, 620, 400)
# create a button to select an image
self.button = QPushButton('Select Image', self)
self.button.setGeometry(10, 420, 100, 30)
self.button.clicked.connect(self.select_image)
# create a button to perform object detection
self.detect_button = QPushButton('Detect Objects', self)
self.detect_button.setGeometry(120, 420, 100, 30)
self.detect_button.clicked.connect(self.detect_objects)
self.show()
def select_image(self):
# open a file dialog to select an image
file_dialog = QFileDialog()
file_dialog.setFileMode(QFileDialog.ExistingFile)
file_dialog.setNameFilter('Images (*.png *.xpm *.jpg *.bmp)')
if file_dialog.exec_():
filename = file_dialog.selectedFiles()[0]
pixmap = QPixmap(filename)
self.image_label.setPixmap(pixmap)
def detect_objects(self):
# load the YOLOv5 model
device = select_device('')
model = attempt_load('yolov5s.pt', map_location=device)
# read the image from the label
pixmap = self.image_label.pixmap()
img = cv2.imread(pixmap.toImage().bits().asstring())
# perform object detection
results = model(img)
# draw bounding boxes on the image
for result in results.xyxy:
x1, y1, x2, y2, class_id, prob = result
cv2.rectangle(img, (int(x1), int(y1)), (int(x2), int(y2)), (0, 255, 0), 2)
cv2.putText(img, f'{model.names[int(class_id)]} {prob:.2f}', (int(x1), int(y1)-10),
cv2.FONT_HERSHEY_SIMPLEX, 0.5, (0, 255, 0), 2)
# convert the image to a QPixmap and display it
img = cv2.cvtColor(img, cv2.COLOR_BGR2RGB)
h, w, c = img.shape
pixmap = QPixmap.fromImage(QImage(img.data, w, h, w*c, QImage.Format_RGB888))
self.image_label.setPixmap(pixmap)
if __name__ == '__main__':
app = QApplication(sys.argv)
window = MainWindow()
sys.exit(app.exec_())
```
在此示例中,我们创建了一个 `MainWindow` 类,它继承自 `QMainWindow` 类,并包含一个显示图像的标签和两个按钮。当用户点击“Select Image”按钮时,将打开文件对话框以选择要处理的图像。当用户点击“Detect Objects”按钮时,将加载 YOLOv5 模型并使用其检测图像上的物体。最后,我们将识别结果绘制在图像上,并在标签中显示。
