yolov8 Windows+CPU 实现目标检测和绘制结果图

YOLOv8 由 Ultralytics 提供,并支持全方位的视觉 AI 任务,包括检测、分割、姿态估计、跟踪和分类。这种多功能性使用户能够在各种应用和领域中利用 YOLOv8 的功能。

1. Windows 环境下使用 CPU 运行 yolov8 环境搭建

(1)使用 Anaconda 搭建 yolov8 虚拟环境:conda create -n yolov8 python==3.9

(2)进入该虚拟环境:conda activate yolov8

(3)安装 yolov8:pip install ultralytics

安装完成如下所示:

 2. 使用 yolov8 官方下载的预训练模型进行目标检测

(1)下载 yolov8 官方自带的目标检测预训练模型 ,这里我使用的是 yolov8n.pt

(2)代码实现:

 1 # 导入所需的库函数
 2 from ultralytics import YOLO
 3 from PIL import Image
 4 import os
 5 
 6 # Load your model 导入模型
 7 model = YOLO('./model/yolov8n.pt')  # For example, 'yolov8n.pt'
 8 # 定义图片读取文件
 9 path_input = "./image"
10 # 定义检测结果保存文件
11 path_output = "./output"
12 
13 # 使用模型进行目标检测
14 for file_name in os.listdir(path_input):
15     # 得到图片路径
16     path_image = os.path.join(path_input, file_name)
17     # Run prediction 预测
18     results = model(path_image)
19     # After running the input through the model, it returns an array of results for each input image.
20     # As we provided only a single image, it returns an array with a single item that you can extract like this:
21     result = results[0]
22     # Now, iterate over detected objects
23     for det in result.boxes:
24         # det is now a single detection with attributes you can directly access
25         xmin, ymin, xmax, ymax = det.xyxy[0]  # Coordinates
26         conf = det.conf  # Confidence
27         cls = det.cls  # Class ID
28         class_name = result.names[cls[0].item()]   # class name
29         print(f"Box coordinates: {xmin}, {ymin}, {xmax}, {ymax}, Confidence: {conf}, Class Name: {class_name}")
30     # 显示图片并保存(这里如果使用matplotlib显示不出图片)
31     image = Image.fromarray(result.plot()[:, :, ::-1])
32     image.show()
33     image.save(os.path.join(path_output, file_name))

 代码运行结果:
