论文复现--关于yolov8在姿态估计方面的研究

分类：动作捕捉
github地址：https://github.com/ultralytics/ultralytics
所需环境：
Windows10，CUDA11.6，conda 4.13.0，Visual Studio 2017；

环境搭建

# 创建环境
conda create -n yolov8 python=3.8
conda activate yolov8
 
# 个人比较偏向从源码构建 不喜欢这种方式的同学请直接采用pip安装方式：pip install ultralytics
conda install git
cd D:
cd D:\WLm_Project\MotionCatch\YOLOV8
git clone https://github.com/ultralytics/ultralytics.git
cd ultralytics

# 创建Pytorch环境 torch-1.13.1+cu116-cp38-cp38-win_amd64.whl需要预下载并拷贝到当前目录 CUDA需要提前配置
pip install torch-1.13.1+cu116-cp38-cp38-win_amd64.whl
pip install torch==1.13.1+cu116 torchvision==0.14.1+cu116 torchaudio==0.13.1 --extra-index-url https://download.pytorch.org/whl/cu116 -i https://pypi.tuna.tsinghua.edu.cn/simple

# 下载并安装ultralytics依赖项
pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple

# 编译ultralytics
pip install -v -e .  -i https://pypi.tuna.tsinghua.edu.cn/simple

编译成功

读取结果在ultralytics\runs\pose中：

# python脚本
from ultralytics import YOLO
# python
# Load a model
model = YOLO('yolov8n-pose.pt')  # load an official model
model = YOLO('path/to/best.pt')  # load a custom model

# Predict with the model
results = model('https://ultralytics.com/images/bus.jpg')  # predict on an image

# 命令行
# 读取屏幕
yolo pose predict model=yolov8n-pose.pt source='screen'  

# 读取摄像头：找到ultralytics\ultralytics\cfg的default.yaml,show的值设成True,Flase的话不会实时看到画面。命令行令source=‘0’
yolo pose predict model=yolov8n-pose.pt source='0'
