简介

OpenPose人体姿态识别项目是美国卡耐基梅隆大学(CMU)基于卷积神经网络和监督学习并以caffe为框架开发的开源库。可以实现人体动作、面部表情、手指运动等姿态估计。适用于单人和多人,具有极好的鲁棒性,是世界上首个基于深度学习的实时多人二维姿态估计应用。人体姿态估计技术在体育健身、动作采集、人机交互、舆情监测等领域具有广阔的应用前景。

算法体验

如果仅仅是想体验下这个项目,官方提供了windows版的可执行文件下载,有gpucpu2个版本,地址是: https://github.com/CMU-Perceptual-Computing-Lab/openpose/releases/,解压后进入文件夹,下载项目中需要用到的各种模型

cd openpose\models
.\getModels.bat

openpose

使用本地视频文件进行测试

cd ..
bin\OpenPoseDemo.exe --video examples\media\video.avi

openpose

源码编译

我这里是有gpu环境,因此需要安装nvidia的驱动,cudacuDNN,具体安装方法前面的博文已经介绍过了,参考下面链接

git clone https://github.com/CMU-Perceptual-Computing-Lab/openpose.git
cd openpose
conda create -n openpose python=3.7
conda activate openpose
sudo apt install cmake build-essential
mkdir build
cd build
cmake ..
make -j `nproc`
cd ../models
./getModels.sh
cd ..
./build/example/openpose.bin --video examples/media/video.avi

openpose

如果原来的系统中已经安装过了caffe,那么openpose可以直接使用而不需要再次安装了

cmake -DBUILD_CAFFE=OFF -DCaffe_INCLUDE_DIRS=$somewhere/caffe/include/ -DCaffe_LIBS=$somewhere/lib/libcaffe.so ..

如果需要在python中使用的话,cmake时需要加上参数-DBUILD_PYTHON=ON

如果不喜欢用命令行去配置cmake,可以使用cmake-gui

sudo apt install cmake-qt-gui

openpose

模型下载

使用官方的模型下载脚本,速度非常的慢,这里将工程中用到的模型整理了,放在了百度网里,方便大家下载

这是系统中缺失了pthread相关的库,解决方法

sudo apt-get install manpages-posix manpages-posix-dev

caffe代码拉不下来

CMU自己维护了一个caffe的工程,但是找了一圈,并没有发现有c95002f这个tag,所以,在配置的时候拉不下来源码,其实clone最新的就可以了,因此去修改CMakeLists.txt,将c95002f替换成master就可以了

openpose

protobuf版本不一致

Protobuf compiler version doesn't match library version 3.8.0

我这里使用的是anaconda的环境,默认安装的版本是3.11.4,与caffe要求的3.8.0不相符,使用conda安装3.8.0即可

conda install protobuf==3.8.0

或者也可以编译protobuf源码,步骤如下

wget https://github.com/protocolbuffers/protobuf/archive/v3.8.0.tar.gz
tar xvf protobuf-3.8.0.tar.gz
cd protobuf-3.8.0
./autogen.sh
./configure
make
sudo make install

安装完毕之后,使用protoc --version来检查下版本是不是正确

atlas报错

CMake Error at /usr/share/cmake-3.10/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
  Could NOT find Atlas (missing: Atlas_CLAPACK_INCLUDE_DIR
  Atlas_CBLAS_LIBRARY Atlas_BLAS_LIBRARY)

  cmake/Modules/FindAtlas.cmake:43 (find_package_handle_standard_args)
  cmake/Dependencies.cmake:113 (find_package)
  CMakeLists.txt:46 (include)

因为系统中并没有安装atlas,使用apt安装

sudo apt install libatlas-base-dev

make: *** [all] Error 2

这个问题是由于系统中的cmake版本引起的,openposecmake版本的最低要求是3.12,具体可以参考链接 https://github.com/CMU-Perceptual-Computing-Lab/openpose/blob/master/doc/prerequisites.md#ubuntu-prerequisites, 而ubuntu 18.04的默认版本是3.10.2。解决方法有2种,分别是

  • 使用snap安装

    安装方法非常简单,但是国内的速度是真的真的真的慢,以至于后来,实在是等不下去了,我直接拉源码编译了。愿意等的话,也是可以成功的

    sudo apt remove --purge cmake
    sudo snap install cmake --classic
    
  • 编译cmake的源码

    源码编译cmake,稍微复杂一点,步骤如下

    sudo apt remove --purge cmake
    sudo apt install libssl-dev
    wget https://github.com/Kitware/CMake/releases/download/v3.18.4/cmake-3.18.4.tar.gz
    tar xvf cmake-3.18.4
    cd cmake-3.18.4
    ./bootstrap
    make
    sudo make install

解决方法是,使用系统的pangoft

cd $HOME/anaconda3/lib/
mv libpangoft2-1.0.so.0 libpangoft2-1.0.so.0.bak
ln -s /usr/lib/x86_64-linux-gnu/libpangoft2-1.0.so.0 libpangoft2-1.0.so.0
