UBUNTU20.04配置pcl开发环境

好的，针对您的问题，我可以给您提供以下步骤：

1. 安装依赖库

sudo apt-get update
sudo apt-get install git build-essential linux-libc-dev
sudo apt-get install cmake cmake-gui
sudo apt-get install libusb-1.0-0-dev libusb-dev libudev-dev
sudo apt-get install mpi-default-dev openmpi-bin openmpi-common  
sudo apt-get install libflann1.8 libflann-dev
sudo apt-get install libeigen3-dev
sudo apt-get install libboost-all-dev
sudo apt-get install libvtk6-dev libvtk6.3-qt 
sudo apt-get install libvtk7-dev libvtk7-qt-dev

2. 下载PCL源码

git clone https://github.com/PointCloudLibrary/pcl.git

3. 编译安装PCL

cd pcl
mkdir release
cd release
cmake -DCMAKE_BUILD_TYPE=None -DCMAKE_INSTALL_PREFIX=/usr \
    -DBUILD_GPU=ON -DBUILD_apps=ON -DBUILD_examples=ON \
    -DCMAKE_INSTALL_PREFIX=/usr ..
make -j8
sudo make install

4. 配置环境变量

echo "export PCL_ROOT=/usr/share/pcl-1.8" >> ~/.bashrc
echo "export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH" >> ~/.bashrc
source ~/.bashrc

5. 测试PCL是否安装成功

pcl_viewer

如果能够打开PCL Viewer，则说明PCL已经成功安装。
