一 、必须先安装VTK,首先准备编译环境,再下载VTK源码编译安装
(1)安装Qt5
从Qt官网下载开源版本,官网地址:https://www.qt.io/download-open-source/#section-2
在官网里点击go open source,填写邮箱等信息,就可以获得下载地址了,目前我下载的版本名称是qt-unified-linux-x64-3.1.0-online.run。下载完成后,应该是不能直接双击运行的,要在终端键入如下命令来运行:
sudo chmod u+x qt-unified-linux-x64-3.1.0-online.run
sudo ./qt-unified-linux-x64-3.1.0-online.run
根据提示进行,并设置安装路径就好(我用的是默认的路径)
(2)安装X11
sudo apt-get install libx11-dev libxext-dev libxtst-dev libxrender-dev libxmu-dev libxmuu-dev
(3)安装OpenGL
sudo apt-get install build-essential libgl1-mesa-dev libglu1-mesa-dev
(4)安装libglut-dev
sudo apt-get install freeglut3-dev
(5)在VTK官网下载,https://www.vtk.org/download/ ,我下载的是VTK-8.2.0.tar.gz,
下载完成后,提取到Home目录下。然后终端一步一步进行如下操作:
cd VTK-8.2.0
mkdir release
cd release
cmake ..
sudo make
sudo make install
编译时间较长,完成后,继续下面等pcl编译安装。
二、首先,要先安装一大堆依赖库,这个过程耗时挺久的,终端操作如下一步一步进行:
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 libvtk5.10-qt4 libvtk5.10 libvtk5-dev
sudo apt-get install libqhull* libgtest-dev
sudo apt-get install freeglut3-dev pkg-config
sudo apt-get install libxmu-dev libxi-dev
sudo apt-get install mono-complete
sudo apt-get install qt-sdk openjdk-8-jdk openjdk-8-jre
接着从github上把PCL源码clone下来
git clone https://github.com/PointCloudLibrary/pcl.git
pcl源码下载后应该出现在home下,有一个pcl文件,然后:
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
sudo make install
至此,pcl安装结束。
三、测试pcl是否安装成功
在home下进入pcl文件夹,新建文件夹pcl_test,进入pcl_test文件夹,新建文档并命名为pcl_test.cpp,继续新建文档并命名为CMakeLists.txt,其中,pcl_test.cpp文档内的代码如下:
#include
#include
#include
#include
#include
#include
int main(int argc, char **argv) {
std::cout << "Test PCL !!!" << std::endl;
pcl::PointCloud::Ptr point_cloud_ptr (new pcl::PointCloud);
uint8_t r(255), g(15), b(15);
for (float z(-1.0); z <= 1.0; z += 0.05)
{
for (float angle(0.0); angle <= 360.0; angle += 5.0)
{
pcl::PointXYZRGB point;
point.x = 0.5 * cosf (pcl::deg2rad(angle));
point.y = sinf (pcl::deg2rad(angle));
point.z = z;
uint32_t rgb = (static_cast(r) << 16 |
static_cast(g) << 8 | static_cast(b));
point.rgb = *reinterpret_cast(&rgb);
point_cloud_ptr->points.push_back (point);
}
if (z < 0.0)
{
r -= 12;
g += 12;
}
else
{
g -= 12;
b += 12;
}
}
point_cloud_ptr->width = (int) point_cloud_ptr->points.size ();
point_cloud_ptr->height = 1;
pcl::visualization::CloudViewer viewer ("test");
viewer.showCloud(point_cloud_ptr);
while (!viewer.wasStopped()){ };
return 0;
}
CMakeLists.txt文档内的代码如下:
cmake_minimum_required(VERSION 2.6)
project(pcl_test)
find_package(PCL 1.2 REQUIRED)
include_directories(${PCL_INCLUDE_DIRS})
link_directories(${PCL_LIBRARY_DIRS})
add_definitions(${PCL_DEFINITIONS})
add_executable(pcl_test pcl_test.cpp)
target_link_libraries (pcl_test ${PCL_LIBRARIES})
install(TARGETS pcl_test RUNTIME DESTINATION bin)
然后打开终端,进行如下操作:
cd pcl/pcl_test
mkdir build
cd build
cmake ..
make
make成功后,终端继续键入:
./pcl_test
