目前網上大部分PCL安裝教程針對的是1.8版本. 按照網上的教程安裝PCL 1.9后缺少很多東西. 編譯PCL demo時典型報錯為:?fatal error: pcl/visualization/pcl_visualizer.h: No such file or directory. 然后發現在PCL安裝目錄下("/usr/include/pcl-1.9/")根本沒有visualization文件夾. 博主出現這種問題的原因主要是cmake版本太低. 解決過程如下:

1. 安裝高版本cmake

1) 首先卸載舊版本cmake

apt-get autoremove cmake

2) 下載高版本cmake, 以13.4為例

wget https://cmake.org/files/v3.13/cmake-3.13.4-Linux-x86_64.tar.gz

3) 解壓并進入cmake-3.13.4-Linux-x86_64目錄

tar -zxvf cmake-3.13.4-Linux-x86_64.tar.gz

cd cmake-3.13.4-Linux-x86_64/

4) 配置并安裝

./configure

make

sudo make install

5) 解決路徑問題

export PATH=/usr/local/bin:$PATH

export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH

cmake

6) 驗證

cmake --version

2. 自己編譯安裝PCL 1.9

1) 安裝依賴項

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

2) 下載并解壓pcl

3) 編譯安裝

解壓完成后進入pcl目錄

cd pcl

mkdir build

cd build

cmake -DCMAKE_BUILD_TYPE=None -DCMAKE_INSTALL_PREFIX=/usr?-DBUILD_GPU=ON -DBUILD_apps=ON -DBUILD_examples=ON?-DCMAKE_INSTALL_PREFIX=/usr ..

make

如果make時報錯: make[2]: *** No rule to make target '/usr/lib/x86_64-linux-gnu/libproj.so', needed by 'lib/libpcl_io.so.1.9.1.99'。 停止。CMakeFiles/Makefile2:499: recipe for target 'io/CMakeFiles/pcl_io.dir/all' failed

建立軟連接, 終端中輸入:?sudo ln -s /usr/lib/x86_64-linux-gnu/libproj.so.9 /usr/lib/x86_64-linux-gnu/libproj.so

之后重新make

make成功后, 在終端輸入:?sudo make install

完成安裝.

3. PCL測試程序

#include

int main(int argc, char **argv)

{

std::cout << "Test PCL !!!" << std::endl;

pcl::PointCloud<:pointxyzrgb>::Ptr point_cloud_ptr (new pcl::PointCloud<:pointxyzrgb>);

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------------------

# cmake needs this line

# Define project name

find_package(PCL 1.9 REQUIRED)
