显示无法定位包问题时查阅 Ubuntu Packages

2. 安装PCL

sudo apt-get install libpcl-dev

3. 测试

mkdir test_pcl && cd test_pcl
mkdir build
touch test.cpp
touch CMakeLists.txt
# 写入 test.cpp 和 CMakeLists.txt
cd build
cmake ..
make
./TEST

// test.cpp
#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;
}
