扯几句：习惯了在Windows全家桶宇宙第一IDE的大树下乘凉，编辑调试，环境部署等都很方便快捷。发现公司被禁用vs大法之后，只能尝试上Ubuntu开源的世界寻找生存，故站在各位CSDN大神前辈的肩膀上尝试部署qt+opencv+pcl的程序编辑调试之路，水平有限，也是留给自己以保存的。
第一步：更换软件源，以下是用过有效的，不然使用终端安装会下载不下来。
重要：运行脚本前，更换国内软件源，/etc/apt/source.list，以下是source.list的文件内容，供参考

第二步：安装Qt。参考链接https://blog.csdn.net/jcs1992/article/details/81506880
第三步：安装opencv
方法1：从库直接安装（如果不更换下载源，因为wall会下载失败）
sudo apt-get install libopencv-dev python-opencv
方法2：编译安装（步骤较多，没有用过故不介绍）
第四步：安装pcl点云库
安装参考链接: https://blog.csdn.net/yingmai7741/article/details/86531850
方法1：从库直接安装：
sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl
sudo apt-get update
sudo apt-get install libpcl-dev
方法2： 编译安装（步骤较多，没有用过故不介绍）
第五步：测试，使用QT测试以上库是否安装成功。.pro配置文件如下，以下是本人安装的路径和版本号，需要根据各自情况自行更改。
#opencv
INCLUDEPATH +=/usr/include
/usr/include/opencv
/usr/include/opencv2
LIBS += /usr/lib/x86_64-linux-gnu/libopencv*.so
#eigen3
INCLUDEPATH += /usr/include/eigen3
#VTK
INCLUDEPATH += /usr/include/vtk-6.3
LIBS += /usr/lib/x86_64-linux-gnu/libvtk*.so
#pcl
INCLUDEPATH += /usr/include/pcl-1.8
LIBS += /usr/lib/x86_64-linux-gnu/libpcl*.so
#boost
INCLUDEPATH += /usr/include/boost
LIBS += /usr/lib/x86_64-linux-gnu/libboost*.so
注意：1.如果编译时，遇到no such file 就去找哪个文件include进去
2.Linux可以用通配符，很方便
3.在终端寻找本地的文件存储路径 如：find / -name libopencv.so
find / -name libpcl*.so
测试main函数如下：
#include “mainwindow.h”
#include
#include
#include <pcl/io/pcd_io.h>
#include <pcl/point_types.h>
#include <pcl/io/ply_io.h>
#include <pcl/visualization/cloud_viewer.h>
#include <pcl/kdtree/kdtree_flann.h>
#include <opencv2/core/core.hpp>
#include <opencv2/highgui/highgui.hpp>
#include <opencv2/opencv.hpp>
#include
using namespace std;
using namespace cv;
int main(int argc, char *argv[])
{
Mat img = imread(“tt.jpeg”);//图片放在debug文件里
line(img,Point(1,1),Point(250,250),Scalar(0,0,255),5);//画一条直线
imshow(“可爱的小猫咪”, img);
waitKey(0);
return 0;
pcl::PointCloudpcl::PointXYZ::Ptr cloud(new pcl::PointCloudpcl::PointXYZ);
if (pcl::io::loadPLYFilepcl::PointXYZ(“bunny.ply”, cloud) == -1) // load the file，需要自己的点云文件
{
PCL_ERROR(“Couldn’t read file test_pcd.pcd \n”);
system(“PAUSE”);
return (-1);
}
pcl::visualization::CloudViewer viewer(“Viewer”);
viewer.showCloud(cloud);
system(“PAUSE”);
}
谢谢CSDN。
