闲话不多说，具体在windows下下载PCL与解压pcl可以看https://www.yuque.com/huangzhongqing/pcl/这位大佬的文章，那我就具体说一下踩过点坑：
踩坑点1：
按照大佬的文章的步骤进行解压与下载，我的PCL环境下在了K盘中，但是最后不知怎么的我的openni2文件夹下在了C盘里，也就是说3rdparty文件夹下的openni2没有下一层目录了，我的做法就是把c盘里openni2目录下的文件都复制到了K盘中。当然也可以不复制，在配置环境变量时记得要写c盘的openni2不要写K盘的就可以。
踩坑点2：
安装PCL时，如果选择添加环境变量可能会出现“环境变量长度超过1023”这样类似的错误，这时候需要手动配置一下，下面是我的配置办法：
在这张图中，这三个变量应该是安装的时候可以自动写到环境变量里的，第三行是我手动修改了，放到了k盘里，其实可以不放，只要记得是C盘就行，前两行也同样。还有就是下图这个
也是可以自动填写上的，需要我们手动添加的是下面这些：
我们在Path里，尾部加上这些就可以了。
踩坑点3：
链接库问题，这也是比较棘手的问题之一，在3rdparty下的每一个文件夹下的lib文件夹中，新建一个txt文件，内容填写：DIR *.lib /B >liblist.txt DIR .lib /B：列出当前目录中所有以 .lib 为扩展名的文件，且使用简洁的输出格式。DIR：显示目录中的文件和子目录列表。*.lib：匹配所有以 .lib 结尾的文件。/B：使用简洁格式输出，只显示文件名，不显示日期、时间、文件大小等详细信息。liblist.txt是你需要重定向的文件名。最后再把写入命令的txt后缀修改为bat，双击执行即可吧lib文件名称全部写入到liblist.txt中。完成上述操作后，当我们执行时，可能会出现下图的错误：
这个错误的排除也是耗费了我很长时间，最后找到了原因：上面我们得到的liblist列表中，同时包括debug和release版本的lib，那么vs执行的时候就会产生冲突，从而报错，具体做法是我们可以去掉非debug版本的lib文件，比如你把“pcl_registrationd.lib”和 “pcl_registration.lib” 都写上去了那么就去掉后面不带d的，前面有“gd”后缀的一样，保留它，去掉不带gd的。下面是1.14.1我整理好的库：

上面这个问题，同样适用于执行结果不报错，但是却在console窗口显示非0退出的语句这个问题。
踩坑点4：
无法解析的外部符号 "void __cdecl vtkRenderingOpenGL_AutoInit_Construct(void)" (?vtkRenderingOpenGL_AutoInit_Construct@@YAXXZ)，函数 "public: __cdecl `anonymous namespace'::vtkRenderingOpenGL_ModuleInit::vtkRenderingOpenGL_ModuleInit(void)" (??0vtkRenderingOpenGL_ModuleInit@?A0xdbae2661@@QEAA@XZ)
我用的是文章开头大佬的文章中的代码：
#include <pcl/visualization/cloud_viewer.h>
#include <iostream>
#include <pcl/io/io.h>
#include <pcl/io/pcd_io.h>
#include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkInteractionStyle);
VTK_MODULE_INIT(vtkRenderingFreeType);
VTK_MODULE_INIT(vtkRenderingOpenGL);int user_data;void viewerOneOff(pcl::visualization::PCLVisualizer& viewer)
{viewer.setBackgroundColor(1.0, 0.5, 1.0);pcl::PointXYZ o;o.x = 1.0;o.y = 0;o.z = 0;viewer.addSphere(o, 0.25, "sphere", 0);std::cout << "i only run once" << std::endl;}void viewerPsycho(pcl::visualization::PCLVisualizer& viewer)
{static unsigned count = 0;std::stringstream ss;ss << "Once per viewer loop: " << count++;viewer.removeShape("text", 0);viewer.addText(ss.str(), 200, 300, "text", 0);//FIXME: possible race condition here:user_data++;
}int main()
{pcl::PointCloud<pcl::PointXYZRGBA>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZRGBA>);pcl::io::loadPCDFile("rabbit.pcd", *cloud);pcl::visualization::CloudViewer viewer("Cloud Viewer");//blocks until the cloud is actually renderedviewer.showCloud(cloud);//use the following functions to get access to the underlying more advanced/powerful//PCLVisualizer//This will only get called onceviewer.runOnVisualizationThreadOnce(viewerOneOff);//This will get called once per visualization iterationviewer.runOnVisualizationThread(viewerPsycho);while (!viewer.wasStopped()){//you can also do cool processing here//FIXME: Note that this is running in a separate thread from viewerPsycho//and you should guard against race conditions yourself...user_data++;}return 0;
}
只需要把VTK_MODULE_INIT(vtkRenderingOpenGL);改为VTK_MODULE_INIT(vtkRenderingOpenGL2);即可
