问题 I installed PCL using the following commands. sudo add-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl sudo apt-get update sudo apt-get install libpcl-all When I compiled my PCL program with the following lines in CMakeLists.txt find_package(PCL 1.3 REQUIRED COMPONENTS) include_directories(${PCL_INCLUDE_DIRS}) link_directories(${PCL_LIBRARY_DIRS}) add_definitions(${PCL_DEFINITIONS}) I have errors as CMake Error at CMakeLists.txt:17 (find_package): By not providing "FindPCL.cmake" in

问题 I'm new from using the PCL (Point Cloud Library). I try to declare a point cloud in QT object class in private, like this: class pcl_sys : public QThread { Q_OBJECT public: explicit pcl_sys(); ~pcl_sys(); void stop(); bool load_pcd_file(int type); signals: public slots: protected: void run(); private: pcl::PointCloud<pcl::PointXYZ>::Ptr *cloud_test; }; Then I new the point cloud when I opened up the program: pcl_sys::pcl_sys() { cloud_test=0; cloud_test= new pcl::PointCloud<pcl::PointXYZ>:

问题 I am using PCL (Point Cloud Library) have a custom PointT that inherits from pcl::PointXYZ struct PointXYZx : public pcl::PointXYZ { }; POINT_CLOUD_REGISTER_POINT_STRUCT (PointXYZx, (float, x, x) (float, y, y) (float, z, z)) And I want to plot it using CloudViewer: pcl::PointCloud<PointXYZx>::Ptr cloud (new pcl::PointCloud<PointXYZx>()); pcl::visualization::CloudViewer viewer ("Simple Cloud Viewer"); viewer.showCloud(cloud); But it gives me error saying: main.cpp: In function ‘int main()’:

问题 I am new to Computer Vision. On Cmake, i am trying to use PCL and OpenCV with a 2D Lidar sensor. I saw this tutorial: [http://unanancyowen.com/en/pcl18/#Download1 And to configure PCL on CmakeLists.txt the following code is used: cmake_minimum_required( VERSION 2.8 ) # Create Project project( solution ) add_executable( project main.cpp ) set_property( DIRECTORY PROPERTY VS_STARTUP_PROJECT "project" ) # Find Packages find_package( PCL 1.8 REQUIRED ) if( PCL_FOUND ) # Additional Include

问题 I've been trying to get PCL (1.8) working properly on my system (Ubuntu 16.04) but I am struggling to get even the basic tutorial to work. I could not install the prebuilt binaries supplied by pointclouds.org so instead followed the answer from this post and used the native repository from Ubuntu to install v1.8. I then began to run into the same issues raised in this question. I fixed some of them myself using symlinks to correct paths broken by renaming and also installed the missing

问题 I am trying to match features between two point cloud I test by changing many parameters but it always produces wrong matches. I am calculating PFH feature descriptors of SIFT features. Thank you for your suggestions. Below is the code I used // load the both point clouds pcl::io::loadPCDFile("Tee.pcd", *cloud_1); pcl::PLYReader Reader; Reader.read("tee.ply", *cloud_2); //pcl::io::loadPCDFile("Tee.pcd", *cloud_2); // Create the filtering object pcl::PassThrough<pcl::PointXYZRGB> pass; pass

问题 I am trying to visualize normals that are contained in a pcl::PointNormal point cloud. I try to do this with following code: std::shared_ptr<pcl::visualization::PCLVisualizer> viewer; std::mutex viewerMutex; void viewerThreadFunction() { while(true) { if(viewer->wasStopped()) break; viewerMutex.lock(); viewer->spinOnce(); viewerMutex.unlock(); } } int main() { viewer = std::shared_ptr<pcl::visualization::PCLVisualizer>( new pcl::visualization::PCLVisualizer("Viewer")); viewer-

问题 So I have an issue where Eigen Alignment causes serious issues with the operating system I use, QNX. Basically the OS cannot deal with the memory that way and causes very interesting seg faults. See my other question here. Any way, for this reason I wish to disable the Eigen Alignment used in PCL before I build it. I have a couple of ideas about how i might do this. EIGEN INCLUDE FILES IN PCL So PCL has the structure for most of its modules like this (this is an example of the features module

问题 I am trying to link a C++ application with PCL library. I installed PCL and all its dependencies using VCPKG. I am using Visual Studio 2017 and cmake 3.12 for X64. When I am trying to build the solution it is giving me the following Errors. E0145 member "boost::filesystem::path::separator" may not be initialized C:\vcpkg-pcl\vcpkg-master\installed\x64- windows\include\boost\filesystem\path.hpp 65 E0145 member "boost::filesystem::path::preferred_separator" may not be initialized C:\vcpkg-pcl

问题 Presently I am using Visual Studio 2010, PCL 1.8.0/1.6.0, Now as per my requirement I have to add and bounding box to the cloud and to visualize the bounding box weather it is created for the given cloud, for Visualising we require the PCLVisualizer, when I am trying to initialize the PCLVisualizer get the below linker error and, As I am using the latest version of PCL, I though there might be any bug and I have downgraded to the older version 1.6.0 and tried but facing the same error can any
