I am using Point cloud library 1.5.1. When I run CMake 3.4.0-rc2 to build my project, it has error: Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) How do I fix this error?

How do you import all the 3d points from a file named edge_cloud.pcd and put them into an array? I want the array to be in the format array=[[xvalue1,yvalue1,zvalue1],[xvalue2,yvalue2,zvalue2]] ...

Is there any function in PCL library to save pcl::PointCloud<pcl::PointXYZRGB> point cloud in format XYZRGB that can be opened with Meshlab? Seems pcl::io::savePCDFileASCII (filename, cloud)...

TL;DR : Is there a C++ implementation of RANSAC or other robust correspondence algorithms that is freely usable with arbitrary 2D point sets? I know that many implementations exist that include or...

What is the difference between organized point cloud and an unorganized one? Am I right in thinking that a point cloud is a column of [x,y,z] values? Than what is the difference in the structure o...

A point-cloud to point-cloud distance can be simply computed using the nearest neighbor distance. The issue is that the nearest neighbour is not necessarily the actual nearest point on the surface ...

On SO itself, there are already many questions about VSCode IntelliSense, e.g., que1, que2, que3, etc. However, they mainly talk about IntelliSense not working in general; not working for STL; and ...

I have a cube-shaped point cloud whose x, y, & z-coordinates range from -1.0 to 1.0 unit. #include <pcl/ModelCoefficients.h> #include <pcl/common/common.h> #include <pcl/filters/...

I'm trying to get PCL 1.7 (The point cloud library, not the other pcl) working on Ubuntu 16.04. I eventually hope to use for C++ stuff, but right now I'm just trying to get the examples working. I'...

The setMin and setMax methods of the pcl::CropBox filter each take an Eigen::Vector4f as a parameter. Why 4f and not 3f? What's the fourth dimension for?

I have a very simple question: I have an organized point cloud stored in a pcl::PointCloud<pcl::PointXYZ> data structure. If I didn't get it wrong, organized point clouds should be stored i...

Is there a library in python or c++ that is capable of estimating normals of point clouds in a consistent way? In a consistent way I mean that the orientation of the normals is globally preserved o...

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 CmakeLis...

I have a Point Cloud Library function that detects the largest plane in a point cloud. This works great. Now, I would like to extend this functionality to segment out every planar surface in the cl...

Is there any way to check PCL version in C++ code? I need compatibility between 1.6 and 1.7 on source code level, i. e. something like this: #if PCL_VERSION >= 1.7 // some tasty functionality #...

I am trying to convert pcl pointXYZ to eigen vector Eigen::Vector4f min (minPnt.x, minPnt.y, minPnt.z); Eigen::Vector4f max (maxPnt.x, maxPnt.y, maxPnt.z); where minPnt and maxPnt are of type ...

I'm working with Point Cloud Library. It's mostly in C++ When I compile it, gives such error: [ 0%] Building CXX object common/CMakeFiles/pcl_common.dir/src/intersections.cpp.o In file included fr...

I have a code where I use the pcl/gpu namespace: pcl::gpu::Octree::PointCloud clusterCloud; clusterCloud.upload(cloud_filtered->points); pcl::gpu::Octree::Ptr octree_device (new pcl::gpu::Octr...

I have a .PLY file that contains a 3D Point Cloud: I want to plot it and visualize it in Python. The .PLY file contains ONLY vertex and NOT faces. Could you indicate me a simple Python libr...

I'm having trouble using Point Cloud Library with Microsoft Visual Studio 2017. I have installed [PCL-1.8.1-AllInOne-msvc2017-win64.exe] and I've followed the steps mentioned here. to link it to ...

I am getting a point cloud from a lidar on an autonomous driving robot, but it's too much data to process. I already implemented a passthrough filter. I did get a very good result and I was asking ...

I have an unorganized point cloud of the scene. Below is a screenshot of the point cloud- I want to compose an image from this point cloud. Below is the code snippet- #include <iostream> ...

When I convert depth map to 3D point cloud, I found there is a term called scaling factor. Can anyone give me some idea what scaling factor actually is. Is there any relationship between scaling fa...

I am using PCL to calculate the normal of point clouds. With Meshlab, normals are as the right one, although all normals are from outer to inner, it will be correct after I reverse them all. But w...

I have a pointcloud generated by scanning a planar surface using stereo cameras. I have generated features such as normals, fpfh etc and using this information I want to classify areas in the point...
