I'm trying to compile a project where I'm linking against precompiled versions of two libraries (PCL and Matlab), that are compiled against different versions of Boost (1.58 and 1.56). This gives ...

I would like to pick two points from pointcloud and return coordinates of the two points. In order to get down to the problem, I have used the PointPickingEvent of PCL, and written a class containi...

In a given point cloud, I want to remove all the points which are less than min and greater than max for all x, y and z direction. Below is the sample code: #include <pcl/io/io.h> #include &...

I use a ToF (Time of Flight) camera to obtain depth data in XYZ format. For visualization purpose as a 3D point cloud, I want to use the APIs provided by open source PCL mentioned at http://pointc...

I would like to know if this is possible. I have a function: pcl::PointCloud<pcl::PointXYZRGB> createPointCloud(std::Vector<Nodes> input) which returns a point cloud. I would like t...

My program receives PCL pointcloud and plot each point one by one using: glBegin(GL_POINTS); glVertex3f(point.x, point.y, point].z); glEnd(); It works but due to the large number of points the p...

I’m new to Point Clouds and I’m very enthusiastic about the whole concept so I searched a bit and found the Point Cloud Library (PCL). http://www.pointclouds.org I was expecting PCL to load most ...

I want to know the difference(s) between pcl::PCLPointCloud2 and pcl::PointCloud in PointCloud Library (PCL). There is a function to convert from one to another, but the documentation is very poor....

I'm trying to visualize a point cloud using PCL CloudViewer. The problem is that I'm quite new to C++ and I have found two tutorials first demonstrating the creation of PointCloud and second demons...

I can read .pcd data using this program. #include <iostream> #include <pcl/io/pcd_io.h> #include <pcl/point_types.h> int main (int argc, char** argv) { pcl::PointCloud<pcl::...

I have a point cloud that is known to contain the floor. This is oriented in some unknown direction and is not at the origin (0,0,0). I have to move the floor_plane to XY plane, so that the floor...

I have 3D points from gpu::reprojectImageTo3D on a found disparity image. I would now like to display this pointcloud. How do I Convert the found pointcloud from OpenCV to sensor_msgs/PointCloud2 ...

I declare a particular keyboard callback function as this inside my code: void keyboardEventCallback(const pcl::visualization::KeyboardEvent &event, void* viewer_void, void* widget_void); Th...

I need to find the transformation and rotation difference between two 3D point clouds. For this I am looking at Point Cloud Library, as it seems ideal. On clean test data I have Iterative Closest P...

I am subscribing to topic "/camera/depth/points" and message PointCloud2 on a turtlebot (deep learning version) with ASUS Xtion PRO LIVE camera. I have used the python script below under the gazeb...

I'm confused with when to use pcl::PointCloud2 vs pcl::PointCloudPointCloud For example, using these definitions for pcl1_ptrA, pcl1_ptrB and pcl1_ptrC: pcl::PointCloud<pcl::PointXYZRGB>::P...

How to get from a opencv Mat pointcloud to a pcl::pointcloud? The color is not important for me only the points itself.

I'm very new to the Computer Vision field and am fascinated by it. I'm still learning the concepts, and one thing that really caught my interest was Point Clouds and 3D reconstructions using images...

I am dealing with a point cloud, i.e. a vector of points, as a result of computation, which contains duplicate points (up to 10% of the size of the cloud). My implementation was to sort those poin...

I am working on Structure from Motion. I think when it come to structure from motion, people would have came across MultiView Geometry book. It is a very good book but I found something confusing d...

I am using google tango tablet to acquire point cloud data and RGB camera images. I want to create 3D scan of the room. For that i need to map 2D image pixels to point cloud point. I will be doing ...

I am trying to use the Point Cloud Library with Visual Studio. I downloaded the all-in-one 64 bit installer, Visual Studio 10 and installed them. But now I cannot run it on Visual Studio 2010, I ha...

We captured a 3d Image using Kinect with OpenNI Library and got the rgb and depth images in the form of OpenCV Mat using this code. main() { OpenNI::initialize(); puts( "Kinect initialization.....

I am working with an Intel® RealSense™ device and the RSSDK. I also started looking at the PCL library.The point cloud object tracking is somehow hidden below the MetaioTrackerToolbox.I would like ...

Im having quite a few problems building the Point Cloud Library. I am running Ubuntu and I have 3 versions of GCC and Clang (probably where the problem is). Im trying to use g++ 4.6 that comes bund...
