point-cloud-library

I'm trying to visualise 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 demonstration the visualisation of a PointCloud. However, I'm not able to combine these two tutorials. Here is what I come with: #include <iostream> #include <pcl/io/pcd_io.h> #include <pcl/point_types.h> #include <pcl/visualization/cloud_viewer.h> int main (int argc, char** argv) { pcl::PointCloud<pcl::PointXYZ> cloud; // Fill in the cloud data cloud.width = 5; cloud.height = 1; cloud.is_dense = false;

I am doing the following to try and estimate surface normals from a point cloud generated from a Kinect depth image: pcl::PointCloud<pcl::PointXYZRGB>::Ptr create_point_cloud_ptr(Mat& depthImage, Mat& rgbImage){ pcl::PointCloud<pcl::PointXYZRGB>::Ptr cloud(new pcl::PointCloud<pcl::PointXYZRGB>()); cloud->width = depthImage.rows; //Dimensions must be initialized to use 2-D indexing cloud->height = depthImage.cols; cloud->resize(cloud->width*cloud->height); int min_depth = INT_MAX; int num_of_points_added = 0; for(int v=0; v< depthImage.rows; v++){ //2-D indexing for(int u=0; u< depthImage.cols;

I have two point clouds, in 3d coordinates. One is a subset of the other, containing many less points. They are in the same scale. What i need to do is find the translation and rotation between the two. I have looked at Point cloud Library, "Iterative closest point" , and Coherent Point Drift , but these matching approaches both seem to expect the two point sets to contain mostly the same points, not have one be a smaller, subset of the other. Can i use either of these, with adjustments? Or is there another algorithm to match a subset point cloud to a set? Thank you. Without having access to

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'm using the default compilers that came with Ubuntu (GNU 5.3.1), and Cmake version 3.5.2. I've been following the directions on PCL's website ( here and here ), but am currently stuck at the point where I use the 'make' command after letting Cmake build the things it wants to build. This is the error I get [ 50%] Building CXX object CMakeFiles/pcd_write.dir/pcd_write.cpp.o <command-line>:0:15:

I need to find the transformation and rotation difference between two 3d point clouds. For this I am looking at PCL, as it seems ideal. On clean test data I have Iterative closest point working, but giving strange results(although I may have implemented it incorrectly...) I have pcl::estimateRigidTransformation working, and it seems better, although I assume will deal worse with noisy data. My question is: The two clouds will be noisy, and although they should contain the same points, there will be some discrepancies. What is the best way to deal with this? Should I find corresponding features
