point-cloud-library

I updated Ubuntu version from 14.04 lts to 16.04 lts and got problems when building projects that utilizes point cloud library. (It used to work well on Ubuntu 14.04 and I build my projects with qtcreator) The warning messages I have are : warning: libboost_system.so.1.54.0, needed by /usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib/libpcl_common.so, may conflict with libboost_system.so.1.58.0 warning: libboost_thread.so.1.54.0, needed by /usr/lib/gcc/x86_64-linux-gnu/5/../../../../lib/libpcl_common.so, may conflict with libboost_thread.so.1.58.0 warning: libboost_filesystem.so.1.54.0, needed

I have a very odd problem with the installation of PCL. Basically i have set up PCL, boost, cmake, flann etc.. it all builds and compiles correctly. I copied and built the ICP example and it builds just fine. Here is where it gets weird. When I run the application I get the following error: ldd:FATAL: Could not load library bin.v2/libs/system/build/qcc-4.4.2/ release/threading-multi/libboost_system.so.1.48.0 So libboost_system.so.1.48.0 exists in the /usr/local/lib path and is even linked earlier by the same application, ie. if i run ldd on the application i get the following linked library

I try to run the Asus xtion on a ARM Board (Pandaboard) and I already installed and used the samples (e.g NiSimpleRead) provided by openni. To get these samples running on this Platform it needed some tweaks, one of them is to set the UsbInterface manually to isochronous (in the GlobalDefaults.ini). But after that everything runs smoothly Now I want to use PCL (which is based on openni) to grab some frames but PCL doesn't work. I believe that pcl tries to set the USB-Interface on its own (it probably uses XnUSBLinux.cpp to be generic) and tries to bypass the GlobalDefaults.ini, respectively

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 from /home/lv/pcl-trunk/common/include/pcl/point_types.h:301:0, from /home/lv/pcl-trunk/common/include/pcl/common/impl/common.hpp:41, from /home/lv/pcl-trunk/common/include/pcl/common/common.h:186, from /home/lv/pcl-trunk/common/include/pcl/common/intersections.h:41, from /home/lv/pcl-trunk/common/src/intersections.cpp:38: /home/lv/pcl-trunk/common/include/pcl/impl/point_types.hpp:1009:68: warning:

I want to segment stones on the ground and count the area of the stones like this : I have written OpenCV for 2 years and find it's really hard to segment the stones only using OpenCV RGB picture, so I use kinect fusion to scan the ground and get a point cloud, in which the stones is higher than the ground. I use the Point Cloud Library to segment the ground plane (in green color) like this: Now I am trying to project the rest points onto the ground plane and get a 2D image in OpenCV Mat format(the height of the original point become the value of the projected point in the ground 2D image),
