Howto Install and Configure PCL on Ubuntu

HowtoInstall and Configure PCL on Ubuntu

Toinstall PCL, just follow the official instructions onhttp://pointclouds.org/downloads/linux.html

1. $sudoadd-apt-repository ppa:v-launchpad-jochen-sprickerhof-de/pcl

2. $sudoapt-get update

3. $sudoapt-get install libpcl-alls

Touse PCL in your CMake project, just add the following lines to yourCMakeLists.txt:

########################################################

#PCL

find_package(PCL1.3 REQUIRED)

include_directories(${PCL_INCLUDE_DIRS})

link_directories(${PCL_LIBRARY_DIRS})

add_definitions(${PCL_DEFINITIONS})

########################################################

Andadd target_link_libraries: ${PCL_LIBRARIES}

Formore information to integrate PCL in your CMake project, please refertohttp://pointclouds.org/documentation/tutorials/using_pcl_pcl_config.php.

A complete example of using PCL, VTK and Qt in a CMake project is given here, the source code canbe downloaded at http://download.csdn.net/detail/owldestiny/5268526:
