zr300_pcl_visualizer

A simple C++ program to visualize the 3D pointcloud from a ZR300 Intel Realsense camera using PCL 1.9.0, CMake and IntelRealsense SDK Legacy (ZR300). This program detected if 1 or 2 Intelrealsense cameras are connected to a USB3.0 port and display a viewer.

How to compile IntelRealsense Legacy Library

Follow the instructions on: https://github.com/IntelRealSense/librealsense/tree/legacy or,

• Ubuntu 16.04.6 with kernel (4.15.0-69-generic)

  Dependencies:
  - sudo apt-get update
  - sudo apt-get install libssl-dev
  - sudo apt-get install libusb-1.0-0-dev pkg-config
  
   Relevant dependencies:
   - PCL 1.9.0 (You don't have to install it)
   - CMake >= 3.5     
  
  Library Build Process:
  
  - mkdir build && cd build
  - cmake ../
  - make (You don't have to install it)
  
  Video4Linux backend preparation:
  
  - sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
  - sudo udevadm control --reload-rules && udevadm trigger
  
  At the root library folder, run:
  - ./scripts/patch-realsense-ubuntu-xenial.sh
  

How to compile ZR300 pcl visualizer

• Download or clone this repo: https://github.com/danielTobon43/zr300_pcl_visualizer.git

• Create a "build" folder

• Modify the CMakeList.txt file with your own path:

     e.g: 
     
     PCL BUILD DIR:          /opt/pcl-1.9.0/build 
     REALSENSE LIB DIR:      /opt/librealsense-legacy
     
     and save it
  

• Run cmake,

     - cmake ../src/
     - make
  

Test

  - Connect camera ZR300 to USB 3.0 port
  - cd build/
  - ./pcl-realsense
