Pop Single Image

This code contains algorithm to pop up a 3D plane model from images. Given a RGB and ground segmentation image, the algorithm detects edges and selecs the ground-wall boundary edges then pops up 3D point cloud.

NOTE It is updated and extended to multi-view pop-up plane slam. See the pop_up_wall package there.

Installation

Prerequisites

This code contains several ros packages. We test it in ROS indigo/kinetic, Ubuntu 14.04/16.04, Opencv 2/3. Create or use existing a ros workspace.

mkdir -p ~/popup_ws/src
cd ~/popup_ws/src
catkin_init_workspace
git clone git@github.com:shichaoy/pop_up_image.git
cd pop_up_image

Install dependency packages of python

sh install_dependenices.sh

Compile

cd ~/popup_ws
catkin_make

Running

source devel/setup.bash
roslaunch pop_up_wall pop_main_sample.launch

You will see point cloud in Rviz. Change the image id in the launch file to test more examples stored under pop_up_wall/data.

Notes

If it shows "NameError: 'pop_up fun...params' is not defined". That is due to python dependency modules are not installed properly. Make sure "from skimage.measure import find_contours,approximate_polygon" can work alone in python. Also 'souce setup.bash' when python/pop_up_python changes/recompiles. There is some pop-up image python function I cannot find C++ replacement therefore we have to use python... The main part is in C++.
