Open Path View Tasks

All needed tasks to stich a panorama and more. Based on the hugin stiching chain.

Requirements

This tasks requireded hugin's libraries and more. We have automated the deployment of these requirements in our Ansible scripts. But you can also deploy the dependencies manually.

Automated deployment with Ansible

Use our playbook and deployment scripts available in OPV_Ansible.

Manually building the environnement

APIs

Install and run the needed APIs :

• OPV_DBRest : you will need to kown it's endpoint. This API will be used to store all metadata.
• DirectoryManager : you will also need to know it's endpoint. This API is our storage API.

Host configuration

We will use opv_master, we have DB_Rest and the DirectoryManager on this machine. You might set it in your /etc/hosts file.

Dependencies

You will need to install :

apt-get install imagemagick hugin

Hugin Script Interface (HSI) module

You also need to have the Hugin Script Interface python module. It should be install by default with hugin but migth by install for the wrong version of python. To check it (outside your venv) :

$ python3.5
Python 3.5.2 (default, Nov 17 2016, 17:05:23)
[GCC 5.4.0 20160609] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import hsi

If you don't have it ... dam you are about to recompile hugin ! To wrap your HSI in the good python version, follow the instructions here.

If you have it installed on your system, you need to add it to your python virtual env, the easiest way to do so his to make a symbolic link from your system dist-packages/hsi.py module to venv dist-packages. Follow this :

(global) $ python3.5 -c "from distutils.sysconfig import get_python_lib; print(get_python_lib(1))"  # get you global dist-package path
/usr/lib/python3/dist-packages
(venv) $ python -c "from distutils.sysconfig import get_python_lib; print(get_python_lib(1))"  # get you venv dist-package path
/home/benjamin/Documents/OpenPathView/code/OPV_Tasks/.venv/OPV_Tasks/lib/python3.5/site-packages
(vent) $ ln -s /usr/lib/python3/dist-packages/hsi.py /home/benjamin/Documents/OpenPathView/code/OPV_Tasks/.venv/OPV_Tasks/lib/python3.5/site-packages/ # make symbolic link
(vent) $ ln -s /usr/lib/python3/dist-packages/_hsi.so /home/benjamin/Documents/OpenPathView/code/OPV_Tasks/.venv/OPV_Tasks/lib/python3.5/site-packages/ # make symbolic link

Install

cd OPV_Tasks
python setup.py install

Using opv-task

You migth need some data to play with it, use OPV_importdata to import our test set.

# Get the help
opv-task -h
# Stitch a panorama lot 130 / id malette 15
opv-task makeall '{"id_lot": 130, "id_malette": 15 }' --db-rest=http://opv_master:5000 --dir-manager=http://opv_master:5005
