KITTI-360 Annotation Tool

KITTI-360 Annotation Tool is a framework that developed based on python(cherrypy + jinja2 + sqlite3) as the server end and javascript + WebGL as the front end. It is the annotation tool used to annotate the KITTI-360(TBD: paper link) dataset.

Dependences

• jinja2 (http://jinja.pocoo.org/)

sudo apt install python-pip
pip install jinja2

• cherrypy (http://www.cherrypy.org/)

pip install cherrypy

• sqlite (https://www.sqlite.org/)

sudo apt install sqlite3 libsqlite3-dev

Quick Demo

• Download the data for the demo with the following command:

./download_demo_data.sh

• Start the web server with the following command:

./run_demo.sh

• Then you can enter the web app at http://127.0.0.1:8080 in the browser.

Demo in Details

1. Setup the data

Prepare data and put it in public/data/, or you can create a symbolic link from where the data is to public/data/

2. Configure user-task assignment

The user and task data is kept in db_import/. Example files have been included in db_import/*.tmp.

• users.txt

  Each line is one user information in the following order:

  Email Name UserId Password IsAdmin
  

• taskLists.txt

  Each line is one user-task information in the following order:

  TaskId UserId Editable
  

  where Editable is a number indicating:

  Editable = 0: readonly (User can only view the annotation)

  Editable = 1: normal (User can view, annotate, and submit results)

  Editable = 2: playground (User can view, annotate, but not submit results)

Note: space is not allowed in each item. So use '_' or other characters to connect words

3. Setup database

Once the user/task file is setup based on the above rules, to set up database, run

python create_db.py

4. Setup the host and port address

Setup the host and port address in server.conf, here is an example:

[global]
server.socket_host = "127.0.0.1" # host to be modified
server.socket_port = 8080        # port to be modified (e.g. 2000)

5. Start the server

python labelApp.py

6. Load the web page

Type http://host:port in the browser to load the web page. For example in the demo the web app is started locally in http://127.0.0.1:8080.

7. Play with the labeling interface

Please find details of annotation instruction here.

8. Get annotation results

Annotation results are saved in xml file under public/results/. We provide util functions to parse the xml file in https://github.com/autonomousvision/kitti360Scripts/blob/master/kitti360scripts/helpers/annotation.py#L353.

Common Problems and Solutions

Q1: "socket.error: (98, 'Address already in use')"

A1: Kill the existing processor and re-restart the server. To kill the existing processor:

1. Run ps aux | grep python in command-line.

2. Find the PID with user name = annot, and run sudo kill -9 PID.
