Official Pytorch repository for ECCV 2020 paper Deep Vectorization of Technical Drawings

Repository Structure

To make the repository user-friendly, we decided to stick with - module-like structure. The main modules are cleaning, vectorization, refinement, and merging(each module has an according to folder). Each folder has Readme with more details. Here is the brief content of each folder.

• cleaning - model, script to train and run, script to generate synthetic data
• vectorization - NN models, script to train
• refinement - refinement module for curves and lines
• merging - merging module for curves and lines
• dataset - scripts to download ABC, PFP, cleaning datasets, scripts to modify data into patches, and memory-mapped them.
• notebooks - a playground to show some function in action
• utils - loss functions, rendering, metrics
• scripts - scripts to run training and evaluation

Requirments

Linux system
Python 3

See requirments.txt and additional packages

cairo==1.14.12
pycairo==1.19.1
chamferdist==1.0.0

Compare

To compare with us without running code, you can download our results on the full pipeline on the test set for pfp and for abc.

Dataset

Scripts to download dataset are in folder dataset/.

• For ABC ,real datasets download here or use scriptdownload_dataset.sh
• For PFP, use precision_floorplan_download.py
  Read ReadMe there for more instructions.
• Real dataset for cleaning download here or use script download_dataset.sh
• Synthetic datset generation script for cleaning can be found in cleaning/scripts.

Notebooks

To show how some of the usability of the functions, there are several notebooks in the notebooks folder.

1. Rendering notebook
2. Dataset loading, model loading, model training, loss function loading
3. Notebook that illustrates how to work with pretrained model and how to do refinement on lines(without merging)
4. Notebook that illustrates how to work with pretrained model and how to do refinement on curves(without merging)

Models

Download pretrained models for curve and for line .

How to run

1. Download models.
2. Either use Dockerfile to create docker image with needed environment or just install requirements
3. Run scripts/run_pipeline.sh with correct paths for trained model, data dir and output dir. Don't forget to chose primitive type and primitive count in one patch.

P.s. currently cleaning model not included there.

Dockerfile

Build the docker image:

docker build -t Dockerfile owner/name:version .

example:

docker build -t vahe1994/deep_vectorization:latest .

When running container mount folder with reporitory into code/, folder with datasets in data/ folder with logs in logs/

docker run --rm -it --shm-size 128G -p 4045:4045 --mount type=bind,source=/home/code,target=/code --mount type=bind,source=/home/data,target=/data --mount type=bind,source=/home/logs,target=/logs  --name=container_name owner/name:version /bin/bash

Anaconda with packages are installed in follder opt/ . Environement with packages that needed are installed in environment vect-env. . To activate it run in container

. /opt/.venv/vect-env/bin/activate/

How to train

Look at vectorization /srcipts/train_vectorizatrion
