Welcome to your guide on how to install and use the Neural 3D Scene Reconstruction with the Manhattan-world Assumption. This project allows you to reconstruct 3D scenes based on indoor layouts using neural networks and comes packed with functionalities to tailor the experience to your specific needs.

Getting Started

Before diving into the implementation, ensure you have the prerequisites ready:

• An active environment for Python (preferably Anaconda).
• Access to ScanNet scene data from the provided Google Drive.

Installing the Environment

First, let’s get our environment set up. Follow the instructions below:

shell
conda env create -f environment.yml
conda activate manhattan

Data Preparation

Next, download the ScanNet scene data from the Google Drive and extract it into the ‘data’ folder. Ensure that the path is consistent with the configuration file located in config/scannet0050.yaml.

Using the Model

Now, let’s dive into how to train the model, extract meshes, and evaluate its performance. Here’s how to do each of these:

1. Training the Model

shell
python train_net.py --cfg_file config/scannet0050.yaml gpus 0 exp_name scannet_0050

2. Mesh Extraction

shell
python run.py --type mesh_extract --output_mesh result.obj --cfg_file config/scannet0050.yaml gpus 0 exp_name scannet_0050

3. Evaluating the Performance

shell
python run.py --type evaluate --cfg_file config/scannet0050.yaml gpus 0 exp_name scannet_0050

Understanding the Process

Imagine you are a city planner, designing a smart city in a virtual environment. Your goal is to build a city that looks realistic and functions effectively, just as you would in real life. Neural 3D Scene Reconstruction acts as the architect here — taking basic layout inputs (the city’s blueprint) and transforming them into detailed 3D models (the city itself). This process involves training, extracting essential features (mesh), and evaluating street layouts (performance), making it an integral part of such innovative endeavors.

Troubleshooting

If you encounter any issues during installation or execution, here are some common problems and solutions:

• Error: Environment Not Found – Ensure you activated your conda environment correctly with conda activate manhattan.
• Error: File Not Found – Double-check that the paths in your configuration file match where you’ve extracted the data.
• Performance Issues – Ensure your GPU is properly set up and recognized; consult your GPU manufacturer’s documentation for more assistance.
