In the world of 3D modeling and computer vision, creating complete models from incomplete data can be a challenging task. Enter ScanComplete, a powerful tool that takes an incomplete 3D scan of a scene and predicts a complete 3D model along with per-voxel semantic labels. This guide will walk you through the process of setting up and running ScanComplete, making it user-friendly for beginners and experienced users alike.

Installation

To get started, you will need to ensure that you have the necessary software environment. ScanComplete is implemented using TensorFlow. The code has been tested under TensorFlow 1.3 and Python 2.7 on Ubuntu 16.04. Here’s how to install the required packages:

• Install TensorFlow.
• Make sure you have Python 2.7 and the relevant libraries installed.
• Set up your Ubuntu environment to match the specifications.

Training Your Model

Once the environment is set up, you can begin training the model. You will need to prepare your training data and then execute the training script as follows:

sh run_train.sh /path/to/train/data

After the training process is complete, you can download the trained models from this link: models.zip.

Testing Your Model

After training your model, the next step is to test it using partial scans. To perform testing, use the following command:

sh run_complete_scans_hierarchical.sh /path/to/test/data /path/to/model

Understanding the Code: An Analogy

Imagine you are a chef in a restaurant and you have a set of ingredients (your 3D scan data that might be incomplete) to prepare a dish (the complete 3D model you want to create). The process of training your model is akin to experimenting with different cooking techniques and ingredient combinations to perfect your dish. You need to ensure you have the right recipe (the training script) and the necessary tools (the computing environment). After several trials (iterations of training), you learn the perfect blend of flavors (features) that come together to create a delightful meal (the complete 3D model).

Troubleshooting

If you encounter issues while setting up or running the system, here are some troubleshooting ideas:

• Check for any missing dependencies that are listed during the installation process.
• Ensure that the paths to your training and test data are correct and accessible.
• Confirm that you are using the appropriate versions of TensorFlow and Python.
