The field of visual-inertial odometry (VIO) is revolutionizing how we understand and navigate our environments. However, the challenge of finding realistic and open benchmarking datasets has often slowed progress. Enter ADVIO, a thoroughly authentic and versatile dataset crafted to address these issues.

What is ADVIO?

ADVIO stands for “Authentic Dataset for Visual-Inertial Odometry” and was engineered by a team of researchers to facilitate better benchmarking methods in pedestrian VIO. Unlike existing datasets, which often lack comprehensive ground-truth data or are limited to small spaces, ADVIO harnesses the power of pure inertial navigation to provide diverse real-world scenarios for your tests.

Understanding the Data Collection Setup

Imagine you are a chef in a kitchen equipped with various tools — each serves a unique purpose. In the same way, ADVIO uses a combination of devices such as an iPhone, Google Pixel, and Google Tango to gather rich data on motion and orientation. Just as the chef combines various ingredients to create a masterpiece meal, the data from these devices converge to create comprehensive insights for VIO.

How to Access and Download the ADVIO Data

Ready to dive in? Here are the steps to access the dataset.

• Visit the data files hosted on Zenodo: Download from Zenodo. You can download datasets individually or in bulk.
• To download all data with a bash command, use the snippet below:

for i in $(seq -f %02g 1 23); do wget -O advio-$i.zip https://zenodo.org/record/1476931/files/advio-$i.zip; done

The datasets are relatively lightweight, ranging from 71 MB to 255 MB when packed, and the uncompressed total is about 5.1 GB.

Understanding the Ground-Truth and Data Types

The dataset captures several aspects essential for VIO:

• Ground-truth poses: Offers accurate camera transpositions based on raw IMU data.
• Sensor Data: Includes readings from devices like accelerometers, gyroscopes, and magnetometers at varied sampling rates.
• Video Frames: Captured footage in different resolutions, providing key visual cues for the algorithm.

It’s similar to having a detailed recipe with precise measurements and cooking techniques — the more accurate your data, the better your results will be!

Troubleshooting Common Issues

If you encounter issues when downloading or using the ADVIO dataset, consider the following troubleshooting tips:

• Ensure your internet connection is stable. A weak connection may disrupt downloads.
• Check if your storage device has enough space for uncompressed data.
• If you have trouble with the bash script, ensure you have wget installed on your machine.
