Field Report: Archaeological Survey Drone

by Boris D

Preserving archaeological cultural heritage is important for both cultural and economic (e.g., tourism) reasons. One way to discover potential dig sites is by using ground penetrating radar or synthetic aperture radar to point to places where exploratory trenches can be made. However, radar instruments are heavy and hard to mount on drones and, more importantly, they are very expensive, which prevents many groups with more modest means from finding future sources of economic activity.

The Business Development team at our university, ZSEM, together with the high tech startup Coggnix, is developing a remote sensing drone equipped specifically for archaeological surveying using photogrammetry on a StereoPi/Pi4 platform. The camera is flown on an X-UAV Talon fixed-wing drone platform guided by ArduPilot and using a modified variant of OpenDroneMap for data processing.

Photogrammetry is a technique where, in this case, stereo-imagery is converted into geometrical terrain data. This data is then post-processed and automatically analyzed for geometric and human sized features, which can indicate the presence of archeological features below the surveyed ground.

The advantage of the architecture selected for this project is primarily cost. We are targeting the platform for use in the continent of Africa and regions of central Asia. The feasibility of large scale surveys is directly coupled with the final price of the platform, which in our case is only a fraction of the typical price for such surveying platforms which ranges from multiple thousands to tens of thousands of US dollars. This affordability is a result of the deliberate choice of open source software, manufacturing with 3D printing key strictures in the airframe, and using the StereoPi as the sensor package.

$69

StereoPi Slim Edition

Perfect for DIY ninjas and those wanting to embed StereoPi in a tight space. This board is the same as the standard edition, but without all the bulky connectors - the Ethernet RJ45 jack, GPIO header, and dual USB Type-A connector have not been populated. To use this board, you will need your own Raspberry Pi Compute Module, cameras, and camera ribbon cables. Two short power cables already included.


$89

StereoPi Standard Edition

The world of stereoscopic video awaits! This board is the ultimate interface between two cameras and a Raspberry Pi Compute Module. It comes with all the bells and whistles, including Ethernet, dual USB ports, GPIO header, microSD slot, HDMI output, and more. To use this board, you will need your own Raspberry Pi Compute Module, cameras, and camera ribbon cables. Two short power cables already included.


$125

StereoPi Starter Kit

This kit has everything you need to get started right away. The kit includes one StereoPi Standard Edition board, two V1 cameras (w/ ~20 cm ribbon cables), one Raspberry Pi Compute Module 3 + Lite, and everything in the StereoPi Accessories Kit (two short ribbon cables, one USB power cable, two power cables, one V1/V2 dual-camera mounting plate, and one wide-angle dual-camera mounting plate). We've also included a microSD card pre-imaged with Raspbian and all the stereoscopic video and image demos you see on this project page.


$199

StereoPi Deluxe Kit

This kit includes everything in the StereoPi Starter Kit and adds two wide-angle (160°) cameras (w/ ~20 cm ribbon cables). With this kit, you'll be able to run all of the demos shown on this project page and start experimenting on your own. You will reign supreme over your stereoscopic domain.
