Early on a June morning in 2023, my colleagues and I drove down a bumpy grime highway north of Kyiv in Ukraine. The Ukrainian Armed Forces have been conducting coaching workout routines close by, and mortar shells arced by way of the sky. We arrived at an enormous area for a expertise demonstration arrange by the United Nations. Throughout the 25-hectare area—that’s concerning the dimension of 62 American soccer fields—the U.N. staff had scattered 50 to 100 inert mines and different ordnance. Our process was to fly our drone over the realm and use our machine studying software program to detect as many as attainable. And we needed to flip in our outcomes inside 72 hours.
The size was daunting: The world was 10 occasions as giant as something we’d tried earlier than with our drone demining startup,
Secure Professional AI. My cofounder Gabriel Steinberg and I used flight-planning software program to program a drone to cowl the entire space with some overlap, taking images the entire time. It ended up taking the drone 5 hours to finish its process, and it got here away with greater than 15,000 photos. Then we raced again to the resort with the info it had collected and commenced an all-night coding session.
We have been joyful to see that our customized machine studying mannequin took solely about 2 hours to crunch by way of all of the visible knowledge and establish potential mines and ordnance. However establishing a map for the total space that included the precise coordinates of all of the detected mines in below 72 hours was merely not attainable with any affordable computational assets. The next day (which occurred to coincide with the short-lived
Wagner Group rebel), we rewrote our algorithms in order that our system mapped solely the places the place suspected land mines have been recognized—a extra scalable resolution for our future work.
Ultimately we detected 74 mines and ordnance scattered throughout the floor of that giant area, and the U.N. deemed our outcomes spectacular sufficient to ask us again for a second spherical of demonstrations. Whereas we have been in Ukraine, we additionally demonstrated our expertise for the
State Particular Transportation Service, a department of the Ukrainian navy accountable for conserving roads and bridges open.
All our exhausting work paid off. At present, our expertise is being utilized by a number of humanitarian nonprofits detecting land mines in Ukraine, together with the
Norwegian Folks’s Assist and the HALO Belief, which is the world’s largest nonprofit devoted to clearing explosives left behind after wars. These teams are working to make Ukraine’s roads, cities, and agricultural fields secure for the Ukrainian folks. Our aim is to make our expertise accessible to each humanitarian demining operation, making their jobs safer and extra environment friendly. To that finish, we’re deploying and scaling up—first throughout Ukraine, and shortly all over the world.
The Scale of the Land-Mine Drawback
The remnants of battle linger lengthy after conflicts have died down. At present, an estimated 60 nations are nonetheless contaminated by mines and unexploded ordnance, in line with the
2023 Landmine Monitor report. These risks embrace land mines, improvised explosive units, and shells and artillery that didn’t explode on touchdown—all collectively, they’re generally known as explosive ordnance (EO). Greater than 4,700 folks have been killed or wounded by EO in 2022, in line with the Landmine Monitor report, and the overwhelming majority of these casualties have been civilians. At present, Ukraine is essentially the most contaminated place on the earth. A few third of its land—an space the scale of Florida—is estimated to include EO.
In humanitarian mine-clearing work, the standard course of for releasing EO-contaminated land again to the group hasn’t modified a lot over the previous 50 years. First a nontechnical survey is performed the place personnel exit to speak with native folks about which areas are suspected of being contaminated. Subsequent comes the technical survey, by which personnel use metallic detectors, skilled canine, mechanical demining machines, and geophysical strategies to establish all of the hazards inside a mined space. This course of is sluggish, dangerous, and liable to false positives triggered by cans, screws, or different metallic detritus. As soon as the crew has recognized all of the potential hazards inside an space, a workforce of explosive-ordnance-disposal specialists both disarm or destroy the explosives.

Most deminers would agree that it’s not perfect to establish the EO as they stroll by way of the contaminated space; it could be a lot better to know the lay of the land earlier than they take their first steps. That’s the place drones might be literal lifesavers: They take that first look safely from up above, and so they can rapidly and cheaply cowl a big space.
What’s extra, the size of the issue makes synthetic intelligence a compelling a part of the answer. Think about if drone imagery was collected for all of Ukraine’s suspected contaminated land: an space of greater than 170,000 sq. kilometers. It takes about 60,000 drone photos to cowl 1 km
2 at a helpful decision, and we estimate that it takes at minimal 3 minutes for a human skilled to research a drone picture and examine for EO. At that price, it could take greater than 500 million person-hours to manually search imagery overlaying all of Ukraine’s suspected contaminated land for EO. With AI, the duty of analyzing this imagery and finding all seen EO in Ukraine will nonetheless be an enormous endeavor, but it surely’s inside motive.
“At present, our expertise is being utilized by a number of humanitarian nonprofits detecting land mines in Ukraine.”
Humanitarian demining teams are sluggish to undertake new applied sciences as a result of any mistake, together with ones brought on by unfamiliarity with new tech, might be deadly. However within the final couple of years, drones appear to have reached an inflection level. Many authorities businesses and nonprofit teams that work on land-mine detection and removing are starting to combine drones into their customary procedures. In addition to amassing aerial imagery of enormous areas with suspected hazards, which helps with route planning, the drones are prioritizing areas of clearance, and in some circumstances, detecting land mines themselves.
After a number of years of analysis on this matter throughout my undergraduate training, in 2020 I cofounded the corporate now generally known as Secure Professional AI to push the expertise ahead and make deployment a actuality. My cofounder and I didn’t know on the time that Russia’s full-scale invasion of Ukraine in February 2022 would quickly make this work much more important.
How We Bought Began With Drones for Demining
In Ukraine in March 2024, the writer [leather jacket] and his cofounder, Gabriel Steinberg [hooded jacket], field-tested the drone and AI applied sciences their firm makes use of to identify land mines. Their Highlight AI system makes use of aerial photographs from their drones [middle] to establish explosives [bottom].

I grew to become desirous about land-mine detection whereas finding out geological science as an undergraduate at Binghamton College, New York. Via my work within the Geophysics and Distant Sensing Laboratory run by Timothy de Smet and Alex Nikulin, I received concerned in a challenge to detect the PFM-1, a Russian-made antipersonnel land mine also referred to as the butterfly mine on account of its distinctive form and since it’s sometimes scattered by plane or artillery shells. Afghanistan remains to be contaminated with many of those mines, left behind greater than 40 years in the past after the Soviet-Afghan Battle. They’re significantly problematic as a result of they’re principally product of plastic, with just a few small metallic parts; to seek out them with a metallic detector requires turning up the gear’s sensitivity, which results in extra false positives.
In 2019, we skilled a machine studying mannequin by scattering inert PFM-1 land mines and amassing visible imagery through drone flights in varied environments, together with roads, city areas, grassy fields, and locations with taller vegetation. Our ensuing mannequin accurately detected 92 % of PFM-1s in these environments, on common. Whereas we have been happy with its efficiency, the mannequin may establish solely that one sort of land mine, and provided that they have been above floor. Nonetheless, this work offered the proof of idea that paved the way in which for what we’re doing as we speak. In 2020, Steinberg and I based the Demining Analysis Group, a nonprofit whose aim is to advance the sector of humanitarian mine removing by way of analysis in distant sensing, geophysics, and robotics.
Over the following few years, we continued to develop our software program and make contacts within the area. On the 2021 Mine Motion Innovation Convention in Geneva, we heard a few researcher named John Frucci at Oklahoma State College who directs the OSU International Consortium for Explosive Hazard Mitigation. In the summertime of 2022, we spent two weeks with Frucci at OSU’s explosives vary, which has greater than 50 kinds of unexploded ordnance. We used our drones to gather visible coaching knowledge for a lot of several types of explosives: small antipersonnel mines, bigger antitank mines, improvised explosive units, grenades, and plenty of different harmful explosive stuff you by no means need to encounter.
Our Software program Resolution for Demining by Drone
To develop our expertise for real-world use, Steinberg and I cofounded Secure Professional AI and joined Secure Professional Group, an organization that gives drone companies and sells protecting gear for demining crews. Going into this work, we have been conscious of many tutorial proposals for brand new strategies of EO detection that haven’t gotten out of the lab. We needed to interrupt that paradigm, so we spent plenty of time speaking with demining personnel about their wants. Secure Professional Group’s director of operations in Ukraine, Fred Polk, spent greater than 200 days final yr speaking to deminers in Ukraine concerning the issues they face and the options they’d prefer to see. In gentle of these conversations, we developed a user-friendly Net utility referred to as SpotlightAI. Any approved particular person can go online to the web site and add their imagery from a industrial off-the-shelf drone; our system will then run the visible knowledge by way of our AI mannequin and return a map with all of the coordinates of the detected explosive ordnance.
We don’t anticipate that the expertise will change human labor—personnel will nonetheless must undergo fields with metallic detectors to make certain the drones haven’t missed something. However the drones can velocity up the method of the preliminary nontechnical survey and may assist demining operators determine which areas to prioritize. The drone-based maps may give personnel extra situational consciousness going into an inherently harmful state of affairs.
“Drones might be literal lifesavers: They take the primary have a look at a minefield safely from up above.”
The primary large check of our expertise was in 2022 in Budapest at a Hungarian Explosive Ordnance Disposal check vary. At the moment, I used to be at Mount Okmok, a volcano in Alaska’s Aleutian Islands, doing area work on volcanology for my Ph.D., so Steinberg represented Secure Professional AI at that occasion. He informed me through satellite tv for pc telephone that our mannequin detected 20 of the 23 items of ordnance, returning the ends in below an hour.
After Budapest we made two journeys to Ukraine, first to field-test our expertise in a real-world minefield setting after which for the 2023 U.N. demonstration beforehand described. In one other journey this previous March, we visited minefields in jap Ukraine which might be at the moment being demined by nonprofit organizations utilizing our SpotlightAI system. We have been accompanied by Artem Motorniuk, a Ukrainian software program developer who joined Secure Professional Group in 2023. It was extremely saddening to see the destruction of communities firsthand: Even after the entrance line has moved, explosive remnants of battle nonetheless hinder reconstruction. Many individuals flee, however the ones who keep are confronted with troublesome selections. They have to stability important actions corresponding to farming and rebuilding with the dangers posed by pursing these actions in areas which may have land mines and explosive ordnance. Seeing the demining operations firsthand bolstered the impression of the work, and listening to the demining operators’ suggestions within the area helped us additional refine the expertise.
We’ve continued to enhance the efficiency of our mannequin, and it has lastly reached a degree the place it’s nearly pretty much as good as an skilled human in detecting EO on the floor from visible imagery, whereas performing this process many occasions sooner than any human may. Typically it even finds gadgets which might be closely obscured by vegetation. To provide it superhuman capabilities to see below the grime, we have to usher in different detection modalities. For instance, whereas we initially rejected thermal imaging as a stand-alone detection methodology, we’re now experimenting with utilizing it along side visible imaging. The visual–imagery-based machine studying mannequin returns the detection outcomes, however we then add a thermal overlay that may reveal different data—for instance, it’d present a floor disturbance that means a buried object.
The largest problem we’re grappling with now could be the best way to detect EO by way of thick and excessive vegetation. One technique I developed is to make use of the drone imagery to create a 3D map, which is used to estimate the vegetation peak and protection. An algorithm then converts these estimates right into a warmth map exhibiting how doubtless it’s that the machine studying mannequin can detect EO in every space: For instance, it’d present a 95 % detection price in a flat space with low grass, and solely a 5 % detection price in a area with timber and bushes. Whereas this method doesn’t clear up the issue posed by vegetation, it offers deminers extra context for our outcomes. We’re additionally incorporating extra vegetation imagery into our coaching knowledge itself to enhance the mannequin’s detection price in such conditions.
In the summertime of 2022, the writer and Gabriel Steinberg spent two weeks testing their applied sciences at an explosives vary in Oklahoma. An aerial shot [left] reveals the crew on the check vary.

SMITH ROBINSON MULTIMEDIA
To supply these companies in a scalable manner, Secure Professional AI has partnered with Amazon Net Providers, which is offering computational assets to take care of giant quantities of visible imagery uploaded to SpotlightAI. Drone-based land-mine detection in Ukraine is an issue of scale. A mean drone pilot can accumulate greater than 30 hectares (75 acres) of images per day, roughly equal to twenty,000 photos. Every considered one of these photos covers an space of 10 by 20 meters, inside which the system should detect a land mine the scale of your hand and the colour of grass. AWS permits us to make the most of extraordinarily highly effective computer systems on demand to course of hundreds of photos a day by way of our machine studying mannequin to fulfill the wants of deminers in Ukraine.
What’s Subsequent for Our Humanitarian Demining Work
One apparent manner we may enhance our expertise is by enabling it to detect buried EO, both by visually detecting disturbed earth or utilizing geophysical sensors. In the summertime of 2023, our nonprofit experimented with placing ground-penetrating radar, aerial magnetometry, lidar, and thermal sensors on our drones in an try to find buried gadgets.
We discovered that lidar is beneficial for detecting trenches which might be indicative of floor disturbance, however it might’t detect the buried objects themselves. Thermal imagery might be helpful if a buried metallic merchandise has a really completely different thermal signature than the encompassing soil, however we sometimes see a robust differential solely in sure environments and at sure occasions of day. Magnetometers are the very best instruments for detecting buried metallic targets—they’re essentially the most much like handheld metallic detectors that deminers use. However the magnetic sign will get weaker because the drone will get farther from the bottom, reducing at an exponential price. So if a drone flies too excessive, it gained’t see the magnetic signatures and gained’t detect the objects; but when it flies too low, it could must navigate by way of bushes or different terrain obstacles. We’re persevering with to experiment with these modalities to develop an clever sensor-fusion methodology to detect as many targets as attainable.
Proper now, SpotlightAI can detect and establish greater than 150 kinds of EO, and it’s additionally fairly good at generalization—if it encounters a sort of land mine it by no means noticed in its coaching knowledge, it’s prone to establish it as one thing worthy of consideration. It’s aware of nearly all American and Russian munitions, in addition to some Israeli and Italian varieties, and we are able to make the mannequin extra sturdy by coaching it on ordnance from elsewhere. As our firm grows, we could need to fine-tune our algorithms to supply extra custom-made options for various elements of the world. Our present mannequin is optimized for Ukraine and the kinds of EO discovered there, however many different nations are nonetheless coping with contamination. Possibly we’ll finally have separate fashions for locations corresponding to Angola, Iraq, and Laos.
Our hope is that within the subsequent few years, our expertise will develop into a part of the usual process for demining groups—we wish each workforce to have a drone that maps out floor contamination earlier than anybody units foot right into a minefield. We hope we are able to make the world safer for these groups, and considerably velocity up the tempo of releasing land again to the communities residing with remnants of battle. The absolute best final result might be if sometime our companies are not wanted, as a result of explosive units are not scattered throughout fields and roads. Within the meantime, we’ll work every single day to place ourselves out of enterprise.
