Early on a June morning in 2023, my colleagues and I drove down a bumpy dust highway north of Kyiv in Ukraine. The Ukrainian Armed Forces had been conducting coaching workout routines close by, and mortar shells arced by way of the sky. We arrived at an enormous area for a know-how demonstration arrange by the United Nations. Throughout the 25-hectare area—that’s in regards to the measurement of 62 American soccer fields—the U.N. staff had scattered 50 to 100 inert mines and different ordnance. Our activity was to fly our drone over the world 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 dimensions was daunting: The world was 10 instances 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 activity, and it got here away with greater than 15,000 photos. Then we raced again to the lodge with the info it had collected and commenced an all-night coding session.
We had been completely satisfied to see that our customized machine studying mannequin took solely about 2 hours to crunch by way of all of the visible information and determine potential mines and ordnance. However establishing a map for the complete space that included the particular coordinates of all of the detected mines in below 72 hours was merely not attainable with any affordable computational sources. 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 areas the place suspected land mines had 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 had been in Ukraine, we additionally demonstrated our know-how for the
State Particular Transportation Service, a department of the Ukrainian navy accountable for protecting roads and bridges open.
All our onerous work paid off. At this time, our know-how 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 individuals. Our aim is to make our know-how 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 struggle linger lengthy after conflicts have died down. At this time, an estimated 60 international locations are nonetheless contaminated by mines and unexploded ordnance, in accordance with the
2023 Landmine Monitor report. These risks embody land mines, improvised explosive units, and shells and artillery that didn’t explode on touchdown—all collectively, they’re referred to as explosive ordnance (EO). Greater than 4,700 individuals had been killed or wounded by EO in 2022, in accordance with the Landmine Monitor report, and the overwhelming majority of these casualties had been civilians. At this time, Ukraine is essentially the most contaminated place on the earth. A few third of its land—an space the dimensions of Florida—is estimated to comprise EO.
In humanitarian mine-clearing work, the standard course of for releasing EO-contaminated land again to the neighborhood hasn’t modified a lot over the previous 50 years. First a nontechnical survey is performed the place personnel exit to speak with native individuals about which areas are suspected of being contaminated. Subsequent comes the technical survey, wherein personnel use metallic detectors, educated canine, mechanical demining machines, and geophysical strategies to determine all of the hazards inside a mined space. This course of is gradual, dangerous, and vulnerable 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 staff of explosive-ordnance-disposal specialists both disarm or destroy the explosives.

Most deminers would agree that it’s not very best to determine the EO as they stroll by way of the contaminated space; it will be significantly 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, they usually can shortly 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 professional to research a drone picture and test for EO. At that fee, it will take greater than 500 million person-hours to manually search imagery protecting 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 a large endeavor, however it’s inside purpose.
“At this time, our know-how is being utilized by a number of humanitarian nonprofits detecting land mines in Ukraine.”
Humanitarian demining teams are gradual 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 elimination are starting to combine drones into their normal procedures. In addition to accumulating aerial imagery of huge 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 schooling, in 2020 I cofounded the corporate now referred to as Secure Professional AI to push the know-how 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 very important.
How We Obtained Began With Drones for Demining
In Ukraine in March 2024, the creator [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 determine explosives [bottom].

I grew to become all for land-mine detection whereas learning geological science as an undergraduate at Binghamton College, New York. By means of my work within the Geophysics and Distant Sensing Laboratory run by Timothy de Smet and Alex Nikulin, I bought concerned in a undertaking to detect the PFM-1, a Russian-made antipersonnel land mine often known as the butterfly mine attributable to its distinctive form and since it’s sometimes scattered by plane or artillery shells. Afghanistan continues to be contaminated with many of those mines, left behind greater than 40 years in the past after the Soviet-Afghan Conflict. They’re notably problematic as a result of they’re largely fabricated from plastic, with just a few small metallic elements; to search out them with a metallic detector requires turning up the tools’s sensitivity, which results in extra false positives.
In 2019, we educated a machine studying mannequin by scattering inert PFM-1 land mines and accumulating visible imagery through drone flights in numerous environments, together with roads, city areas, grassy fields, and locations with taller vegetation. Our ensuing mannequin accurately detected 92 p.c of PFM-1s in these environments, on common. Whereas we had been happy with its efficiency, the mannequin may determine solely that one sort of land mine, and provided that they had been above floor. Nonetheless, this work supplied the proof of idea that paved the best way for what we’re doing at the moment. In 2020, Steinberg and I based the Demining Analysis Group, a nonprofit whose aim is to advance the sector of humanitarian mine elimination 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 information for a lot of various kinds of explosives: small antipersonnel mines, bigger antitank mines, improvised explosive units, grenades, and plenty of different harmful explosive belongings you by no means need to encounter.
Our Software program Resolution for Demining by Drone
To develop our know-how for real-world use, Steinberg and I cofounded Secure Professional AI and joined Secure Professional Group, an organization that gives drone providers and sells protecting gear for demining crews. Going into this work, we had been conscious of many tutorial proposals for brand spanking 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 in regards to the issues they face and the options they’d prefer to see. In mild of these conversations, we developed a user-friendly Net software referred to as SpotlightAI. Any approved individual can go surfing to the web site and add their imagery from a industrial off-the-shelf drone; our system will then run the visible information 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 know-how will substitute human labor—personnel will nonetheless need to undergo fields with metallic detectors to make certain the drones haven’t missed something. However the drones can pace 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 huge check of our know-how 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 advised me through satellite tv for pc cellphone 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 know-how in a real-world minefield surroundings after which for the 2023 U.N. demonstration beforehand described. In one other journey this previous March, we visited minefields in jap Ukraine which are at present being demined by nonprofit organizations utilizing our SpotlightAI system. We had 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 struggle nonetheless hinder reconstruction. Many individuals flee, however the ones who keep are confronted with tough choices. They have to steadiness important actions resembling farming and rebuilding with the dangers posed by pursing these actions in areas that may have land mines and explosive ordnance. Seeing the demining operations firsthand bolstered the affect of the work, and listening to the demining operators’ suggestions within the area helped us additional refine the know-how.
We’ve continued to enhance the efficiency of our mannequin, and it has lastly reached a degree the place it’s virtually nearly as good as an professional human in detecting EO on the floor from visible imagery, whereas performing this activity many instances quicker than any human may. Generally it even finds objects which are closely obscured by vegetation. To provide it superhuman capabilities to see below the dust, we have to usher in different detection modalities. For instance, whereas we initially rejected thermal imaging as a stand-alone detection technique, we’re now experimenting with utilizing it along with visible imaging. The visual–imagery-based machine studying mannequin returns the detection outcomes, however we then add a thermal overlay that may reveal different info—for instance, it would present a floor disturbance that means a buried object.
The largest problem we’re grappling with now could be easy methods 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 top and protection. An algorithm then converts these estimates right into a warmth map exhibiting how seemingly it’s that the machine studying mannequin can detect EO in every space: For instance, it would present a 95 p.c detection fee in a flat space with low grass, and solely a 5 p.c detection fee in a area with bushes and bushes. Whereas this strategy doesn’t resolve the issue posed by vegetation, it offers deminers extra context for our outcomes. We’re additionally incorporating extra vegetation imagery into our coaching information itself to enhance the mannequin’s detection fee in such conditions.
In the summertime of 2022, the creator and Gabriel Steinberg spent two weeks testing their applied sciences at an explosives vary in Oklahoma.

SMITH ROBINSON MULTIMEDIA
To supply these providers in a scalable method, Secure Professional AI has partnered with Amazon Net Companies, which is offering computational sources 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 median drone pilot can acquire 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 dimensions 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 satisfy the wants of deminers in Ukraine.
What’s Subsequent for Our Humanitarian Demining Work
One apparent method we may enhance our know-how 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 and find buried objects.
We discovered that lidar is beneficial for detecting trenches which are indicative of floor disturbance, however it will possibly’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 encircling soil, however we sometimes see a robust differential solely in sure environments and at sure instances of day. Magnetometers are the perfect instruments for detecting buried metallic targets—they’re essentially the most just 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 fee. 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 might need to navigate by way of bushes or different terrain obstacles. We’re persevering with to experiment with these modalities to develop an clever sensor-fusion technique to detect as many targets as attainable.
Proper now, SpotlightAI can detect and determine greater than 150 kinds of EO, and it’s additionally fairly good at generalization—if it encounters a kind of land mine it by no means noticed in its coaching information, it’s prone to determine it as one thing worthy of consideration. It’s aware of virtually all American and Russian munitions, in addition to some Israeli and Italian varieties, and we will 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 international locations are nonetheless coping with contamination. Perhaps we’ll ultimately have separate fashions for locations resembling Angola, Iraq, and Laos.
Our hope is that within the subsequent few years, our know-how will change into a part of the usual process for demining groups—we would like each staff to have a drone that maps out floor contamination earlier than anybody units foot right into a minefield. We hope we will make the world safer for these groups, and considerably pace up the tempo of releasing land again to the communities residing with remnants of struggle. The very best final result will likely be if sometime our providers are now not wanted, as a result of explosive units are now not scattered throughout fields and roads. Within the meantime, we’ll work every single day to place ourselves out of enterprise.
