Expanding upon the ongoing dialogue about utilizing drones for mine detection, questions have emerged regarding the practicality of employing thermal imaging. In this thread, I will discuss this matter by referencing a specialized manual dedicated to this topic.🧵Thread:

2/ To begin, it's essential to consider a few key aspects. Mines aren't always placed on a top of soil - some remain hidden, making them invisible to drones. This distinction is important, emphasizing the need to refrain from regarding this method as panacea

3/ The parameters for this presentation are outlined as follows:

Temperature: Range of +18 to +20°C (64.4 to 68°F)
Vegetation: Moderate level
Time: 21:00 (9 PM) local time
Altitude: Varied and indicated for each scenario in the image.
Drone: DJI Mavic 3T
Deployment time: 11 AM

4/ In this specific instance, both mine #1 (ТМ-62 М) and mine #2 (ТМ-62П3) are clearly visible when positioned atop the soil. They exhibit a noticeable contrast in terms of shape and color compared to their surroundings.

5/ In this scenario, AP mine #3 (MOН-100) stands out significantly and can be readily identified, whereas the smaller AP mines — mine #4 (ПМН-2) and mine #5 (МС-3) — are diminished visually, even at an altitude of 50 meters, and look the same.

6/ Mines that are remotely deployed, such as mine #6 (ПОМ-3), can also be detected effectively. In this specific instance, the distinct shape of the mine is clearly apparent to the drone operator. The altitude in this case ranges from 16 to 25 meters.

7/ Mine detection is also achievable based on features that deviate from natural object forms. Nevertheless, it's noteworthy that this necessitates the operator to possess experience and/or training in order to discern less conspicuous objects.

8/ It should be emphasized that mines with non-metallic enclosures had cooled by the time of testing, in contrast to metallic ones that retained warmth. Notably, both types of mines remained discernible due to distinct temperature signatures relative to the environment.
