According to US media reports, on October 15, a young boy named Essen and a pet dog were lost near the town of Pamo, Minnesota, USA. A total of 600 volunteers participated in the search and rescue, and the local police also dispatched patrol helicopters. Searching, many people who are concerned about the event prayed for the boy online.

The search and rescue work continued from 4 pm to late night. Due to the lack of additional lighting on the farm night, the visibility was extremely poor and the outdoor temperature dropped drastically, which brought great difficulties to the search and rescue work. I thought that Steve, a volunteer from the drone service company, brought his drone, a multi-functional drone developed by an industrial drone manufacturer（http://www.mmcuav.com/） in China, equipped with a thermal imaging lens. It can continue to work at night.

It is understood that the thermal imaging camera used by Steve integrates a high-precision thermal imaging sensor and a 4K visible light sensor. It can record and transmit thermal imaging and visible light effects at the same time. In real-time image transmission, thermal imaging and visible image can be displayed side by side or picture-in-picture according to the needs. At the same time, the latest machine intelligence technology is combined with FLIR MSX image enhancement technology. The combination of visible light and thermal imaging provides rich detail and produces sharper thermal imaging, making it easier for users to identify targets. At two o'clock in the morning, when searching for a cornfield about a mile from the farm, two spots appeared in the thermal image, and a long spot was moving in place. "I think it should be a pet dog." And the boy, so I informed everyone," Steve said. Search and rescue personnel immediately went to the location to successfully find Ethan and his pet dog.

After being rescued, the boy had all the good signs and had returned home after being examined by the hospital.
