醫師國考加油! 高二上 (2021/03/14): Thousands of miles away, drones are being enlisted in the fight against crime. In several U.K. cities, police agencies are employing drones in place of far more expensive manned helicopters. Though the drones are not very large, they are capable of carrying cameras and devices that detect body heat. A policeman can operate one of these drones using a remote control. By wearing special glasses, he or she can see exactly what the drone sees as it flies. In one incident, (B)a policeman used a drone to follow a suspected car thief. Even after the suspect disappeared in thick fog, the officer was able to track him with the drone and guide fellow policemen to his location. Police agencies have found more uses for drones, such as border protection and maritime security. | 檢舉 |
