德国铁路公司计划于近期在各铁路站点区域试飞配备了红外相机的无人机，用以监控各区内公物在夜间被涂鸦或损毁的情况，并收集相关证据以便对破坏者进行处罚。不过，德国相当严苛的反监控法或对此类无人机的使用产生影响。德国铁路发言人表示，无人机上只会在夜间在车厢上涂鸦现象比较集中的大型站点上空飞行，红外相机也只关注铁路公司旗下的产业，铁路站点以外的人和物不在拍摄范围内。据悉，德国铁路公司每年用于清理各类涂鸦的花费高达760万欧元（约合100万美元），而每架无人机的成本约为6万欧元，可在距离地面150米的上空近乎无声飞行。 Germany's national railway company, Deutsche Bahn, plans to test small drones to try to reduce the amount of graffiti being sprayed on its property. The idea is to use airborne infra-red cameras to collect evidence, which could then be used to prosecute vandals who deface property at night. A company spokesman said drones would be tested at rail depots soon. But it is not yet clear how Germany's strict anti-surveillance laws might affect their use. Graffiti is reported to cost Deutsche Bahn about 7.6m euros ($10m) a year. German media report that each drone will cost about 60,000 euros and fly almost silently, up to 150m (495ft) above ground. Using cameras to film people surreptitiously is a sensitive issue in Germany, where privacy is very highly valued. |
