Pool Watch
【B1】______The Royal Society for the Prevention of Accidents says that on average 15 people drown in British pools each year, but many more suffer major injury after getting into difficulties. Now a French company has developed an artificial intelligence system called Poseidon that sounds the alarm when it sees someone in danger of drowning.
When a swimmer sinks towards the bottom of the pool, the new system sends an alarm signal to a poolside monitoring station and a lifeguard’s pagerd(携带式电子呼叫机). In trials at a pool in Ancenis, it saved a life within just a few months, says Alistair McQuade, a spokesman for its maker, Poseidon Technologies.
【B2】______AI software analyses the images to work out swimmers’ trajectories(轨迹). To do this reliably , it has to tell the difference between a swimmer and the shadow of someone being cast onto the bottom or side of the pool. "The underwater environment is a very dynamic one, with many shadows and reflections dancing around, "says McQuade.
The software does this by "projecting" a shape in its field of view onto an image of the far wall of the pool. It does the same with an image from another camera viewing the shape from a different angle. If the two projections are in the same position, the shape is identified as a shadow and is ignored.【B3】______
To pick out potential drowning victims, anyone in the water who starts to descend slowly is added to the software’s "pre-alert" list, says McQuade.【B4】______Poseidon double-checks that the image really is of a swimmer, not a shadow, by seeing whether it obscures the pool’ s floor texture when viewed from overhead. If so, it alerts the lifeguard, showing the swimmer’ s location on a poolside screen.
The first full-scale Poseidon system will be officially opened next week at a pool in High Wycombe, Buckinghamshire.【B5】______Baylis runs a company that installs swimming pools—and he was once an underwater escapologist(擅长从捆扎的绳索中脱身的杂技演员)with a circus. "I say full marks to them if this works and can save lives, " he says.
A. But if they are different, the shape is a swimmer and so the system follows its trajectory.
B. One man who is impressed with the idea is Travor Baylis, inventor of the clockwork(时钟机构)radio.
C. Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble.
D. Baylis says that any local authority spending £30, 000—plus on a Poseidon system ought to be investing similar amounts in teaching children to swim.
E. Swimmers who then stay immobile on the pool bottom for 5 seconds or more are considered in danger of drowning.
F. Poseidon keeps watch through a network of underwater and overhead video cameras.

选项
答案
A
解析
这段话讲的是波塞冬系统对投射在游泳池里的影像进行分析的原理。由前面两句话“它对一个从不同角度看到这个形状的摄像机上的图像做了同样的处理。如果这两个投影在同一位置,这个形状就被认作是阴影而被忽略掉。”可知,此处应该是从另一种角度来看这个形状。A项符合语境。
