Pool Watch

Swimmers can drown in busy swimming pools when lifeguards fail to notice that they are in trouble.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 pool-
side monitoring station and a lifeguard's pager."In trials at a pool in Ancenis,near Nantes,it saved a life
within just a few months,"says Alistair McQuade,a spokesman for its maker,Poseidon Technologies.
Poseidon keeps watch through a network of underwater and overheard video cameras.Al software analy-
ses the images to work out swimmers trajectories（轨道，轨线）.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 under-
water 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.But if they are
different.the shape is a swimmer and so the system follows its trajectory.
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.Swimmers who then stay immobile on the pool bottom for 5
seconds or more are considered in danger of drowning.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.One man who is impressed with the idea is Travor Baylis,inventor of the clockwork ra-
dio.Baylis runs a company that installs swimming pools一and he was once an underwater escapologist（表演
脱身术的人）with a circus. " I say full marks to them if this works and can save lives , " he says. But h"
adds that any local authority spending ￡30,000一plus a on Poseidon system ought to be investing similar
amounts in teaching children to swim. What is required of Al software to save a life?
A.It must be able to swim.
B.It must keep walking round the pool.
C.It can distinguish between a swimmer and a shadow.
D.It can save a life within a few months.
