34、rding to the World Health Organization (WHO), is the process of experiencing respiratory impairment from submersion/immersion in liquid remains in public swimming pools with entrance fees. A certain number of studies211together demonstrate that for several reasons (physiological, cognitive, architec

35、tural, organizational, etc.), lifeguards may sometimes find themselves in difficulty when watching over swimmers, knowing that a potential risk of a drowning accident may occur.It is important to bear in mind that a lifeguard can supervise and inform swimmers to help ensure their safety as well as a

36、nticipate and intervene early to prevent an accident from occurring.Computer vision systems do not save people from drowning, as saving a drowning person necessarily requires human intervention.Installation and use of computer vision systems cannot serve as a reason to reduce human monitoring of swi

37、mming pools, unless a robust risk assessment does indicate this is possible without compromising safety, with reference to applicable national regulations, if any.In addition to the safety organization, these tools are solely for use by a competent person, who received prior training in the operatio

38、nal performances of these systems in accordance with the manufacturers and the swimming pool operators instructions.Not all possible drowning accidents can be detected by the systems described in this document, e.g. persons floating on or just below the water surface. Although the current state-of-t

39、he-art does not allow 100 % effectiveness, for several years, these technologies have proved their worth worldwide, by regularly helping lifeguards to identify potential drowning accidents that they had not observed.While it is possible to retrofit this type of equipment to an existing pool, conside

40、ration of its introduction is best at the pool design stage.In order to really enhance the drowning prevention in swimming pools, computer vision systems are designed to: scan continuously and with redundancy the pool basin; detect mathematically a solid mass, without trajectory, lying at the pool b

41、asin bottom; trigger electronically an alarm after the detection; limit false alarms by automatically differentiating a solid mass from light and shadow projections on the texture of the pool basin and by discriminating, without human intervention, a motionless solid mass above and below the water s

42、urface.A trained competent person cannot completely rely on such a system because: the system has limitations, which are covered in training for using the system; the systems performance can be compromised by various factors, which the trained competent person would be informed of automatically in r

43、eal time.Computer vision systems are foreseen to support the competent person in detecting drowning accidents at the pool basin bottom and reacting faster by saving precious seconds.The International Organization for Standardization (ISO) draws attention to the fact that it is claimed that complianc
