27、ion) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be r
28、epresented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to d
29、evelop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the
30、ISO/IEC Directives, Part 2 (see www.iso.org/directives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights.

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
44、e with this document may involve the use of patents concerning computer vision technologies for the detection of drowning accidents in swimming pools, given in 3.1.ISO takes no position concerning the evidence, validity and scope of these patent rights.The holder of these patent rights has assured I
