3.1 computer vision system for the detection of drowning accidents
automated system including means for digitizing series of images of people in the pool basin (3.11),means for comparing and analysing digitized images and decision means for setting off and sending an alarm (3.5) to trained staff (3.7) when a detection (3.3) occurs
3.2 drowning
process of experiencing respiratory impairment from submersion/immersion in liquid
Note 1 to entry: Outcomes are classified as death, morbidity and no morbidity.
[SOURCE: World Health Organization]
3.3 detection
recognition of a total and prolonged immersion at the bottom of the pool basin (3.11) of a stationary solid mass such as a person or object
3.4 monitoring
active and constant observation of people in the pool basin (3.11) with the aim of preventing drowning (3.2) risks
3.5 alarm
notification by the computer vision system of a detection (3.3) to the identified trained staff (3.7)
4 Requirements
4.1 General
Computer vision systems are designed to complement lifeguards or trained staff and are not designed to reduce lifeguard supervision or staffing levels. The equipment and materials used shall be suitable for the environment in which their installation is intended (immersion depth, very high hygrometry, chemically aggressive atmosphere, etc.). Equipment and materials installed in a ≥60 % hygrometry environment shall be at least IP65 (degrees of protection provided by enclosures). Equipment and materials for use in a submerged environment shall be IP68 (see IEC 60529). For information, a typical rescue scenario is available in Annex A.
4.2 Technical study
Prior to any installation of a computer vision system for the detection of drowning accidents, a technical study shall be carried out by the supplier in consultation with or based on information provided by the swimming pool’s owner/operator. Depending on the computer vision system proposed, the technical study is used to quantify and to position the equipment making up the system, such as cameras, central processing unit, alarm tools and related equipment, in a document.
