Embodiment Construction

[0019] Pattern recognition is to study the automatic processing and interpretation of patterns by computer using mathematical techniques. We refer to environments and objects collectively as "patterns". With the development of computer technology, it is possible for humans to study complex information processing processes. An important form of information processing is the identification of living organisms to the environment and objects. Of particular importance to humans is the recognition of optical information (obtained through the organs of vision) and acoustic information (obtained through the organs of hearing). These are two important aspects of pattern recognition.

[0020] Indoor positioning refers to the realization of position positioning in the indoor environment. It mainly adopts wireless communication, base station positioning, inertial navigation positioning and other technologies to form an indoor position positioning system, so as to realize the position mo...

Abstract

The invention relates to a drowning prevention identification method based on a mode identification and fingerprint matching and positioning algorithm. The method is used for recuing simmers when the simmers are drowning, and comprises the following steps: S1, building a fingerprint database; S2, obtaining motion video of the swimmers by cameras which are arranged around the swimmers; S3, analyzing the motion video of the simmers and judging whether the swimmers are drowning or not, positioning the swimmers if the swimmers are drowning, analyzing the subsequently-obtained motion video of the swimmers if the swimmers are not drowning; S4, determining the positions of the swimmers by using a fingerprint matching and positioning algorithm through wifi modules which are worn by the swimmers and a fingerprint database.

Description

technical field [0001] The invention relates to an anti-drowning identification method based on a pattern identification and fingerprint matching positioning algorithm. Background technique [0002] Swimming is one of the sports that men, women and children alike like. Swimming can develop muscles symmetrically and enhance cold resistance. During swimming, due to the stimulation of water temperature, the body needs to maintain sufficient temperature. Skin blood vessels are involved in an important regulatory role, and the stimulation of cold water can make skin blood vessels constrict to prevent heat from spreading outside the body. At the same time, the body is stepping up to generate heat to expand the blood vessels of the skin and improve the blood supply to the blood vessels of the skin. Such long-term exercise can strengthen the blood circulation of the skin, promote metabolism and cultivate a brave and tenacious will. Swimming is a fun recreational activity only if ...
