Description
Technical Field
The invention relates to the technical field of computers, in particular to a swimming tracking method, a swimming tracking device, a swimming tracking storage medium and terminal equipment.
Background
Swimming sports are one of the favorite sports items of people. The swimming pool can develop muscles regularly, strengthen cold resistance and improve physical quality. During swimming, the body is kept at a sufficient temperature due to the stimulation of the water temperature. The skin blood vessels participate in important regulation, and the stimulation of cold water can shrink the skin blood vessels to prevent heat from diffusing to the outside of the body. At the same time, the body is tightened to generate heat, so that the skin blood vessel is expanded, and the blood supply to the skin blood vessel is improved. Thus, the long-term swimming exercise can strengthen the blood circulation of the skin, promote metabolism, cultivate the spiritual intension of brave and tenacious, and the like.
However, swimming is an interesting recreational sport only if swimming safety is ensured. Estimated by the World Health Organization (WHO), about 38 million people die globally each year from unintentional drowning, with the majority of global drowning deaths occurring in children under the age of 15. Drowning is the "first killer" of an accident in children, exceeding 50% of the accidental deaths in this age group. Drowning accidents not only cause huge losses to the nation and the society, but also cause heavy attacks to families. It is also statistical that professional lifeguards at the swimming pool can only detect up to 70% of drowning events within 30-40 seconds of the occurrence of the drowning event, and over time they will gradually find the rest of the drowning people, but also reduce the possibility of saving these lives.
In order to improve the rescue efficiency of the lifeguard, the survival probability of drowning people is increased, and the occurrence of drowning accidents is avoided. The conventional scheme is generally as follows: an alarm module, such as a bracelet, is configured for each swimmer, and when the swimmer drowns, the swimmer can alarm through the bracelet.
However, the above solution requires an alarm module for each swimmer, and the hardware configuration is too costly. And need artificially control the bracelet to report to the police moreover, under the condition that the swimmer was drowned, the swimmer probably does not control the bracelet and reports to the police because of reasons such as frightening, especially young children. In addition, the swimmer may discard the alarm module during swimming, and the monitoring alarm system cannot know whether the swimmer drowns, so that the safety performance is not high.

Detailed Description
In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.
Referring to fig. 1, an embodiment of the present invention provides an application environment for tracking swimming drowning. The application environment can be arranged in the environment of indoor or outdoor swimming pools and swimming fields. The application environment at least comprises a central monitoring platform, a camera arranged in a swimming area and an information receiving device worn by a lifesaver. The camera is in communication connection with the central monitoring platform, and the central monitoring platform is in communication connection with the information receiving device. The central monitoring platform may include a processor for receiving images or video captured by the camera. The central monitoring platform can process according to the received images or videos so as to determine whether drowning alarm is performed or not. When the central monitoring platform determines to alarm, the alarm information can be sent to an information receiving device worn by a rescuer. The alarm information may include information such as a swimming location of a swimmer who has drowned and an image or video recording the latest swimming situation of the swimmer. The information receiving device may include a headset, a display (or a projection device), and the like. Of course, the central monitoring platform can also perform drowning alarm in other forms, for example, the drowning condition is broadcast through a loudspeaker or the drowning condition is displayed through a display, and the like.
Referring to fig. 2, an embodiment of the present invention provides a method for tracking swimming, which can be applied to swimming monitoring of indoor or outdoor swimming pools and swimming fields. The system for monitoring the swimming condition at least comprises a central monitoring platform, a camera arranged in the swimming area and a lifesaving person wearing the central monitoring platform. The embodiment includes steps S100 to S400, which are specifically as follows:
s100, images of swimmers entering a swimming area are acquired.
The swimming area can include a monitoring area that can be shot by a camera, an area entering a swimming pool, an area entering a preset range from the side of the swimming pool, and the like, and can be set according to specific conditions. The acquired image of the swimmer comprises at least the face of the swimmer. Of course, the torso of the swimmer may also be included.
In some embodiments, a video of a captured swimmer entering a swimming area may be acquired, and then a clearer frame image may be extracted from the acquired video.
S200, judging whether the swimmer meets the tracking condition or not according to the acquired image of the swimmer entering the swimming area.
In some embodiments, tracking conditions may include lack of swimming skills, pre-set monitoring objects, and the like. The monitoring target may be set in advance as a certain person or a group of a certain category. For example: children, teenagers, etc.
In some embodiments, a face recognition algorithm, i.e., a recognition model, may be used to recognize the face of the swimmer recorded in the image of the swimmer, so as to determine whether the swimmer is the set monitoring object. The face recognition algorithm can be generated by training a neural network through sample face data in advance. The sample face data includes a sample face image and identifies whether a face of the sample face image is a monitoring object. Training the neural network model through a large amount of sample face data until the network converges. The network convergence refers to inputting a sample face image into a face recognition algorithm, and the obtained output result is consistent with the identifier corresponding to the sample face image.
Illustratively, the juvenile may be the subject of monitoring because of its small age, relatively weak swimming skills and relatively immature mental intelligence, which is prone to panic when encountering a risk of drowning.
In some embodiments, if the acquired image of the swimmer further includes the swimmer's body, after the identity to which the face of the image belongs is recognized through the face recognition algorithm, the swimmer's body may be further compared with the bodies of other swimmers of the swimming area to determine whether the swimmer's body is a young swimmer. Therefore, the accuracy of swimmer identity recognition can be improved. The comparison factors involved in the comparison process may include height, head size, thickness of the limbs, etc. For example, if the height of the swimmer is shorter than the heights of most other swimmers of the same sex, for example, the height of the swimmer is only up to a position below the waist of most other swimmers, the swimmer is considered to be a young swimmer.
And S300, if the swimmer meets the tracking condition, tracking the swimming condition of the swimmer.
In some embodiments, taking the monitoring object as a young person, if the young person leaves the swimming area, the swimming condition of the swimmer is not tracked any more. If the young swimmer enters the deep water area from the shallow water area, a lifesaver of the swimming area is notified, and the lifesaver can further monitor the swimming condition of the young swimmer. If desired, the rescuer can prevent the young swimmer from entering the deep water area from the shallow water area.
In some embodiments, in the case that the number of cameras set in the swimming area is limited, a swimming video of the whole swimming area may be captured, an image of the face of the swimmer to be tracked may be captured, the swimming video of the swimmer may be captured from the swimming video, and the swimming condition of the swimmer may be determined according to the captured swimming video.
S400, if the swimming condition of the swimmer meets the drowning standard, the swimming position of the swimmer is obtained to give a drowning alarm.
In some embodiments, the swimmer can judge whether the swimmer meets the drowning standard through the information of the swimmer's limb movement, facial expression, and the water bloom generated during swimming. Drowning criteria may be considered met if one or more of the following swimming conditions exist, as follows: the limb movement is changed too much from the limb movement of the normal swimming, the facial expression is panic or is converted into a dull state from panic, the water consumption is too much and is continuously generated in one area, and the like.
Drowning alarms may include, but are not limited to, alarms to a lifesaver, family members where drowning occurs, or other security personnel. The drowning condition can be broadcast through a loudspeaker or displayed through a display.
In some embodiments, at the time of alarming, information such as a swimming location of a swimmer who drowned and an image or video recording the latest swimming condition of the swimmer may be transmitted to the lifeguard. If the swimming area is divided into a plurality of areas, and each lifesaver is responsible for monitoring the area where the lifesaver is located, the sending of information to the lifesaver may include: the swimmer who drowned is a lifeguard in the area or adjacent area where the swimmer is swimming. The lifeguards in other areas continue to monitor the swimming conditions of the areas where the lifeguards are located, so that the swimming monitoring of other swimmers is avoided being neglected in the rescue process.
The embodiment can identify a young swimmer through the image and then track the swimming condition of the young swimmer so as to avoid the occurrence of a drowning event of a child.
In some embodiments, tracking of swimming conditions for a swimmer entering the swimming area is also required if the swimmer is not swimming or is not good at swimming, i.e., is not provided with swimming skills. As shown in fig. 3, the method provided in this embodiment includes steps S510 to S530 as follows:
s510, an initial swimming video of the swimmer is obtained.
The initial swim video may include a video that records the initial period of time that the swimmer entered into the swimming pool to swim.
And S520, judging whether the swimmer has swimming skills or not according to the initial swimming video.
In some embodiments, it is compared whether the swimming stroke of the swimmer is in compliance with the standard swimming stroke based on the initial swimming video of the swimmer. The standard swimming posture comprises free swimming, backstroke, breaststroke, butterfly swimming, side swimming, diving and the like. In particular, an initial swim video of a swimmer may be compared to a swim video corresponding to a standard swim gesture. If the difference between the two motions is large, the swimmer is considered to be not provided with swimming skills. For example, the action of the swimmer is determined to be breaststroke through video comparison, and if the leg action of the swimmer during the swimming process does not meet the leg action of the standard breaststroke, the swimmer is considered to have no swimming skill. If it is not possible to determine which specific swimming style the swimmer's action is by video matching, it can be assumed that the swimmer does not have swimming skills.
S530, if the swimmer does not have swimming skill, judging that the swimmer meets the tracking condition. At this time, the swimming situation of the swimmer can be tracked.
In this embodiment, the tracking manner for tracking a swimmer without swim skills may be the same as the tracking manner for tracking a younger.
In some embodiments, if the swimmer leaves the swimming area, the swimmer's swimming conditions are no longer tracked. If a swimmer without swim skills enters a deep water area from a shallow water area, a lifeguard of the swim area is notified, and the lifeguard can further monitor the swimming condition of the swimmer without swim skills. If desired, the rescuer can prevent the swimmer from entering from a shallow water area to a deep water area.
In some embodiments, as shown in fig. 4, the tracking process for tracking the swimming condition of the swimmer provided by the present embodiment may include steps S310 to S350, as follows:
s310, acquiring a video for tracking the swimming condition of the swimmer in a preset time period. For example, the time period may be half a minute, one minute, or the like.
Taking the time period as one minute as an example, the process of acquiring the video may be as follows: the start tracking time of the video tracking the swim situation of the swimmer is 10: 00, then from time 10: 00 begins with acquiring a video tracking the swimmer's swimming situation every minute during that minute. If the current time is 10: 05, the acquired video comprises 10: 00 to 10: video of 01, 10: 01 to 10: 02, 10: 02 to 10: 03 and 10: 04 to 10: 05.
And S320, comparing the body motion of the video swimmer in the current time period with the historically acquired body motion of the video swimmer in other time periods.
And S330, judging whether the swimmer has drowning risk according to the change situation.
As an example, if the current time is 10: 05, then the video in the current time period is 10: 04 to 10: 05. Thus, 10: 04 to 10: 05 with the last few videos historically captured, e.g., 10: 00 to 10: video of 01, 10: 01 to 10: 02 video and 10: 02 to 10: 03, comparison was performed.
If the comparison result shows that the swimming postures belong to the same swimming posture, 10: 04 to 10: 05, the limb actions in the videos and the limb actions in the latest videos which are acquired in history and belong to one swimming gesture are changed too much, so that the risk of drowning can be considered, and whether the drowning is caused needs to be determined by combining other conditions. Illustratively, if the leg action in the video in the current time period is different from the leg actions of several videos which are most recent in history, for example, the leg has the situations of stopping action, too small action amplitude, stiff action and the like, the drowning risk such as excessive leg fatigue, leg cramp and the like can be considered.
If the comparison result shows that the swimming postures are different from the swimming postures recorded by the historical video and belong to one swimming posture, the swimmer can be considered to have a drowning risk when trying to perform a new swimming posture.
S330, if the swimmer has drowning risk, acquiring the facial expression and water bloom change condition of the swimmer in the video in the current time period.
And S340, determining the swimming condition of the swimmer according to the obtained facial expression and the water bloom change condition.
In some embodiments, the video image may be recognized using facial expression recognition algorithms to determine the facial expression of the swimmer in the video, such as: calm, smile, fright, red and whitish. The water bloom change condition comprises the frequency of water bloom occurrence, the height change of water bloom, the change of water bloom occurrence area and the like. The facial expression recognition algorithm may be generated by pre-training in a training manner similar to the aforementioned facial recognition algorithm.
And if the facial expression of the swimmer is determined to be drowning expression such as frightening, red swelling, white hair and the like, the occurrence frequency of the splash is too high, the height of the splash is high, and the splash occurrence area is in the same area, the swimmer is considered to meet the drowning standard.
In some embodiments, the process of alerting the lifesaver of the swimming area in the above step S400 may include: acquiring a latest image tracking the swimming condition of the swimmer; and sending the swimming location and the latest image of the swimmer's location to a rescuer of the swimming area to alert the rescuer.
The latest images can be extracted from a plurality of images or videos recording the latest swimming condition of the swimmer, so that the lifeguard can conveniently confirm the condition and the surrounding environment of the drowned swimmer. The lifeguard may be provided with glasses in which a projection device is provided to project the acquired image onto the glasses. The rescuer can see the projected image from the glasses.
In some embodiments, at least two infrared emitters may be provided in the swimming area, and the infrared emitters may be provided in different places so that the emitted infrared rays may intersect. The rescuer may be provided with specific glasses through which the rescuer can see the infrared rays emitting the infrared emitter.
Therefore, after the swimming position of the drowned swimmer is obtained, the infrared emitter for controlling the swimming area emits at least two infrared rays, so that the intersection point of the infrared rays is positioned at the swimming position of the swimmer. Thus, the lifeguard can quickly determine the swimming position of the drowned swimmer so as to quickly perform rescue.
In some embodiments, the swimmer may wear an alarm device, such as a bracelet. The swimmer can send drowning alarm request through the bracelet under the condition of drowning. As shown in fig. 5, the present embodiment also provides a method for tracking swimming when a swimmer is drowning alarming, comprising steps S610 to S640, as follows:
s610, receiving a drowning alarm request of the swimmer. Wherein the drowning warning request may be sent by a warning device worn by the swimmer. The drowning warning request may include information such as the swim location of the swimmer.
And S620, positioning the swimmer according to the swimming position and shooting the swimmer.
And S630, judging whether the swimming condition of the swimmer meets the drowning standard or not according to the shot image of the swimmer.
And S640, if the swimming condition of the swimmer meets the drowning standard, alarming to a lifeguard in the swimming area.
The embodiment can avoid the situation that the alarm is directly executed when the swimmer mistakenly operates to send a drowning alarm request to the monitoring system, can position the swimmer to determine whether the swimming situation is true or not, and then alarms the lifesaver, thereby avoiding the waste of alarm resources.
