Description

Child running posture correction training system

Technical field

The invention relates to the field of computer aided technology, and relates to a motion posture correction training system, in particular to a running posture correction training system which is inaccurate for a child running posture.

Background technique

Exercise can not only strengthen the body, expand personal interests, but also develop the body's motor coordination, promote the development of the body's musculoskeletal, and the development of the mind. The development of children's motor coordination ability runs through the development of children's motor ability. It is not only restricted by children's neurodevelopmental maturity, but also plays an important role in promoting the development of children's nerves, muscles and bones, and can promote children's language, intelligence and emotions. The development of abilities, so parents pay great attention to the interest in cultivating children's sports, but pay less attention to the correctness of children's sports postures and the rules that are suitable for children's own sports. In addition, not everyone can ask a full-time coach for training, or a transfer coach may not be able to grasp the correct posture for each child, and the correct posture will not only reduce sports injuries, but also improve personal movement. The potential to play the potential of individual sports. Running is a kind of exercise that can be used without any restrictions on the venue. The correct running posture not only can play a good exercise, but also reduce sports injuries. In real life, not only can children not master the correct running posture, but most adults do not know what is the correct running posture. Therefore, mastering the correct running posture, especially in children, can grasp the correct running posture, which is very important for children's growth.

In the prior art, various related studies have been conducted on this. For example, CN104052518A, the applicant is Shenzhen Qiwo Zhilian Technology Co., Ltd., the invention patent application with the name of the wearable watch with the track and motion measurement and management functions, discloses a watch with the track and motion measurement and management functions. The utility model mainly comprises a watch body, comprising a box body for mounting the body related device, and a belt body connecting the box body, wherein the two ends of the belt body have connected devices, and an action posture sensor is used for obtaining the orientation of the user. And posture, a GPS locator for locating the position of the user of the wearable device, using the GPS data processing unit and the action gesture computing unit to understand the whereabouts and actions of the wearer, a data transmission and display block connecting the GPS processing unit, the action The posture arithmetic unit and the audiovisual block convey the measured information to a necessary position and display it at the request of the user. It can be seen that the wearing device can measure the child's exercise posture. And positioning, and issuing warning information according to the child's posture abnormality, but the device does not correct and train the child's exercise posture.

CN104687653A, the applicant is Guangdong Xiaotiancai Technology Co., Ltd., and the invention patent application for the method, device, bracelet and system for promoting child movement discloses a device and method for supervising children's exercise, which mainly includes wearable The device obtains the child growth index, compares the child growth index with the child standard index, obtains the comparison result, and publishes the exercise task according to the result, and detects the action information through the action sensor in the wearable device to determine the completion of the released exercise task, if the task is completed And a short-range communication device in the wearable device is activated, and the preset control command is sent to the terminal bound to the wearable device by the short-range communication device to implement control of the smart terminal by the wearable device. If the comparison result is greater than the set threshold, the child is not qualified, and the corresponding exercise task is issued according to the child growth non-conformity index. If the comparison result is less than the preset threshold and the child growth qualified index is obtained, the balanced development exercise task is released. It can be seen that the motion promotion method merely motivates children to participate in sports by combining the use of electronic products with the movement of children, especially electronic entertainment projects such as video games, but the invention It does not involve correcting the child's exercise posture, and cannot solve the problem of correcting the inaccurate posture of the child.

CN105303183A, the applicant is Nanjing University of Posts and Telecommunications, and the invention title is a invention patent of a wearable device-based child gesture recognition analysis system and method, and discloses a wearable device capable of analyzing a child's posture, mainly including first collecting the wearer's Basic motion data, analyze the data, extract the characteristics of the wearer's different basic motion poses, and set the feature area, then monitor the wearer's real-time motion pose in real time, perform feature area matching on the pose data, and finally match the matching results. The processing uses the probability of matching success to determine the current wearer's motion posture and steady state. If the motion matching is stable and stable, continue to monitor. If the matching is unstable, when the unstable state exceeds the set stable threshold, The communication module is called to issue a reminder alarm. When the matching probability is lower than the alarm threshold, the security exception alarm is issued. It can be seen that the main purpose of the invention is to identify and analyze the child's movement posture, thereby alarming and protecting the child's movement abnormality, but the invention still does not have the problem of correcting and training the child's motion posture irregularity.
