Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1-4, the present invention provides a treadmill-based stride monitoring method, comprising:
s1, acquiring the overall average stride of the user, the left foot average stride and the right foot average stride within a set time length;
s2, calculating a first difference value between the overall average stride and a recommended stride, wherein the recommended stride is obtained according to body data of a user and a preset rule;
s3, judging whether the first difference value exceeds a preset value;
s4, if the first difference exceeds the preset value, calculating the stride deviation percentage according to a formula, wherein the formula is that the difference between the left foot average stride and the right foot average stride is divided by the left foot average stride or the right foot average stride;
and S5, generating a stride adjustment guide according to the stride deviation percentage.
In step S1, the treadmill acquires the overall average stride length, the left foot average stride length, and the right foot average stride length of the user, acquires information such as the foot landing length, the corresponding stride length, and the stride frequency by using a visual recognition method, a sensor recognition method, and the like, and further acquires the overall average stride length, the left foot average stride length, and the right foot average stride length by calculating, wherein the set time is preset, for example, 60 seconds; the total average stride is the sum of all strides in the set time divided by the landing generation times; the average stride of the left foot is the sum of the strides generated by the landing of all the left feet in the set time divided by the landing generation times of the left feet, and the stride generated by the landing of the left foot is the stride generated by the front left foot and the rear right foot; similarly, the average stride of the right foot is the sum of the strides generated by the landing of all the right feet in the set time divided by the number of times of the landing of the right foot, and the stride generated by the landing of the right foot is the stride generated by the front right foot and the rear left foot; step frequency and speed can also be obtained, and the step rate, namely Npeak within 60 seconds, is calculated through the number of peaks per minute; the speed is calculated by a fixed formula, the speed equals step frequency equals step Npeak.
In step S2, the recommended stride is an ideal stride determined according to the actual height of the user, which may be input by the user or measured by the treadmill, for example, the recommended stride is 0.45 times the height of the user.
In the above step S3, in some embodiments, the preset value is 0, the exceeding of the preset value includes being greater than the preset value and being less than the preset value, and the first difference being less than 0 represents that the stride is small, for example, the stride may be increased appropriately due to the decrease of the exercise efficiency; the first difference value is larger than 0, which represents that the stride is large, the risk of sports injury exists, adjustment can be suggested, and the stride is properly reduced; in some embodiments, the preset value may be a range value.
In step S4, the stride length deviation percentage can be used to determine the user' S stride length deviation, and further determine whether adjustment is needed.
In some embodiments, stride deviation percentages for the left foot and the right foot may be calculated, respectively, where the stride deviation percentage for the left foot is the difference between the average stride for the left foot and the recommended stride divided by the average stride for the left foot; the stride deviation percentage of the right foot is the difference between the average stride of the right foot and the recommended stride divided by the average stride of the right foot, so that the stride deviation of the left foot and the stride of the right foot can be judged, and the stride of the foot with larger deviation can be independently and reasonably adjusted.
In step S5, the larger the absolute value of the stride deviation percentage is, the larger the deviation of the stride is, therefore, several intervals may be designed for the absolute value of the stride deviation percentage, and different stride adjustment guides may be generated according to the different intervals, and the stride adjustment guides may include the prompt information and the stride guide to obtain the position of the adjusted landing point.
In conclusion, the technical problem that the conventional running machine cannot correct the abnormal stride of the user is solved.
Further, the step S1 of obtaining the user' S overall average stride and the left and right average strides over a set length of time includes:
s11, acquiring the current amplitude and the foot movement visual information of the user in the movement process of the user;
s12, identifying each current amplitude change as one-time grounding when reaching the peak;
s13, identifying a grounding foot corresponding to each grounding and a stride corresponding to the grounding foot when each grounding by the foot motion visual information, wherein the grounding foot is the front one of the left foot and the right foot;
s14, calculating to obtain the overall average stride of the user, the average stride of the left foot and the average stride of the right foot within the set time length according to the number of times of landing recognized within the set time length and the corresponding stride; when the stride condition of the user is obtained, the participation of a sensor is not needed, and the technical problem that the stride monitoring result is unstable when the existing running machine monitors the stride through the sensor is solved.
In the step S11, the current amplitude of the brushless motor in the treadmill is read by software, so as to obtain the change of the current amplitude; the foot movement visual information in the camera module in the treadmill is acquired through software, and the camera module is arranged in front of the conveyor belt and can directly shoot the foot movement condition of a user and the movement condition of the conveyor belt; in some embodiments, the software may be provided in a treadmill, and in some embodiments, the software is provided in a mobile terminal, for example, a wearable device such as a mobile phone of a user, a smart watch, and the like, and the cooperation between the mobile terminal and the treadmill is realized through data interaction.
In the above step S12, since the current amplitude changes substantially periodically during the running process of the user on the treadmill, the current amplitude suddenly increases when the user has his or her foot down to ensure the normal movement of the conveyor belt, and usually the current amplitude changes most sharply when the user has his or her foot down to step on the conveyor belt, and the current amplitude gradually decreases before both feet step on the conveyor belt to the following foot lifting and stepping on the conveyor belt, it can be accurately identified whether there is a foot landing by the peaks of the current amplitude change, each peak representing the landing of one foot, that is, the foot landing on the conveyor belt.
In the step S13, the user can visually recognize which foot is stepping on the conveyor belt from the foot motion visual information, and calculate the distance between the two feet, i.e., the stride length, by combining the reference size; therefore, the current amplitude reaches the peak due to the fact that the foot steps on the conveyor belt can be judged, one-time landing is achieved, and the corresponding stride is obtained; the step length corresponding to the landing foot refers to the step length measured when the landing foot falls on the ground, for example, the left foot is the landing foot, and then the step length measured when the left foot falls on the ground is the step length corresponding to the landing foot.
In step S14, the recognized number of times of landing and the corresponding step length are the recognized steps measured each time of landing and each time of landing, and the set time is preset, for example, 60 seconds; the total average stride is the sum of all strides in the set time divided by the landing generation times; the average stride of the left foot is the sum of the strides generated by the landing of all the left feet in the set time divided by the landing generation times of the left feet; similarly, the average stride of the right foot is the sum of the strides generated by the landing of all the right feet in the set time divided by the number of times of landing of the right feet; step frequency and speed can also be obtained, and the step rate, namely Npeak within 60 seconds, is calculated through the number of peaks per minute; the speed is calculated by a fixed formula, the speed equals step frequency equals step Npeak.
Further, the step S12 of identifying each current amplitude variation as one landing when the amplitude reaches the peak includes:
s121, calculating the gradient of the current amplitude change;
and S122, when the gradient reaches the set value, determining the gradient as a peak and identifying the gradient as one-time landing.
In the step S121, the user may step on the conveyor belt according to the gradient of the current amplitude change.
In step S122, the setting value can be adjusted according to the different hardware structure of the treadmill.
Further, the step S13 of identifying the landing foot corresponding to each landing from the foot motion visual information and identifying the stride corresponding to the landing foot at each landing includes:
s131, determining the foot margin according to the foot motion visual information;
s132, acquiring the number of standard interval marks between the previous landing position and the current landing position on the conveyor belt when the ground feet land according to the foot movement visual information;
and S33, obtaining the distance between the previous landing position and the current landing position on the conveyor belt at each landing according to the conversion of the standard interval mark and the actual unit, wherein the distance is the stride corresponding to the landing foot.
In the above-mentioned steps S31-S33, the left foot and the right foot can be distinguished by the external shape of the foot based on the visual recognition, and whether the left foot or the right foot lands can be judged by the image recognition algorithm; the standard interval marks can be special-shaped patterns, such as squares, each pattern represents a standard length in the moving direction of the conveyor belt, for example, the length of each standard interval mark is 5cm, the actual unit of each standard interval mark is 5cm, a plurality of standard patterns are sequentially connected to form a reference scale, the reference scale can be arranged on the fixed frames at two sides of the conveyor belt or on the conveyor belt, and two adjacent patterns are staggered in the transverse direction perpendicular to the moving direction of the conveyor belt, so that the patterns are convenient to identify; the stride is obtained by multiplying the number of standard interval marks between the previous landing position and the current landing position on the conveyor belt by the actual unit of 5 cm.
Further, before the step S5 of obtaining the first difference between the overall average stride and the recommended stride, the method includes:
s10, obtaining the height of the user;
and S20, calculating the recommended stride according to the height of the user, wherein the recommended stride is 0.45 times of the height of the user.
In the above steps S10-S20, the user may use the treadmill to input the height, or the height of the user using the terminal, wherein the formula is a calculation formula recommended for sports science, and the user' S body can be better protected according to the recommended stride exercise, so as to avoid the injury of the user.
Further, in some embodiments, the step S5 of generating the stride adjustment guideline according to the stride deviation percentage includes:
s51, comparing the absolute value of the stride deviation percentage with a preset interval end value, and judging the interval in which the absolute value of the stride deviation percentage is positioned, wherein the number of the intervals is three, and the end values of the intervals are a first interval, a second interval and a third interval from small to large in sequence;
s52, when the absolute value of the stride deviation percentage is in the first interval, generating display information of the stride;
s53, when the absolute value of the stride deviation percentage is in a second interval, generating first early warning information and generating a correction prompt, wherein the correction prompt is used for indicating the recommended landing position;
and S54, when the absolute value of the stride deviation percentage is in a third interval, generating second early warning information, and stopping running the treadmill.
In the above steps S51-S54, in this embodiment, the first interval is within 5%, the second interval is 5% -10%, and the third interval is greater than 10%; when the absolute value of the stride deviation percentage is in the first interval, the stride is represented to be relatively balanced and in a safe range, the stride does not need to be corrected, and only the display information of the stride is generated and transmitted to a user; when the absolute value of the stride deviation percentage is in a second interval, representing that the running action of the user is asymmetric and has a certain deviation, early warning and adjustment are suggested, wherein the first early warning information comprises a reminding content of the user, and the user is reminded to correct according to a correction prompt; when the absolute value of the stride deviation percentage is in the third interval, the running action of the user is represented to be large and asymmetric, a certain movement damage risk exists, the early warning suggestion carries out special correction training, the running machine stops running, and the situation that the user continuously moves to cause larger movement damage is avoided.
Further, in some embodiments, the step of generating the corrective prompt includes:
s531, judging whether an empty foot appears based on visual identification and/or current amplitude change;
s532, acquiring the position of the floor foot corresponding to the soaring foot;
s533, determining a recommended landing position of the flight foot according to the position of the foot margin and the recommended stride;
and S534, displaying the recommended landing position of the flight in a display screen of the treadmill.
In step S531, whether an empty foot occurs may be determined by visual recognition alone, may be determined by current amplitude change alone, and may be determined by visual recognition and current amplitude change at the same time; the soaring foot refers to a foot which is in a soaring state and is about to fall at a front position; whether the current amplitude of the soar foot is judged to be the current amplitude of the brushless motor for driving the running belt in the user movement process or not based on the current amplitude change, generally, time is taken as a horizontal axis, the current magnitude is taken as a vertical axis, and whether the soar foot is caused by the fact that the soar foot is lifted or not is judged according to the change rule of the current when the foot is lifted.

In the step S534, the landing position and the position of the landed foot are displayed on the display screen, and the landing position is changed according to the position change of the landed foot, so that the user can conveniently adjust the stride according to the landing position displayed on the screen.
