The discrimination system 10 is basically used with a spin bike provided for spinning, and may be separately installed on the front and/or side of the spin bike or integrally implemented with the spin bike.

The storage unit 100 stores at least one piece of spinning content to assist in spinning training performed through a spin bike. For example, the spinning content may consist of background music and images of a trainer exercising in line with the background music captured from the front and side of the spin bike.

Such spinning content may be classified in various ways according to trainer instructors, background music, level of difficulty, and the like, and background music and images may be output together through the display unit 200 according to the exerciser's selection.

On the other hand, in spinning contents, the trainer's posture, movement pattern, and pedaling speed can be used as a reference for evaluating the exerciser's performance.

To this end, the reference generator 300 divides the video included in the spinning content into a plurality of sections, and analyzes the trainer's posture, movement pattern, and pedaling speed in each section to generate motion references for each section. .

2 is a block diagram showing the detailed configuration of a reference generator according to an embodiment of the present invention, and FIG. 3 is a diagram showing various examples of movement patterns in an operation section according to an embodiment of the present invention.

Referring to FIG. 2 , the reference generator 300 may include a video segment division unit 310, a motion reference generator 320, a posture reference generator 330, and a speed reference generator 340.

The video section divider 310 may divide the spinning content video into a plurality of sections. At this time, the divided video section can be largely divided into a preparation section and an action section. Here, the preparation section refers to a section in which the spinning instructor only pedals without any choreography or explains the next action, and the action section may mean a section in which choreography is performed through upper body movement along with pedaling.

In addition, the motion section may be further divided into several pattern sections according to movement patterns of the trainer's head, hands, hips, and the like.

Specifically, the image section divider 310 detects the movement line by tracking the movement of the head in the spinning image, patterns the detected movement line as shown in (a) to (f) of FIG. 2, and repeats the same pattern. By labeling and classifying the sections, the operation section can be subdivided. For example, (a) of FIG. 2 is the first pattern section, (b) is the second pattern section, (c) is the third pattern section, (d) is the fourth pattern section, and (e) is the second pattern section. As a 5-pattern section, (f) can be divided into a 6th pattern section, respectively.

The motion reference generating unit 320 may generate motion references by using feature values of motions of the trainer in each motion section. For example, the positions, displacements, and velocities of the head and hands in the movement patterns of the trainer appearing in each pattern section may be calculated, and motion references for each section may be generated based on the calculated values.

On the other hand, in order to prevent injury to exercisers and maximize exercise effects in spinning training, motions according to head and hand movements, that is, references to the posture and speed of pedaling a spin bike are required in addition to performance.

Accordingly, the posture reference generating unit 330 calculates average values of the trainer's handle grip position, spine and waist angle, hip position, elbow and knee positions and angles, etc. in each video section, and based on the average values, the posture for each section is calculated. A reference can be created.

In addition, the speed reference generating unit 310 may calculate the pedaling speed using the height displacement value of the pedals of the spin bike or the trainer's feet or knees in each video section, and based on this, may generate a speed reference for each section. there is.

Motion, posture, and speed references generated in each video section may be stored in the storage unit 100, and the reference generator 300 describes the motion of the trainer in each section using the divided video section and reference information. It may further include a motion guide generation unit 350 that generates a motion guide containing the motion guide.

The generated motion guide is stored together with a reference for each section, and may appear through the display unit 200 in a video section before the corresponding video section is output. Accordingly, the exerciser can prepare by predicting the trainer's motion, that is, posture, movement pattern, pedaling speed, etc., in the next video section by looking at the motion guide.

The measurement unit 400 is a device for detecting and measuring the motion of a spinning exerciser, and may be implemented with a camera module capable of photographing the exerciser from the front and/or side of the spin bike, various motion sensors, or wearable sensors. For example, the measuring unit 400 is a motion sensor, and may be implemented as position and displacements sensors, proximity sensors, speed sensors, torque sensors, and the like. In addition, the measuring unit 400 is a device for measuring the pedaling speed of an exerciser, and may include a sensor module mounted on a disk or pedal of a spin bike to directly measure the rotational speed.

In particular, the measurement unit 400 detects the positions of body parts such as the head, hands, knees, shoulders, elbows, waist, and ankles of the exerciser during spinning training, and the moving direction, moving distance, and moving speed according to their movements. etc. can be measured, and the measured motion information can be provided to the determining unit 500 .

The determination unit 500 may compare the motion of the spinning exerciser with the motion of the trainer on the spinning content to determine fitness of the exerciser's motion.

4 is a block diagram showing a detailed configuration of a determination unit according to an embodiment of the present invention.

Referring to FIG. 4 , the determination unit 500 may include a posture comparison determination unit 510 , a motion comparison determination unit 520 and a speed comparison determination unit 530 .

The motion suitability determination is performed by comparing the trainer's posture, motion, and speed reference generated in the reference generator 300 and stored in the storage unit 100 with the measured exerciser's motion information in units of each video section to determine the degree of similarity. It can be done.

The posture comparison determining unit 510 is a component for evaluating a basic posture when an exerciser performs pedaling in a preparation section and an action section. The motion information for determining the posture may include the position of the handle grip, the angles of the spine and waist, the positions and angles of the elbows, knees, and ankles, the position of the hips, and the like.

Specifically, the posture comparison determining unit 510 is a posture determining element, which part of the handle grip is held by the exerciser, whether the upper body leans forward at an appropriate angle, whether the waist is not backward, and whether the position or angle of the elbow is appropriate. Whether pedaling is performed with the knee widened or completely straightened, whether the ankle is maintained in 'L' position during pedaling, and whether the hip is in a balanced position can be compared and determined by referring to the posture preference.

The motion comparison and determination unit 520 is a component for evaluating whether or not movements of the exerciser's head, hands, etc. are appropriately performed along with the movements of the trainer in the motion section. That is, in each pattern section constituting the motion section, the trainer uses his head and hands to form a certain pattern and shows movement, and it is determined how similarly the exerciser followed it.

Specifically, the motion comparison and determination unit 530 analyzes the measured values of the position, displacement, and speed of the exerciser's head and hands, and compares them with the motion reference in consideration of the shape, range, and timing of the motion pattern. .

The speed comparison determining unit 530 is a component for evaluating whether an appropriate pedaling motion is maintained according to the beat of the background music or the speed required by the trainer in the video section. The pedaling speed may be calculated using a value obtained by measuring the number of rotations of a disk or pedal from a sensor module mounted on a spin bike, and the calculated value may be compared with a speed reference to compare and determine the pedaling speed of the exerciser.

As described above, the result of comparing and judging the motion of the exerciser and the motion of the trainer in the determination unit 500 may be provided to the feedback unit 600, and the feedback unit 600 provides a sense of exercise efficiency and achievement of the exerciser based on the result of the comparison and determination. It can enhance and further provide various feedback to prevent injury.

5 is a block diagram showing a detailed configuration of a feedback unit according to an embodiment of the present invention.

Referring to FIG. 5 , the feedback unit 600 may include a posture correction unit 610 and a fitness calculator 620 .

The posture correction unit 610 displays an infographic or illustration for correction along with a message while the spinning exercise is in progress so that the exerciser can correct the wrong posture based on the result of the determination of the posture comparison determiner 510 ( 200), and a report on matters requiring improvement can be provided even after the spinning exercise is over.

For example, the posture correction unit 610 may output an infographic and a message (eg, “Hold the grip number 2”) guiding the correct hand position when the position of the exerciser's handle grip is incorrect, and the hip falls backward. If the waist angle is out of tolerance compared to the reference, an illustration and message showing the correct waist angle (e.g., “Please tuck your back in”) can be output.

The fitness calculation unit 620 provides a basic score that evaluates whether the spinning posture is correctly maintained in the entire video section, a performance score that evaluates how well you followed the motion of the upper body in each motion section by comparing it with the trainer, and a request in each video section. Muscular strength scores for evaluating whether pedaling has been performed continuously at a tempo that is desired are calculated, respectively, and the exerciser's motion fitness for the corresponding spinning content can be calculated by summing them.

In the above, the present invention has been described with reference to the embodiments shown in the drawings, but this is only exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. will be.
