Furthermore, the teaching module is connected with a stroke calibration module which is mainly used for calibrating the personal standard action stroke of the exerciser and assisting to form a corresponding action standard curve to be output to the display device. More specifically, the stroke calibration module is used for shooting the first position data when the counterweight is stretched to the maximum from the initial position by the exerciser in a correct posture and the second position data when the counterweight is retracted to the minimum from the correct posture from the exerciser in the actual state data obtained by the data processing module in the process of one-time reciprocating motion of the counterweight used by the exerciser through the optical shooting module.

In practice, the calibration process may be repeated for three or more rounds to more accurately calculate the individual standard motion profile of the exerciser.
In this embodiment, the teaching module forms a motion standard curve of the counterweight used by the exerciser according to the value interval determined by the minimum pre-estimated position value and the maximum pre-estimated position value and the motion period given by the electronic motion guidance content, and outputs the motion standard curve to the display device, so that the exerciser can conveniently perform self-service stretching motion monitoring according to the motion standard curve through a visual means, and the whole process of counterweight training can be completed as far as possible according to the motion standard curve.
To further illustrate that the real-time interactive system of the present embodiment can adjust the improper actions of the exerciser and correctly guide the exerciser to complete the weight training through the action standard curve, the following specific examples are provided:
referring to the visual interface on the display device, the exemplary training of the recommender is illustrated as shown in fig. 2.
Firstly, calibrating the standard action travel of the exerciser: the standard action strokes of the body-building people are different due to different physiques, and the process is completed by combining an optical shooting module, a data processing module, a stroke calibration module and a teaching module. For example, prior to the training of the recommender: firstly, shooting an image of a counterweight identification mark when an arm and an elbow of a body builder form a 90-degree included angle through an optical shooting module, acquiring actual state data of the counterweight at the moment through a data processing module, acquiring first position data through a stroke calibration module, and finally extracting a maximum estimated position value through a teaching module; shooting an image of a counterweight identification mark when the exerciser pushes up and keeps the elbow joint slightly bent through an optical shooting module, acquiring actual state data of the counterweight at the moment through a data processing module, acquiring second position data through a stroke calibration module, and finally extracting a minimum estimated position value through a teaching module. For the calibration process, three or more rounds can be further executed to process and obtain a more accurate standard action travel. The standard motion profile is a range of motion amplitudes that are customized based on the individual fitness of the exerciser. As shown in fig. 2, when the display device visually presents the action standard curve, the sine wave shape curve is formed by using the standard action stroke (the numerical range defined by the maximum estimated position value and the minimum estimated position value) as the amplitude value.
Then, when the action standard curve is outputted to the interface of the display device, for interest, a sinusoidal waveform curve formed by arranging a plurality of discontinuous symbolic points (such as strawberries and grapes) is formed by further multimedia processing as shown in fig. 2, but the form of the curve is not limited thereto. In the figure, the grape at the bottom represents the minimum predicted position value, the grape at the top represents the maximum predicted position value, and the strawberry represents the position value of the path between the maximum predicted position value and the minimum predicted position value. The time of the action standard curve from the peak position to the next adjacent peak position represents an action cycle, and the action cycle is given by the electronic motion guidance content. According to an action period given by the electronic motion guidance content, the continuous multiple symbolic points respectively correspond to estimated state data continuously generated by the teaching module in the period according to the time sequence, and specifically comprise time coordinates and estimated data such as the motion direction and position coordinates of the identification mark of the counterweight. When training is actually carried out, the number of movements is also determined in the electronic movement guidance content, and the action standard curve repeatedly presents an action cycle. The symbolic points are used for providing more visual human-computer interaction experience for the body builder in the process of weight training, so that the evaluation module is clear in comparison between the actual motion state and the established standard state of the body builder, and further the self-service body building experience is improved.
Then, the bird in the interface represents the actual state data of the counterweight used by the exerciser, specifically comprises the actual identification movement direction, position coordinates and other data of the counterweight, and is visually presented to the exerciser by the position feedback signal. In order to realize automatic statistics of exercise data of a body builder and enhance man-machine interactivity, exercise data statistics modules such as 'balance weight', 'times', 'group number', 'calorie', 'integral' and the like are further arranged on the interface, so that the body builder can know the exercise data related to the training process in real time, and meanwhile, the exercise data are transmitted to the cloud end in a supporting mode, the cloud end is enabled to specifically analyze the exercise trend and the exercise effect of the body builder and feed back, the electronic exercise guidance content is updated accordingly, the exercise of the body builder is ensured to be gradual, and scientific body building is realized. As shown in fig. 2, the strawberry score representing the general path is low and the grape score representing the maximum/minimum predicted position value is high, and particularly under the guidance of the action standard curve (in a manner of moving transversely on the visual interface based on a given action cycle), the exerciser controls the birds to move up and down to eat as much strawberry and grape as possible. If the action standard of the body builder is basically consistent with the curve in action speed and action amplitude, the evaluation module outputs an evaluation signal that strawberry or grape is eaten by the bird and an integral is obtained in real time, so that the body building enthusiasm of the body builder can be stimulated; if the body builder does not act in a standard way, and the action speed or the action amplitude is greatly inconsistent with the curve, the evaluation module outputs an evaluation signal that the strawberry or the grape is not eaten by the bird and cannot be integrated or is integrated less in real time, so that the user can adjust the improper action and strive for the best training effect.
In the embodiment, in order to identify the identity information of different fitness users and call the corresponding exercise data, on the basis of the embodiment, the display device is connected with an identity identification module; more specifically, the identity recognition module is used for acquiring identity information of the body builder, recognizing and confirming whether the body builder conforms to the pre-stored identity information, and calling relevant motion data of the body builder through the cloud after confirming that the identity information of the body builder conforms to the pre-stored identity information, wherein the relevant motion data comprises a pre-stored maximum pre-estimated position value and a pre-stored minimum pre-estimated position value. Furthermore, the cloud stores electronic motion guidance contents related to the body builder in advance, and sends the electronic motion guidance contents corresponding to the identity information and the related motion data to the teaching module after confirming that the identity information of the body builder is consistent.
The invention also provides a real-time interaction method for realizing the real-time interaction system, which comprises the following steps:
