具体实施方式detailed description
下面结合实施例参照附图进行详细说明，以便对本发明的技术特征及优点进行更深入的诠释。The following will describe in detail with reference to the accompanying drawings in conjunction with the embodiments, so as to further explain the technical features and advantages of the present invention.
实施例1Example 1
本发明的方法流程图如图1所示，一种基于智能手环判断篮球动作的方法，包括如下步骤。The flow chart of the method of the present invention is shown in Figure 1, a method for judging a basketball action based on a smart bracelet, including the following steps.
本发明的步骤S1为：设置篮球动作对应的传感器捕获的加速度值区间及智能手环的振动幅度，每一篮球动作对应一加速度值区间及振动幅度。作为本发明的较佳实施例，本发明步骤S1所述篮球动作包括跳起、投篮、突破、抢断及篮板。智能手环的振动幅度通过三轴陀螺仪传感器获取每个方向的加速度及移动的距离，通过篮球相对于手左右移动的距离来获得振动幅度。Step S1 of the present invention is: setting the acceleration value interval captured by the sensor corresponding to the basketball action and the vibration amplitude of the smart bracelet, and each basketball action corresponds to an acceleration value interval and vibration amplitude. As a preferred embodiment of the present invention, the basketball actions described in step S1 of the present invention include jumping, shooting, breakthrough, stealing and rebounding. The vibration amplitude of the smart bracelet obtains the acceleration in each direction and the moving distance through the three-axis gyroscope sensor, and obtains the vibration amplitude through the distance that the basketball moves left and right relative to the hand.
在本发明中，S1所述的捕获的加速度值区间及智能手环的振动幅度通过在智能手环内置传感器实现。特别是所述传感器为三轴陀螺仪传感器。但本发明并不限于三轴陀螺仪传感器，任何能够实现检测篮球动作向上加速度和向前加速度及振动幅度的传感器均可，例如重力加速度等。三轴陀螺仪传感器能同时测定6个方向的位置、移动轨迹、加速。 单轴的只能测量两个方向的量，也就是一个系统需要三个陀螺仪，而3轴的一个就能替代三个单轴的。因此，为了能更好的检测用户篮球动作，优先选择三轴陀螺仪传感器。In the present invention, the captured acceleration value interval described in S1 and the vibration amplitude of the smart bracelet are realized by a built-in sensor in the smart bracelet. In particular the sensor is a three-axis gyro sensor. However, the present invention is not limited to the three-axis gyroscope sensor, any sensor capable of detecting the upward acceleration, forward acceleration and vibration amplitude of the basketball movement, such as the acceleration of gravity, etc. can be used. The three-axis gyro sensor can simultaneously measure the position, movement trajectory, and acceleration in six directions. The single-axis can only measure the quantity in two directions, that is, a system needs three gyroscopes, and one of the three axes can replace three single-axis. Therefore, in order to better detect the user's basketball action, the three-axis gyro sensor is preferred.
S1所述设置篮球动作对应的传感器捕获的加速度值区间及智能手环的振动幅度包括： The acceleration range captured by the sensor corresponding to the basketball action described in S1 and the vibration amplitude of the smart bracelet include:
设置向上运动的加速度a1，向前运动加速度为a2，振动幅度为A。Set the upward movement acceleration a1, the forward movement acceleration a2, and the vibration amplitude as A.
跳起动作：当向上运动的加速度a1的值为m≦a1﹤M，判定为跳起动作；用户在运动时，佩戴智能手环，当开启智能手环后，三轴陀螺仪传感器开始实时获取用户的运动加速度，包括3个方向的加速度，当然为了便于计算，本发明只是取两个方向的加速度，例如向上运动的加速度a1，向前运动的加速度a2。并根据获取的结果进行计算。当向上运动的加速度a1的值在m≦a1﹤M这个区间时，则判定为用户此时有跳起动作。m、M为大于零的值，由系统设置或用户根据需要设定。Jumping action: when the value of the acceleration a1 of upward movement is m≦a1﹤M, it is judged as a jumping action; when the user is exercising, wear a smart bracelet, and when the smart bracelet is turned on, the three-axis gyroscope sensor starts to acquire data in real time The user's motion acceleration includes the acceleration in three directions. Of course, for the convenience of calculation, the present invention only takes the acceleration in two directions, such as the acceleration a1 of upward movement and the acceleration a2 of forward movement. and perform calculations based on the obtained results. When the value of the upward motion acceleration a1 is in the interval m≦a1<M, it is determined that the user has a jumping action at this time. m and M are values greater than zero, which are set by the system or by the user as required.
投篮动作：当向上运动的加速度a1的值为n≦a1，且向前运动的加速度a2的值为N≦a2时，判定为投篮动作；因为投篮动作一般为向前向上动作，所以对这两个方向的运动加速度进行捕捉和判定。在本发明中，设定为当向上运动的加速度a1的值为n≦a1，且向前运动的加速度a2的值为N≦a2时，判定为投篮动作。这样当向上运动的加速度a1与向前运动的加速度a2超过预设值，且两个条件都满足时，即判定为投篮动作。如果只是满足了一个条件，则不能判定为投篮动作，两个条件必须同时满足。n、N为大于零的值，由系统设置或用户根据需要设定。Shooting action: When the value of acceleration a1 of upward movement is n≦a1, and the value of acceleration a2 of forward movement is N≦a2, it is judged as a shooting action; because shooting action is generally forward and upward, so the two The motion acceleration in one direction is captured and judged. In the present invention, it is set that when the value of the upward motion acceleration a1 is n≦a1, and the value of the forward motion acceleration a2 is N≦a2, it is determined to be a shooting action. In this way, when the acceleration a1 of the upward movement and the acceleration a2 of the forward movement exceed the preset values and both conditions are met, it is determined to be a shooting action. If only one condition is met, it cannot be judged as a shooting action, and both conditions must be met at the same time. n and N are values greater than zero, which are set by the system or by the user as required.
突破动作：当向前运动的加速度a2的值为j≦a2时，判定为带球突破；用户在运动中，如果带球突破，必然具备一定的向前运动的加速度，如果速度太慢则无法完成突破，所以在本发明中，设定当向前运动的加速度a2的值为j≦a2时，判定为带球突破动作。如果向前运动加速度太慢，则不能判定为突破动作。j为大于零的值，由系统设置或用户根据需要设定。Breakthrough action: When the value of the forward acceleration a2 is j≦a2, it is determined to be a breakthrough with the ball; if the user is in motion, if the user breaks through with the ball, he must have a certain forward acceleration. If the speed is too slow, he cannot The breakthrough is completed, so in the present invention, when the value of the forward acceleration a2 is j≦a2, it is determined to be a breakthrough with the ball. If the acceleration of the forward movement is too slow, it cannot be judged as a breakthrough movement. j is a value greater than zero, which is set by the system or by the user according to needs.
抢断动作：当向上运动的加速度a1的值为a1﹤n、向前运动的加速度a2的值为a2﹤N满足条件之一，且振动幅度A的值为i≦A时，判定为抢断动作；在用户运动中，抢断动作必然带来手部的剧烈振动，当然智能手环能感应到该振动，并捕获该振动幅度。但在抢断动作中，仅仅有抢断动作，而不满足投篮动作。例如，用户运动中，振动幅度A的值为i≦A时，且能满足向上运动的加速度a1的值为a1﹤n和向前运动的加速度a2的值为a2﹤N两个条件之一或两个都满足时，则判定为抢断动作。i为大于零的值，由系统设置或用户根据需要设定。Stealing action: when the value of acceleration a1 of upward movement is a1<n, the value of acceleration a2 of forward movement is a2<N, and one of the conditions is satisfied, and the value of vibration amplitude A is i≦A, it is determined to be a stealing action; During the user's movement, the stealing action will inevitably bring about severe vibration of the hand. Of course, the smart bracelet can sense the vibration and capture the vibration amplitude. But in the stealing action, there is only the stealing action, and the shooting action is not satisfied. For example, during the user’s movement, when the value of the vibration amplitude A is i≦A, and the value of the acceleration a1 for upward movement is a1<n and the value of acceleration a2 for forward movement is a2<N, one of the two conditions can be satisfied or When both are satisfied, it is judged as a stealing action. i is a value greater than zero, which is set by the system or by the user as required.
篮板动作：当向上运动的加速度a1的值为K≦a1，且振动幅度A的值为k≦A时，判定为篮板动作；用户运动中，篮板动作一般具有一定的加速度，且振动幅度比较大，所以为篮板动作设定一个向上运动加速度阀值K及一个振动幅度阀值k，当向上运动的加速度a1达到阀值K，且振动幅度A达到阀值k，则判定为篮板动作。k、K为大于零的值，由系统设置或用户根据需要设定。Rebound action: When the value of acceleration a1 of upward movement is K≦a1, and the value of vibration amplitude A is k≦A, it is determined to be a rebound action; during user movement, rebound action generally has a certain acceleration and the vibration amplitude is relatively large , so an upward motion acceleration threshold K and a vibration amplitude threshold k are set for the rebound action. When the upward motion acceleration a1 reaches the threshold K and the vibration amplitude A reaches the threshold k, it is judged as a rebound action. k and K are values greater than zero, which are set by the system or by the user according to needs.
本发明的步骤S2为：实时捕获智能手环的实时加速度值及振动幅度；用户在运动时，佩戴智能手环，当开启智能手环后，三轴陀螺仪传感器开始实时获取用户的运动加速度，包括3个方向的加速度，当然为了便于计算，本发明只是取两个方向的加速度，例如向上运动的加速度a1，向前运动的加速度a2，同时捕获手部振动幅度A，根据获取的结果进行计算。得出向上运动的加速度a1向前运动的加速度a2、手部振动幅度A的值。Step S2 of the present invention is: capture the real-time acceleration value and vibration amplitude of the smart bracelet in real time; the user wears the smart bracelet when exercising, and when the smart bracelet is turned on, the three-axis gyroscope sensor starts to acquire the user's motion acceleration in real time, Including the acceleration in three directions, of course, for the convenience of calculation, the present invention only takes the acceleration in two directions, such as the acceleration a1 of upward movement, the acceleration a2 of forward movement, and captures the hand vibration amplitude A at the same time, and calculates according to the obtained results . The acceleration a1 of upward movement, the acceleration a2 of forward movement and the value of hand vibration amplitude A are obtained.
本发明的步骤S3为：根据实时加速度值及振动幅度判定篮球动作。步骤S2获得的向上运动的加速度a1向前运动的加速度a2、手部振动幅度A的值与步骤S1中预设置进行对比，如果落入某个动作的区间值，则判定为该动作，否则视为无效动作。The step S3 of the present invention is: judging the basketball action according to the real-time acceleration value and the vibration amplitude. The acceleration a1 of upward movement obtained in step S2, the acceleration a2 of forward movement, and the value of hand vibration amplitude A are compared with the preset values in step S1. is an invalid action.
