Detailed Description

An embodiment of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the embodiment.

The embodiment provides a basketball teaching effect evaluation system, which is realized through basic necessary technical features so as to solve the problems provided by the technical background part in the application document.

Specifically, as shown in fig. 1, an embodiment of the present invention provides a basketball teaching effect evaluation system, including: the system comprises a personnel position acquisition module, a personnel distribution drawing module, a time formation evaluation module, a standard characteristic database, a time division module and an evaluation output module. The operation of each module will be described in detail below.

And the personnel position acquisition module is used for acquiring the position of each basketball player through a positioner worn on the body of the basketball player. The module uses a wearable device to secure the locator to the body of each basketball player and the location returned by the locator can be formatted as a coordinate, i.e., the location coordinates of each basketball player are collected at the module.

And the personnel distribution drawing module is used for establishing a blank picture, marking color values at corresponding positions on the blank picture according to the position of each basketball player at the current moment, and obtaining a personnel distribution map at the current moment. The module marks the coordinates on a blank picture in a color value mode according to the collected coordinates, each pixel does not have a color value when the blank picture is created, each pixel of the picture has a coordinate, the marked color values are changed on the pixels of the coordinates, and the marked picture is presented in an image mode, namely a personnel distribution diagram at the current moment. This step is performed at every moment.

And the time formation evaluation module is used for acquiring the evaluation characteristic value of the personnel distribution diagram at the current time, comparing the evaluation characteristic value with the standard characteristic value at the same time, and obtaining the difference value between the evaluation characteristic value and the standard characteristic value as a difference characteristic value. The module compares the evaluation characteristic value extracted from the staff distribution diagram with the standard characteristic value, and the characteristic value reflects the current queue condition of the staff, so that the difference is obtained by comparing the queue condition evaluated at the moment with the standard queue condition.

And the standard characteristic database is used for storing each time corresponding to the formation and a standard characteristic value corresponding to the current formation at each time. In the invention, each time corresponding to the formation and the standard characteristic value corresponding to the current formation at each time are stored in a list form, so that the searching and calling are more convenient.

And the time division module is used for executing the personnel distribution drawing module and the time formation evaluation module at each time respectively according to each time corresponding to the formation in the standard characteristic database, and traversing all the times corresponding to the formation to obtain a difference characteristic value corresponding to each time. The module execution module traverses the related modules according to the conditions at each moment so as to obtain all the difference characteristic values.

And the evaluation output module is used for calculating the weighted evaluation value of the difference characteristic value corresponding to each moment according to the weights corresponding to different moments and outputting the calculated result, wherein each moment uniquely corresponds to one weight. The module comprehensively outputs all the obtained difference characteristic values by weight, specifically, an adaptive weight is added to each difference characteristic value, and the weight is finally output, so that a numerical value is obtained at the moment, and the numerical value is the difference between the evaluation formation and the standard formation which reflect the whole body.

In the present invention, the time here is the time when the evaluation is started is defined as 0 time, and all times are time indexes with respect to 0 time, for example, 3 seconds is the 3 rd second from which the evaluation has been started.

In this embodiment, the standard feature database is further configured to store the formation names of the formation forms, and make the formation name of each formation form correspond to the standard feature value of the formation form at each time and each time in a one-to-one manner. Therefore, the standard feature database can be expanded, so that the standard feature database stores different corresponding standards, different team forms in different basketball team forms have different corresponding positions at different moments, the names of the team forms can use a storage area mode during storage, and in the storage area, the standard feature values corresponding to the team forms at all moments and the current team forms at all moments are stored in a list mode, so that the basketball team forms are more convenient to search and call.

Under the condition of expanding the standard characteristic database, the basketball teaching effect evaluation system provided by the invention, as shown in fig. 2, further comprises: the system comprises a formation selection module, a database screening module and a formation notification module. The operation of each module will be described in detail below.

And the formation selection module is used for receiving the formation name input by the judging personnel. The module can receive the formation name input by the judging personnel by using the input device, and can use input or selection input for inputting the formation name.

And the database screening module is used for screening all the moments corresponding to the formation names and the standard characteristic values corresponding to the formation names at all the moments in the standard characteristic database according to the input formation names, and suspending the calling of all the moments corresponding to the formation names and the standard characteristic values corresponding to the formation names at all the moments in the standard characteristic database by other formation names. The module provides calling support for the data which are in accordance with the regulation according to the recording condition, and does not provide calling support for the data which are not in accordance with the regulation. For example, the standard feature database stores data corresponding to formation a, data corresponding to formation B, data corresponding to formation C, and data corresponding to formation D, and the name of the formation entered by the judging person is formation C, at this time, the module makes the data corresponding to formation C support calling, and at the same time, the data corresponding to formation a, the data corresponding to formation B, and the data corresponding to formation D do not support calling.

And the formation notification module is used for broadcasting the formation name input by the formation selection module in a broadcasting display mode. Therefore, the team name input by the judge can be transmitted to the basketball team players in a broadcasting mode.

In this embodiment, the staff position obtaining module obtains the position of each basketball player simultaneously when obtaining the position of each basketball player. When the personnel distribution drawing module marks color values, according to different color values marked by different positions, each position uniquely corresponds to one color value.

Among the above-mentioned technical scheme, because the colour value that the difference of post corresponds is different, consequently, when basketball player post is confused, will make personnel's distribution diagram different, thereby make personnel's distribution diagram's eigenvalue different, that is to say the evaluation eigenvalue at this moment is different, and is like this, be the position promptly, also can not make evaluation eigenvalue unanimous with standard eigenvalue, thereby make when basketball evaluation, each basketball player's branch work is clear and definite, when basketball player post is confused, its final evaluation that obtains will reduce by a wide margin, thereby make the more accurate of evaluation.

In this embodiment, when the standard feature database is established, as shown in fig. 3, the method includes the following steps:

s1: and the distribution acquires the standard distribution diagram at each moment, and acquires the characteristic value of the standard distribution diagram at each moment as the standard characteristic value corresponding to the moment.

S2: and establishing each time corresponding to the formation in the standard characteristic database, and establishing a storage space of the standard characteristic value corresponding to each time.

S3: and sequentially recording the standard characteristic values obtained in the step S1 into the storage space according to the corresponding time.

The steps are a process of establishing a standard characteristic database, when the standard formation is established, the characteristic values of the personnel distribution diagrams at all the moments are obtained by respectively establishing the personnel distribution diagrams at all the moments, and the characteristic values are sequentially sequenced according to the corresponding moment sequences to obtain the characteristic values of the standards at all the moments, so that the standard characteristic values can be in one-to-one correspondence with the corresponding moments.

In this embodiment, the evaluation output module converts the calculation result into a percentage system and outputs the percentage system, so as to obtain a score. By means of the percentile system, basketball players and judgers can be more visual when watching the basketball players and the judgers.

Meanwhile, in this embodiment, the scores are broadcast in a display broadcast manner. This can make the effect of transmission better.

In the present invention, the display broadcasting mode refers to a mode of displaying through a display, a mode of broadcasting through voice, or a mode of combining the two modes.

The above disclosure is only for a few specific embodiments of the present invention, however, the present invention is not limited to the above embodiments, and any variations that can be made by those skilled in the art are intended to fall within the scope of the present invention.
