The recognition methods of football contact position and device
Technical field
The present invention relates to the communications field, more particularly to a kind of football contact position recognition methods and system.
Background technology
In football match, direct free kick is a kind of mode of team's score.Due to except the dynamics of playing football controls it
Outside, the skyborne running orbit of football causes mainly due to the different contact position of tactile ball pin and football, therefore various
The initial training for playing skill art of anticipating should be touched with assurance based on ball position.
Under prior art, free kick training is to touching the assurance of ball position often through the operation rail that football is observed after playing football
Mark judges, and can not observe moment of playing football and have an effect the contact position of pin and football, so as to cause training effectiveness very low.
The content of the invention
The embodiment of the present invention provides a kind of football contact position recognition methods and device, to help football player or football
Fan observes the contact position of tactile ball pin and football at any time, so as to adjust tactile ball position next time, quickly and efficiently trains
Outstanding free kick footwork.
The embodiment of the present invention provides a kind of football contact position recognition methods, the described method comprises the following steps:Outside football
Surface obtains the pressure of the tactile ball pin application of football player and the correspondence position point inside football is converted into many site electric signals;
Many site electric signals are converted into multidigit space of points co-ordinate position information and are sent to peripheral hardware display eventually by wireless transmission method
End;Peripheral hardware display terminal handles multidigit space of points co-ordinate position information and touches ball pin instep and football outer surface when showing tactile ball
Contact position.
Further, the football outer surface obtains football player and touches pressure and pair inside football that ball pin applies
The step of answering location point to be converted into many site electric signals includes:Electric resistance touch-control panel under face outside football senses tactile
Ball pin puts on the pressure on football surface;Each contact site and change on the pressure dissipation to electric resistance touch-control panel are connecing
Touch electric signal of the resistance formation in site along particular spatial coordinates direction of principal axis.
Further, the step of electric signal is converted into multidigit space of points co-ordinate position information includes:Resistance-type is touched
Each contact on panel is controlled by along processor of the electric signal transmission of each space coordinate direction of principal axis to football center;Processor will be detectd
The electric signal measured calculates spatial coordinate location information.
Further, the peripheral hardware display terminal handles multidigit space of points co-ordinate position information and touches ball when showing tactile ball
The step of pin instep and the contact position of football outer surface, includes:Peripheral hardware display terminal is adjusted according to the space coordinate coordinate received
With hollow toroidal function of function library and rendering space curved surface;Space curved surface described in reference standard spherical function amendment, in standard
It is fitted on football face and shows the contact position information with border.
To achieve these goals, according to another aspect of the present invention, a kind of football contact position identification dress is additionally provided
Put.
According to the contact position identifying device of the present invention, including:Football and peripheral hardware display terminal.
Further, the football includes electric resistance touch-control panel and processor.The electric resistance touch-control panel is by football
Sportsman touches correspondence position point of the pressure of ball pin application inside football and is converted into many site electric signals;The processor will be many
Site electric signal is converted into multidigit space of points co-ordinate position information and is sent to the peripheral hardware by wireless transmission method and shows
Terminal.
Further, the peripheral hardware display terminal includes data processing module and display module.The data processing module
According to space coordinate coordinate call function hollow of the storehouse toroidal function and rendering space curved surface received.The display module shows
Show that kicker touches ball pin instep and the contact position on football surface.
By the present invention, what kicker can be more efficient trains the free kick footwork and high-altitude pass footwork of maturation, is
Kicker increases technical ability.
Brief description of the drawings
In order to illustrate the technical solution of the embodiments of the present invention more clearly, below will be in correlation technique or embodiment description
The required accompanying drawing used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present invention
Example is applied, for those skilled in the art, other accompanying drawings can also be obtained such as these accompanying drawings.
Fig. 1 is the flow chart of the football contact position recognition methods of the embodiment of the present invention.
Fig. 2 is the structural representation of the football contact position identifying device of the embodiment of the present invention.

Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, the every other embodiment that those skilled in the art are obtained, belongs to the scope of protection of the invention.
Fig. 1 is the flow chart of the football contact position recognition methods of the embodiment of the present invention, and as described in Figure 1, this method includes:
Step S101, football outer surface obtains football player and touches pressure and the corresponding position inside football that ball pin applies
Put and be a little converted into many site electric signals.
In one embodiment of the invention, near kicker's run-up to football exhaust position, a pin stops movement, separately
One pin is rocked to football ad-hoc location and puts on football surface with first kinetic energy, and football surface is under pressure and occurs concave change
Shape.Now, located at going the electric resistance touch-control panel of football surface once to sense the pressure that tactile ball pin puts on football surface;And
And by each contact site on pressure dissipation to electric resistance touch-control panel, the resistance on the contact site changes and formed
Along the electric signal of particular spatial coordinates direction of principal axis.
Step S102, many site electric signals are converted into multidigit space of points co-ordinate position information and by the side of being wirelessly transferred
Formula is sent to peripheral hardware display terminal.
In one embodiment of the invention, electric signal of each contact site by the position along each space coordinate direction of principal axis is passed
It is defeated by the processor at football center;The electric signal detected is calculated spatial coordinate location information by processor according to preset function
And give peripheral hardware display terminal by wireless transmission.Described wireless transmission method includes:Bluetooth, WLAN,
Mobile communication technology.
Step S103, peripheral hardware display terminal handles multidigit space of points co-ordinate position information and touches ball pin pin when showing tactile ball
