2. The touch detection method according to claim 1, wherein when the mobile terminal detects that the finger touches the touch screen, starting a timer, further comprising:
the mobile terminal presets the overtime of the timer as preset time.
3. The method for detecting a touch according to claim 1, wherein if the touch center point is unchanged, closing the timer and reporting the touch center point coordinates, specifically comprising:
if the mobile terminal judges that the horizontal coordinate average value f1 and the vertical coordinate average value f2 are not changed, the coordinates of the touch center point are not changed;
and the mobile terminal closes the timer and reports the coordinates of the touch center point.
4. The touch detection method of claim 2, wherein the preset time is 2 seconds.
5. A touch detection system, the touch detection system comprising:
the touch detection module is used for starting a timer when detecting that the finger touches the touch screen;
the touch processing module is used for detecting whether the touch center point of the touch screen changes or not, if the touch center point does not change, closing the timer and reporting the coordinates of the touch center point;
if the mobile terminal detects that the touch center point changes, repeatedly detecting whether the touch center point of the touch screen changes or not until the timer is overtime;
the touch processing module specifically comprises:
the mobile terminal comprises a central point coordinate detection unit, a touch screen and a touch screen, wherein the central point coordinate detection unit is used for acquiring the central point coordinate detected by the current touch screen by the mobile terminal;
the coordinate value acquisition unit is used for acquiring all coordinate points detected by the current touch screen by the mobile terminal, and acquiring an abscissa maximum value, an abscissa minimum value, an ordinate maximum value and an ordinate minimum value from all coordinate points;
a coordinate average value calculation unit, configured to calculate an abscissa average value f1 according to the abscissa maximum value and the abscissa minimum value, and an ordinate average value f2 according to the ordinate maximum value and the ordinate minimum value;
the coordinate change judging unit is used for judging whether the abscissa average value f1 and the ordinate average value f2 are changed or not;
the duplicate detection module includes:
the second touch center point coordinate judging unit is used for judging that if the mobile terminal judges that the horizontal coordinate average value f1 and the vertical coordinate average value f2 are changed, the touch center point coordinate is changed;
the repeated judging unit is used for repeatedly detecting whether the touch center point of the touch screen changes or not by the mobile terminal until the timer is overtime;
when the mobile terminal inputs through the touch screen, the central point position of the touch input is accurately detected, and the correct application program is opened through the central point position, so that the influence of incorrect operation input caused by low operation speed or uneven finger surface is effectively reduced.
6. A mobile terminal, the mobile terminal comprising: a memory, a processor and a touch detection program stored on the memory and executable on the processor, which when executed by the processor, implements the steps of the touch detection method of any of claims 1-4.
7. A computer readable storage medium storing a touch detection program which when executed by a processor implements the steps of the touch detection method according to any one of claims 1-4.
