Detailed Description
Example one
The embodiment of the invention provides a pen-type drawn line counting method, which is shown in a figure 1 and a figure 2 and comprises the following steps:
(1) setting a time idle threshold value of a valid counting signal;
(2) detecting a counting trigger signal triggered by the acquisition pen core in real time;
(3) extracting the idle time period of the non-trigger signal at the rear end of the counting trigger signal in real time and comparing the idle time period with the preset time idle threshold of the effective counting signal;
(4) in the trigger signal queue, signals meeting the condition that the idle time period of a non-trigger signal at the rear end of the counting trigger signal is greater than or equal to the time idle threshold of a preset effective counting signal are effective trigger signals, data statistics is counted, and all other trigger signals which do not meet the condition are ignored.
In embodiment one, we mark the time idle threshold of the active count signal as T; the time idle threshold T of the effective counting signal is obtained by statistics according to the time interval characteristics between adjacent different operation action strings, and needs to be counted, selected and set in advance before counting operation; the action string is a combination of one or more actions operated by completely drawing the same marker, one operation action triggers one counting signal, and correspondingly, the action string triggers one or more counting signals; the time idle threshold T of the valid count signal is set according to the following principle: the time interval between adjacent single actions in any operation action string is less than the time idle threshold value T of the effective counting signal and less than or equal to the minimum value of the time interval between any two adjacent different operation action strings; as in fig. 2, the t1, t2, t4, t5, t6, t7, t9, t11, t12, t13, t14, t15, t16, t18, t19 time periods are time intervals between adjacent individual actions in the operational action string; any one of the values of time interval between adjacent individual actions in the action string < time idle threshold T of the active count signal, T1, T2, T4, T5, T6, T7, T9, T11, T12, T13, T14, T15, T16, T18, T19 is less than the time idle threshold T of the active count signal, where T2 is the largest, so the time idle threshold T of the active count signal > T2; d1, D2, D3, D4 and D5 are operation action strings respectively; t3, t8, t10 and t17 are the intermediate intervals of the operation action strings D1, D2, D3, D4 and D5 respectively; according to the fact that the time idle threshold T of the effective counting signal is smaller than or equal to the minimum value of the time interval between any two adjacent different operation action strings, at the moment, the minimum value of T3, T8, T10 and T17 is taken, here, T3 is smaller than T8, T10 and T17, so that T3 is selected as a threshold value reference, and the time idle threshold T of the effective counting signal is set to be smaller than or equal to T3; in sum, T2 is less than the time idle threshold T of the effective counting signal and less than or equal to T3, and T is within the range to select a value.
In the first embodiment, the counting trigger signal is an electric signal generated when the pen core triggers the counting switch during the drawing action of the pen point; as shown in fig. 2, the arranged black dots S are all represented as count trigger signals, but not all are valid signals at this time, and subsequent comparison determination is required.
In the first embodiment, all the counting trigger signals trigger the contrast program correspondingly; the comparative procedure was: comparing the idle time period of the non-trigger signal at the rear end of the counting trigger signal with the time idle threshold T of the effective counting signal; as shown in fig. 2, when the time occurrence of T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, T11, T12, T13, T14, T15, T16, T17, T18, T19 and T20 is in real time, the time occurrence is respectively compared with the time idle threshold T of the valid count signal.
In the first embodiment, when the idle time period of the no-trigger signal at the rear end of the counting trigger signal is less than the preset time idle threshold T of the effective counting signal, the counting trigger signal is ignored and is not counted; when the idle time period of the non-trigger signal at the rear end of the counting trigger signal is not less than the preset time idle threshold of the effective counting signal, the signal is regarded as an effective signal and is counted; as shown in figure 2 of the drawings, in which,
t1, T2, T4, T5, T6, T7, T9, T11, T12, T13, T14, T15, T16, T18 and T19 are respectively compared with the time idle threshold value T of the effective counting signal and are all smaller than the time idle threshold value T of the effective counting signal, so the trigger signals before the time periods of T1, T2, T4, T5, T6, T7, T9, T11, T12, T13, T14, T15, T16, T18 and T19 are ignored; t3, T8, T10, T17 and T20 are respectively compared with the time idle threshold value T of the effective counting signal, and T3, T8, T10, T17 and T20 are respectively larger than or equal to the time idle threshold value T of the effective counting signal, so that the trigger signals s1, s2, s3, s4 and s5 before the time periods of T3, T8, T10, T17 and T20 are taken as effective signals and counted; s1, s2, s3, s4 and s5 are effective signals, so that the number of effective signals is 5 here, and the display screen displays 5; while other signals are ignored, the count trigger signal that is ignored has no fixed number, and therefore the number of small intervals that are ignored ahead of the valid signal is also indeterminate, as t1, t2, t4, t5, t6, t7, t9, t11, t12, t13, t14, t15, t16, t18, t 19.
