本发明的附加方面和优点将在下面的描述中部分给出，部分将从下面的描述中变得明显，或通过本发明的实践了解到。

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请参阅图1，本发明一实施例提出的触控笔笔迹的优化方法，至少包括以下步骤：
S101，依次读取触控笔的压感数据，将获取到的多个所述压感数据形成压感数据组；
其中，触控笔是用来输入指令到电脑屏幕、移动设备、绘图板等具有触摸屏的终端设备，用户可以通过触控笔点击终端设备的触控屏来选取文件或绘画，触控笔接触触摸屏时会产生由一系列的压感数据组成的压感数据组，该压感数据组是从触控笔刚接触触摸屏开始至触控笔离开触控屏的过程中产生的，该压感数据组原始为二进制数据，终端设备中的应用软件会存在一条读取该压感数据组的线程，同时可以根据相关协议解析该二进制数据，转化为更容易处理的10进制数据，最终转化为上层需要的数据并发送出去。
S102，扩大所述压感数据组的数据区间，所述数据区间为所述压感数据组中最大压感数据和最小压感数据组成的区间；
其中，数据区间为压感数据组中最大压感数据和最小压感数据组成的区间，例如，一个压感数据组中的压感数据包括0,1,3,13,28,35,39,47,50,36,30,26,22,18,15,1,0，则该压感数据组的数据区间为[0,50]，采用数据拉伸的方法，将原始数据的区间扩大，以达到使数据更加精细的目的，扩大所述压感数据组的数据区间具体为整数倍的扩大该数据区间[0,50]，可以理解的，在扩大该压感数据组的数据区间时，可以根据终端设备的实际处理能力选择扩大的倍数，对于性能好、处理能力强的终端设备，扩大的倍数可以比较高，反之，扩大的倍数 应比较小，例如，可以整体扩大4倍，则扩大后的数据区间为[0,200]，扩大数据区间后的压感数据组中的压感数据变为0,4,12,52,112,140,156,188,200,144,120,104,88,72,60,4,0。
S103，当扩大数据区间后的压感数据组中的连续两次压感数据之间的差值大于所述扩大数据区间后的压感数据组中预设的最大间隔时，在所述连续两次压感数据之间补充新的压感数据。
在S103中，首先针对扩大后的数据区间定义一个最大间隔，该最大间隔的可以根据终端设备的实际处理能力确定，对于性能好、处理能力强的终端设备，该最大间隔的数据值可以比较小，这样优化后的数据会更平滑。然后将扩大数据区间后的压感数据组中的连续两次压感数据的差值与该最大间隔时进行对比，若扩大数据区间后的压感数据组中的连续两次压感数据的差值大于该最大间隔，则通过程序智能补点的方法，在所述连续两次压感数据之间补充新的压感数据。
根据本发明实施例的触控笔笔迹的优化方法，能够从软件角度解决触控笔硬件方面的缺陷和限制，首先通过扩大原始压感数据组的数据区间，当扩大数据区间后的压感数据组中的连续两次压感数据的差值较大时，在该连续两次压感数据直接补充新的压感数据，最终将原始的压感数据组中的压感数据变的更加平滑，上层应用在接收到优化后的压感数据后，笔迹变化不再突兀，从而实现更好的书写效果。
请参阅图2，本发明另一实施例提出的触控笔笔迹的优化方法，至少包括以下步骤：
S201，依次读取触控笔的压感数据，将获取到的多个所述压感数据形成压感数据组；
其中，终端设备的应用软件软件中存在一条读取触控笔压感数据的线程，同时根据协议解析该压感数据，该数据来自触控笔硬件，例如依次读取到触控笔发出的压感数据为0,1,3,13,28,35,39,47,50,36,30,26,22,18,15,1,0。
S202，扩大所述压感数据组的数据区间，所述数据区间为所述压感数据组中最大压感数据和最小压感数据组成的区间；
其中，采用数据拉伸的方法，将原始数据的区间扩大，例如，整体扩大4倍，则扩大后的数据区间为[0,200]，扩大数据区间后的压感数据组中的压感数据对应变为0,4,12,52,112,140,156,188,200,144,120,104,88,72,60,4,0。
S203，当扩大数据区间后的压感数据组中的连续两次压感数据之间的差值大于所述扩大数据区间后的压感数据组中预设的最大间隔时，在所述连续两次压感数据之间补充新的压感数据；
其中，首先针对扩大后的数据区间定义一个最大间隔G，例如，定义最大间隔G＝10，然后当扩大数据区间后的压感数据组中的两次压感数据的差值大于10时，在所述两次压感数据之间补充新的压感数据。
请参阅图3，具体在本实施例中，步骤S203包括：
S2031，所述扩大数据区间后的压感数据组中的第一个压感数据直接插入待发送阻塞队列，所述待发送阻塞队列中的数据用于发送给上层应用；
具体实施时，还可以定义一个变量R用于记录上一次的压感数据，再定义一个压感数据待发送阻塞队列Q，队列Q中的数据会发送给上层应用，当接收到第一个压感数据时，赋值给R，同时将值插入队列(该数据会立即被发送给应用)。
S2032，从所述扩大数据区间后的压感数据组中的第二个压感数据起，比较当前的压感数据和上一压感数据的差值与所述最大间隔的大小；
S2033，当所述当前的压感数据和上一压感数据的差值大于所述最大间隔时，在所述当前的压感数据和上一压感数据之间补充数据间隔为A/(A/G+1)、数量为(A/G+1)的新的压感数据，并将所述新的压感数据和当前的压感数据插入所述待发送阻塞队列，其中，A为所述当前的压感数据和上一压感数据的差值，G为所述最大间隔。
具体实施时，接收到第二个压感数据时，比较当前的压感数据和上一压感数据R的差值A与所述最大间隔G的大小；
若A小于或等于所述最大间隔G，则当前的压感数据直接插入所述待发送阻塞队列；
若A大于所述最大间隔G，在所述当前的压感数据和上一压感数据之间补 充数据间隔为A/(A/G+1)、数量为(A/G+1)的新的压感数据，其中，基于计算机的数据处理机制，当A/(A/G+1)或(A/G+1)计算出来结果不是整数时，只取小数点前的整数位。
下面根据本实施例中的具体压感数据给出详细说明：
原始的压感数据为：0,1,3,13,28,35,39,47,50,36,30,26,22,18,15,1,0，数据区间为[1,50]；
扩大后的数据区间为[1,200]，扩大数据区间后的压感数据变为：0,4,12,52,112,140,156,188,200,144,120,104,88,72,60,4,0。
定义最大间隔值G为10，
对于第一个压感数据0，直接插入队列Q；
对于第二个压感数据4，A＝4-0＝4<G，直接插入队列Q；
对于第三个压感数据12，A＝12-4＝8<G，直接插入队列Q；
对于第四个压感数据52，A＝52-12＝40>G则需要补充A/G+1＝40/10+1＝5个点，补充间隔g＝A/(A/G+1)＝8，则补充20,28,36,44,52这几个点.....
以此类推；
最终压感数据变为：
0,4,12,20,28,36,44,52,52,60,68,76,84,92,100,108,112,121,130,139,140,148,156,164,172,180,188,194,200,191,182,173,164,155,146,144,136,128,120,112,104,96,88,80,72,66,60,51,42,33,24,15,6,4,0。
可以看出，压感数据变的更加平滑，根据本实施例的触控笔笔迹的优化方法，能够从软件角度解决触控笔硬件方面的缺陷和限制，首先通过扩大原始压感数据组的数据区间，当扩大数据区间后的压感数据组中的两次压感数据的差值较大时，在该两次压感数据直接补充新的压感数据，最终将原始的压感数据组中的压感数据变的更加平滑，上层应用在接收到优化后的压感数据后，笔迹变化不再突兀，从而实现更好的书写效果。
S204，在补充了新的压感数据的压感数据组中，根据数据相关度对所述补充了新的压感数据的压感数据组中的压感数据进行拟合。
本实施例，还可以对补充了新的压感数据的压感数据组中的压感数据进行进一步优化，根据数据相关度对所述补充了新的压感数据的压感数据组中的压感数据进行拟合，使压感数据的更加平滑。
其中，步骤S204具体包括：
定义初始数据组和相关度权重数组；
将所述补充了新的压感数据的压感数据组中的压感数据依次代入所述初始数据组中，并根据所述相关度权重数组对所述补充了新的压感数据的压感数据组中的压感数据进行平衡，以获得平衡后的压感数据。
具体实施时，首先保存一个长度L的数组(在一次设置一个软件中这个长度应该是固定的)，数组中每个值代表最近的L个元素的相关度，比如数组长度L为5，代表和当前数值和最近的五个值相关。可以根据机器的性能和需求，调整数组长度和相关度权重。具体在本实施例中，相关度总数为2的n次方，例如，相关度总数为2的5次方，即相关度总数为32，各个值相关度为2,4,7,7,12。首先保存一个压感数据队列，队列的每一个新值都是根据5个值乘以各自权重，在进行右移n位生成，在用这样的数据进行书写笔迹会很流畅自然。
下面通过一具体数据组进行详细说明：
接收到的触控笔的压感数据为：
0,4,12,19,26,33,40,47,52,60,74,76,84,92,100；其中，第11位的压感数据74为突变数据。
定义初始数据数组为[0,0,0,0,0]，定义权重数组为[2,4,7,7,12]；
将第1个压感数据0代入初始数据数组中，得数据数组[0,0,0,0,]，平衡后的压感数据为(0*0)/2＝0；
将第2个压感数据4代入数据数组中，得数据数组[0,4,0,0,0]，平衡后的压感数据为(0*2+4*4)/6＝2；
将第3个压感数据12代入数据数组中，得数据数组[0,4,12,0,0]，平衡后的压感数据为(0*2+4*4+12*7)/(2+4+7)＝7；
将第4个压感数据19代入数据数组中，得数据数组[0,4,12,19,0]，平衡后的压感数据为(0*2+4*4+12*7+19*7)/(2+4+7+7)＝11；
将第5个压感数据26代入数据数组中，得数据数组[0,4,12,19,26]，平衡后的压感数据为(0*2+4*4+12*7+19*7+26*12)/32＝17；
将第6个压感数据33代入数据数组中，得数据数组[4,12,19,26,33]，平衡后的压感数据为(4*2+12*4+19*7+26*7+33*12)/32＝23；
将第7个压感数据40代入数据数组中，得数据数组[12,19,26,33,40]，平衡后的压感数据为(12*2+19*4+26*7+33*7+40*12)/32＝31；
将第8个压感数据47代入数据数组中，得数据数组[19,26,33,40,47]，平衡后的压感数据为(19*2+26*4+33*7+40*7+47*12)/32＝38；
将第9个压感数据52代入数据数组中，得数据数组[26,33,40,47,52]，平衡后的压感数据为(26*2+33*4+40*7+47*7+52*12)/32＝44；
将第10个压感数据60代入数据数组中，得数据数组[33,40,47,52,60]，平衡后的压感数据为(33*2+40*4+47*7+52*7+60*12)/32＝51；
将第11个压感数据74代入数据数组中，得数据数组[40,47,52,60,74]，平衡后的压感数据为(40*2+47*4+52*7+60*7+74*12)/32＝60；
将第12个压感数据76代入数据数组中，得数据数组[47,52,60,74,76]，平衡后的压感数据为(47*2+52*4+60*7+74*7+76*12)/32＝67；
将第13个压感数据84代入数据数组中，得数据数组[52,60,74,76,84]，平衡后的压感数据为(52*2+60*4+74*7+76*7+84*12)/32＝75；
将第14个压感数据92代入数据数组中，得数据数组[60,74,76,84,92]，平衡后的压感数据为(60*2+74*4+76*7+84*7+92*12)/32＝82；
将第15个压感数据100代入数据数组中，得数据数组[74,76,84,92,100]，平衡后的压感数据为(74*2+76*4+84*7+92*7+100*12)/32＝90。
最终平衡后的压感数据为：0,2,7,11,17,23,31,38,44,51,60,67,75,82,90，可以看到，第11位的突变数据74为被很好的平衡。最终压感数据得到进一步优化，书写会更加平滑。
可以理解的，由于权重数组为会影响最终的压感数据，因此还可以通过对平衡后的压感数据组的两个压感数据之间做向量，两个向量之间做运算，如果变化过大，可以动态调整权重数组，使最终的压感数据更加接近自然书写的状 态。
