發(fā)布時(shí)間:2019-02-26 12:14
【摘要】:近年來(lái),隨著多點(diǎn)觸摸發(fā)展的日益多元化,觸摸屏的結(jié)構(gòu)日趨復(fù)雜,觸摸算法日漸新穎。提出了一種觸摸坐標(biāo)點(diǎn)計(jì)算的新方法,將其稱為"投壺"算法,意為將滿足條件的物體準(zhǔn)確投入壺中,此時(shí)壺里的權(quán)重增加,最后將權(quán)重最大的壺視為"真實(shí)"即為有觸摸點(diǎn)的。實(shí)驗(yàn)證明,此算法能夠在硬件資源有限的條件下,準(zhǔn)確的計(jì)算觸摸點(diǎn)的坐標(biāo),尤其在多點(diǎn)觸摸的情況下,能夠有效的避免偽觸摸點(diǎn)的出現(xiàn),具備一定的抗干擾能力,具有響應(yīng)速度快、計(jì)算精度高等特點(diǎn),實(shí)現(xiàn)觸摸屏的無(wú)驅(qū)安裝。
[Abstract]:In recent years, with the development of multi-touch, the structure of touch screen is becoming more and more complex, and the algorithm of touch is becoming more and more novel. In this paper, a new method of calculating touch coordinate points is presented, which is called "pitcher" algorithm, which means that the object satisfying the condition can be put into the pot accurately, and the weight of the pot will increase when the weight of the pot is increased. Finally, the most weighted kettle as "true" is a touch point. Experiments show that this algorithm can accurately calculate the coordinates of touch points under the condition of limited hardware resources, especially in the case of multi-touch, can effectively avoid the appearance of pseudo-touch points, and has a certain ability of anti-interference. It has the characteristics of fast response and high calculation precision, and realizes the no-drive installation of touch screen.
