发布时间：2019-02-26 12:14
【摘要】：近年来,随着多点触摸发展的日益多元化,触摸屏的结构日趋复杂,触摸算法日渐新颖。提出了一种触摸坐标点计算的新方法,将其称为"投壶"算法,意为将满足条件的物体准确投入壶中,此时壶里的权重增加,最后将权重最大的壶视为"真实"即为有触摸点的。实验证明,此算法能够在硬件资源有限的条件下,准确的计算触摸点的坐标,尤其在多点触摸的情况下,能够有效的避免伪触摸点的出现,具备一定的抗干扰能力,具有响应速度快、计算精度高等特点,实现触摸屏的无驱安装。
[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.
