摘　　要：本文简要介绍了红外触摸屏技术的优势、实现原理以及在多点识别领域大规模应用亟需解决的问题,并对重点问题"轨迹跟踪"和"抗锯齿"作了说明,指出该问题的由来以及目前算法的缺陷和不足。为解决该问题,本文提出了一种基于目标跟踪的数据关联算法,该算法利用卡尔曼滤波预测下一个触摸点状态,在预测点建立跟踪门,并进行数据关联。最后本文对该算法进行了MATLAB模拟仿真,并进行了实际工程对比。通过前后效果的对比,证明该方案在多点触摸识别领域具有很好的触摸效果。This paper briefly introduces the advantages and implementation principle of infrared touch screen technology, as well as the problems to be solved in the large-scale application in the field of multipoint recognition. The key problems "trajectory tracking" and "anti aliasing" are explained, and the origin of the problem and the defects and shortcomings of the current algorithm are pointed out. In order to solve this problem, a data association algorithm based on target tracking is proposed. The algorithm uses Kalman filter to predict the state of the next touch point, establishes a tracking gate at the prediction point, and carries out data association. In this paper, the algorithm is simulated with MATLAB and compared with the actual project. Through the comparison of the front and rear effects, it is proved that the scheme has a good touch effect in the field of multi touch recognition.
