摘要
基于线阵CCD技术的交互式电子白板由于其低成本及可高效率地实现多点触控,展现出较大的发展潜力。针对采用线阵CCD技术的电子白板普遍存在的伪触摸点问题,在动态建模基础上分别采用扩展Kalman滤波算法和粒子滤波算法解决触摸点目标跟踪问题。结果表明,与传统的扩展卡尔曼滤波算法相比,粒子滤波算法提高了目标跟踪的精度,更好地解决了伪点问题。该研究结果可为交互式电子白板的设计方法提供理论依据和技术支持。
The interactive white board （IWB） based on linear CCD technique showed great development potential owing to its advantages of low cost, efficient multi-touch. In order to solve the problem of pseudo touch points in CCD technique, the particle filter based on tracking algorithm is adopted. By comparing with the traditional extended kalman filter （EK_F）, the algorithm of particle filter has better performance than traditional EK_F algorithm in tracking accuracy and can solve the problem of pseudo touch points. The result will be used to provide a theoretical basis and technical support for the design of IWB.
