基于红外超声的九点校准的进化算法

Evolutionary Algorithm of Nine Points Calibration Based on Ultrasonic Infrared

现有交互式电子白板的坐标值往往不具备可移植性和灵活性,因此各项参数会随着时间的增长而发生变化,从而造成定位精度不够高。提出一种基于红外超声的九点校准进化算法,该算法对左右两边接收器获取到的数据进行去抖处理,计算出两边接收器的探头坐标,然后利用其中一个探头坐标建立映射坐标系,最后通过函数拟合进行小范围的精准微调,从而提高定位精度。经实验验证,基于红外超声的九点校准进化算法能够有效避免定位参数随着时间的变化而带来的误差。

Coordinate values of existing interactive electronic whiteboard often lack portability and flexibility.Therefore,the parameter varies with time and locating definition won't be high enough.Thus,a revolutionary algorithm of nine points calibration based on ultrasonic infrared was proposed.This kind of algorithm can deal with the fluctuant data received by the receivers on both sides,work out the coordinate values of the probes on the two receivers,set up the coordinate system using one of the coordinate values and make small-range accuracy adjustment through functional fitting so that the location will be more accurate.According to the experiment,the evolutionary algorithm of nine points calibration based on ultrasonic infrared is able to reduce errors efficiently when the locating parameter changes with time.
