摘要
基于最短距离法的原则,设计了一种时间匹配算法用来监测喷雾装备前进的速度。首先,在运动路径中设置匹配点;然后,利用GPS接收机静态采集的匹配点位置信息匹配GPS接收机动态采集的轨迹信息,从而可以得到装有GPS接收机的运动装置在运动过程中经过匹配点的时间;最后,通过实验使用GPS接收机和机器人来修正这一匹配算法,提高了匹配精度。
A kind of arithmetic was designed based on the method of the shortest distance between two points to supervise velocity of spray equipment, Firstly matching points were set on the route. Then the positioning data of the matching points that the GPS receiver received statically was used to match the route data that the GPS receiver collected dynamically, therefore the time when the motion equipment equipped with GPS receiver exactly passed over the matching points was got. Finally through experiment and with the use of GPS receiver and robot this matching arithmetic was rectified and th~ matching accuracy was enhanced.
