为研制适于南方水田小面积作业的小型农机定位系统,设计了一套用于农田激光三点定位系统的激光接收器。激光接收器通过靶标随动机构实时调整接收靶的回转角度,确保其有效接收激光发射源发射的信号;为准确识别靶标上的激光光斑中心,建立了基于算术平均值滤波算法、中值滤波算法和α–β滤波算法的激光光斑预处理算法。将激光接收器安装在插秧机上进行激光接收动态试验,结果表明,当插秧机在距离激光发射器约100 m处以5、12、20 cm/s速度运动时,激光接收器均能准确接收激光发射器发射的激光信号,并识别着靶信息,实时反映出插秧机的运动状态。

To develop a small agricultural machine location system for small paddy fields in the south of China, we have designed a laser receiver for farmland laser ＆ three point location system. The laser receiver adjusts its receiving target rotation angle in real time through the servo mechanism, to ensure that it can effectively receive the signal transmitted from the laser emission source. Meanwhile, in order to accurately identify the laser spot center of the target, we have studied, the laser spot preprocessing algorithms based on the arithmetic ...
