为提高托盘苗自动分选移栽的自动化程度，减轻劳动强度，设计了一种新型分选移栽机。根据常规育苗托盘的特点和人工分级方法，确定了机械分选程序。分选插秧机的关键部件包括：带气动缓冲的高效传输机构、基于线结构视觉的苗木识别测量单元、可扩展的无线多抓持器和系统控制器。试验结果表明，在6×12孔的托盘上，以每小时700周的速度进行移栽，移栽成功率为90.0%。视觉单元对5个不同托盘上的辣椒优苗的误识率均小于10%，苗高测量误差在5 mm左右。关键词：移栽机、托盘苗木分拣、抓斗、机器视觉、无线技术DOI：10.3965/j.ijab.20150802.1459
In order to improve the automatic sorting and transplanting of tray-seedling and reduce labors strength, a new sorting transplanter was designed. According to the feature of normal seedling tray and manual grading method, the mechanical sorting procedure was defined. The key parts of sorting transplanter are as follows: an efficient transfer mechanism with aerodynamic buffer, a seedling identifying and measuring unit based on linear-structured vision, the extendible multi-grasper with wireless technology and the system controller. The experiments were conducted and showed that the transplanting success rate was 90.0% on the tray of 6×12 holes under the speed of 700 cycles per hour. The vision unit’s failed identifying rate for the superior pepper seedlings on five different trays was less than 10%, and the measurement error of seedling height was about 5 mm.
