| 摘 要： | 开发了基于机器视觉和模糊控制原理的精确农药可变量喷雾控制系统，并在实验室进行了试验研究。研究表明，系统能融合树冠面积信息和距离信息，通过模糊决策来判断树木大小和距离，进而选择不同的喷头组合，并控制喷雾系统的流量和喷头射程，实现对树木目标的智能喷雾，从而大幅减少农药用量。

| Abstract: | A machine vision and fuzzy control based spray system, which could perform site-specific pesticide application, was developed and tested for the study on Variable Rate Technology(VRT). The system could integrate information of the tree canopy with the distance between the tree and the nozzles to judge the tree size, and then to select different nozzle groups, as well as to control the flow rate and spraying range. In this way, an intelligent chemical delivery was achieved. Compared with traditional methods, the system could greatly save pesticide. |
