机器视觉喷药机器人的研发

Design of spraying robot based on machine vision

为解决温室内农药喷洒的浪费现象,减少土壤中的农药残留问题,开发基于机器视觉的喷药机器人。该系统通过TMS320DM642对温室内作物和杂草进行识别,将处理结果上传至ARM处理器并控制喷药机械手进行喷药。该机器人能正确辨别特定的作物和杂草,并根据作物和杂草面积大小和分布状况进行对靶变种类喷药,即:对杂草喷洒除草剂,对作物喷洒除虫剂。同时,该系统还加入了Zigbee无线通讯和视频传输模块,实现了喷药的无人化和智能化。

It was designed in order to reduce the waste in pesticide spraying and the pesticide residue in soils. The system could identify the crops and weeds in greenhouse by the TMS320DM642 and uploaded the results to the ARM processor so that the ARM processor could spray through controlling the spraying manipulator. Moreover, this robot could identify the specific crops and weeds in perspective, and aim target and spray in variable types ac- cording to the area and distribution status of the crops and weeds. Namely, it sprays insecticide on crops and sprays herbicide on weeds. Meanwhile, the system joined the Zigbee wireless communication and video transmission modules so that it could realize unmanned and intelligent spraying.
