摘要
搭建了自动对靶自动对靶平台视觉模型,并对各个坐标系之间的坐标转换进行了研究。介绍了自动对靶精准施药平台自动对靶与相机标定,并基于极限学习机实现了自动对靶精准施药决策。实验结果表明:自动对靶精准施药平台准确率达到了77%以上,喷药最大时间为8s,效率较高,具有较高的可行性和有效性,能够满足设计需求。
It firstly built the visual model of automatic target-aligning platform,and studied the coordinate transformation between coordinate systems.Then,it introduced the automatic target-aligning and camera calibration of automatic target-aligning platform.Finally,it realized the decision of automatic target-aligning precision pesticide application based on extreme learning machine.The experimental results show that the accuracy rate of automatic target precise spraying platform is over 77%,the maximum spraying time is 8 s,and the efficiency is high.It shows that the system has strong adaptability to the environment,high feasibility and effectiveness,which can meet the design requirements.
