摘  要：
为改进现有智能烟草打顶机数据传输和烟草打顶高度精准识别不足等问题,增强检测算法的实用性和鲁棒性,设计了烟草打顶抑芽机无线控制系统。首先利用无线路由系统进行图像采集;然后采用MSRCR算法对图像进行预处理,消除光照对烟草高度识别的影响;再通过同心圆摄像机标定算法对烟花进行定位,确定打顶高度;最后通过单片机控制步进电动机和电磁阀分别进行打顶作业和抑芽剂的喷施。试验结果表明:该高度检测算法在静态试验下烟花识别率达到98.5%,摄像机标定精确度达96%,打顶准确率达95%。打顶准确率高,抑芽剂喷施精准,系统运行稳定可靠,满足烟草打顶的农艺要求。

摘  要：
Tobacco topping operation was an important link during tobacco planting process. In order to solve the existing problems such as data transmission problem and tobacco topping height recognition problem of intelligent tobacco topping machine,and enhance the practicability and robustness of detection algorithm,a wireless control system for tobacco topping machine was designed. The system could control tobacco topping operation of two rows at the same time,meanwhile complete the integrated operation of tobacco flower identification,tobacco flower location,tobacco topping and sprout inhibitor spraying. The system working principle was as follows: firstly,wireless routing system was used for image acquisition on the machine. Then MSRCR algorithm was used to preprocess the image, so as to eliminate the illumination effect on the tobacco height identification. Then locating the tobacco flower area in the image by a concentric circle camera calibration algorithm and determining the tobacco topping height. Finally,through the control of single-chip microcomputer,stepping motor and pump were used to complete the tobacco topping operation and sprout inhibitor spraying operation,respectively. The test result showed that the tobacco flower recognition rate of the height detection algorithm under the static test can reach 98. 5%; camera calibration accuracy reach around 96%,topping accuracy can reach 95%. The tobacco topping machine had a high topping accuracy rate,precise sprout inhibition,and high system stability,which met the agronomic requirement of tobacco topping.
