    摘要:

    以Matlab為開發(fā)平臺,，提出了一種對甘蔗莖節(jié)識別的方法,。通過灰度處理和Sobel邊緣提取對甘蔗節(jié)進行預處理，再結(jié)合數(shù)學形態(tài)學中的膨脹,、腐蝕再膨脹對預處理后的不連續(xù),、細小邊緣進行處理，消除甘蔗莖邊緣及無用小邊緣,，獲得甘蔗節(jié)的邊緣直線,。通過Radon函數(shù)進行直線提取,，得出甘蔗節(jié)在R取得最大值時的位置坐標，為甘蔗種莖切割防傷芽裝置的控制研究提供準確信息,。試驗表明甘蔗節(jié)識別率達100%,，其位置精確到0.1mm級。

    Abstract:

    A method for identifying sugar cane internodes was proposed based on Matlab. The cane internode was pre-processed by using gray processing and Sobel edge extraction. The mathematical morphology of expansion, corrosion and re-expansion was used to eliminate the edge of the sugar cane internode and unwanted small edge, so the edge of sugarcane internodes straight line was obtained. And then, the location coordinates of sugarcane internodes were got when R had its strongest value by using Radon function for straight line extraction. A theoretical basis of device of anti-bud injury in seedcane cutting was provided. The recognition accuracy was 100%, and the position accuracy was 0.1 mm. 
