摘  要：
以Matlab为开发平台,提出了一种对甘蔗茎节识别的方法。通过灰度处理和Sobel边缘提取对甘蔗节进行预处理,再结合数学形态学中的膨胀、腐蚀再膨胀对预处理后的不连续、细小边缘进行处理,消除甘蔗茎边缘及无用小边缘,获得甘蔗节的边缘直线。通过Radon函数进行直线提取,得出甘蔗节在R取得最大值时的位置坐标,为甘蔗种茎切割防伤芽装置的控制研究提供准确信息。试验表明甘蔗节识别率达100%,其位置精确到0.1 mm级。

摘  要：
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.
