摘　　要：应用计算机图像分析技术 ,拍摄和分析了甘蔗剥叶刷式剥叶机构剥叶的全过程 .提取和分析了钢丝图像上下端点的坐标值、端点之间的直线距离、钢丝的总长度和钢丝图像的转角位置等特征参数 .绘制了钢丝上端点坐标X值、Y值以及钢丝弯曲程度与钢丝的转角位置之间的关系曲线 .发现甘蔗的剥叶过程由 3个阶段组成 :接触压紧阶段。On the basis of pilot experiments, computer image technology was applied to investigate the whole process of sugarcane detrashing. The parameters of the image of a steel wire, including coordinate values of the top and bottom ends of the wire, the straight distance between two ends, the total length and turning angle of the wire were studied. The relationship curves between turning angles and the X value, Y value of the up end of the wire, and degree of bending of the wire were drawn. It was found that the process of the sugarcane detrashing could be divided into three phases: touching and compressing, bending and deforming, sliding and detrashing.
