摘要
根据水稻叶片的三维形态特征,应用Bezier曲线描述水稻叶片的边缘信息和一元二次曲线方程描述叶脉曲线,构建一种符合生物学规律的水稻叶片弯曲三维模型,并通过对叶片边缘点绕叶脉的旋转构建了叶片的扭曲模型,较真实地反应了自然条件下水稻叶片的三维空间形态。
Bezier curve is presented to describe the rice leaf edge information and one yuan conic description of the rice leaf vein curve according to the leaf blade morphology 3 D. Bending model of rice leaf blade with the biology is constructed and twisting model of leaf blade is built by rotated the coordinates of leaf blade edge. True to the ground under natural conditions of the three - dimensional space of rice leaf morphology.
