Plant palmate leaf multiscale modeling method

Abstract

The present invention relates to a plant palmate leaf multiscale modeling method and a device. The method comprises a step of obtaining the multiscale leaf characteristic of a palmate leaf, a step of extracting the structured characteristic points of the multiscale leaf characteristic from the point cloud geometry model of the palmate leaf so as to obtain the leaf edge characteristic line, the fold characteristic line, and first, second and third stages of leaf vein characteristic line of the palmate leaf, a step of carrying out dispersion of the above characteristic lines, a step of constructing the parameter curved surface of the palmate leaf with the leaf edge characteristic line as a boundary, a step of obtaining the structure characteristic line sample point set and parameter curved surface sample point set of different grid scales in the parameter curved surface according to different sample parameters, a step of connecting the structure characteristic line sample point and parameter curved surface sample point corresponding to each size to form a constraint line, and a step of obtaining the grid model of the palmate leaf on the basis of the above constraint line. The device is realized based on the above method. According to the method and the device, the multiscale palmate leaf grid model can be constructed while a leaf vein characteristic is ensured, and the efficiency is improved through reducing a grid quantity.

Description

technical field [0001] The invention relates to the technical field of computer graphics, in particular to a multi-scale modeling method for plant palm leaves. Background technique [0002] Agriculture is the foundation of China's national economy. Agricultural informatization is an important symbol of agricultural development in this century and an important part of agricultural modernization. In the process of implementing agricultural informatization, agriculture can obtain multiplied benefits through informatization. The information industry can form an agricultural information industry through information software and hardware services for agriculture, and finally form a win-win situation for agriculture and information industry. Modern agriculture is inseparable from information services in all aspects of agricultural production and circulation. Agricultural information has already involved all aspects of agricultural production and circulation. In addition to the sy...
