Embodiment Construction

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] The animation of flower opening based on physical simulation cannot truly reflect the actual flowering process; and the existing 4D reconstruction methods cannot be directly used to reconstruct the flower opening process due to the complex geometric characteristics of flowers and serious self-occlusion. The reconstruction of the flower opening process can be regarded as the tracking problem of multiple objects under mutual occlusion. This is...

Abstract

The invention discloses a flower opening process reconstruction method and a flower opening process reconstruction device. The method comprises the following steps: collecting four-dimensional point cloud data in the whole flower opening process; selecting a frame of point cloud data comprising all petal information, and creating a flower grid template according to the point cloud data, wherein the flower grid template comprises a plurality of petal grid templates; driving the flower grid template performing grid deformation so as to track the point cloud data based on a corresponding relationship between the flower grid template and the point cloud data, respectively obtaining the flower grid template corresponding to each frame of the point cloud data, and performing shape constraint, collision constraint and fixed root constraint on each petal grid template in the grid deformation process; arranging all the obtained flower grid templates according to a flower opening sequence, namely obtaining the dynamic flower opening process. According to the invention, efficient deformation of the flower grid templates is performed in a data drive manner on the basis of the collected real point cloud data and the created flower grid templates, and the accurate and vivid flower opening process can be reconstructed.

Description

technical field [0001] The invention relates to the technical field of simulation modeling, in particular to a reconstruction method and device for a flower opening process. Background technique [0002] In the field of biological sciences, the study of flower opening process has a long history. Traditionally, such studies have relied on manually documenting the process, or taking pictures at intervals with a camera, and taking measurements on the pictures. Such a workflow is cumbersome and inefficient, prone to measurement bias. [0003] Advances in three-dimensional (3D) scanning technology offer new opportunities and methods to precisely measure the flower opening process. 3D scanning is mainly used to scan the spatial shape, structure and color of the object to obtain the spatial coordinates of the object surface. The significance of 3D scanning is that it can convert the three-dimensional information of the object into a digital signal that can be directly processed ...
