Plant three-dimensional reconstruction method based on image and scanning data

Abstract

The invention discloses a plant three-dimensional reconstruction method based on an image and scanning data. The plant three-dimensional reconstruction method is characterized by comprising the following steps: S100, three-dimensional plant skeleton of the image of a plant is extracted; S200, organ three-dimensional point cloud obtaining, organ characteristic parameter extraction and organ pattern construction are conducted to organs of the plant; and S300, assembling is conducted on the three-dimensional plant skeleton by using a constructed organ pattern according to extracted organ characteristic parameter, and three-dimensional reconstruction is finished. The plant three-dimensional reconstruction method enables the reconstructed three-dimensional mold to be fitted with the height of a practical to-be-constructed plant in the aspects of leaf vein tracing pattern and stalk pattern, and the organs such as leaves and stalk can sufficiently reflect three-dimensional details of the maize variety, and therefore the constructed plant is good in sense of reality, and the method is simple and practical.

Description

technical field [0001] The invention relates to a three-dimensional graphics processing technology, in particular to a plant three-dimensional reconstruction method based on images and scanning data. Background technique [0002] At home and abroad, some work has been carried out on the 3D reconstruction of plants. Typical works can be found at home and abroad as follows: [0003] The first article is "3D Skeleton Reconstruction of Maize Plants Based on Stereo Vision" (Zhao Chunjiang, Yang Liang, Guo Xinyu, etc., 3D Skeleton Reconstruction of Maize Plants Based on Stereo Vision, Journal of Agricultural Mechanics, 2010, 41(4):P157-162 ), the literature extracts two-dimensional skeleton information from two images taken at specific angles, realizes the matching of skeleton features through the epipolar constraint algorithm and sets reasonable matching criteria, obtains three-dimensional skeleton point cloud information, and finally through noise reduction and sampling The thr...
