Abstract

The invention relates to an image-based plant three-dimensional shape measurement and reconstruction method and a system, and the method comprises the steps of obtaining two images of a target objectin different positions in the vertical direction, obtaining internal parameters of a shooting source, extracting two-dimensional profile information or two-dimensional framework information of the target object from the images, carrying out feature matching on a profile or a framework through the epipolar constraint algorithm, calculating data of a three-dimensional shape structure of the target object according to the internal parameters and the result of the feature matching, and finally obtaining a three-dimensional model of the target object by using spline curves and curved surfaces for fitting and generating the three-dimensional model of the profile or the framework. The method and the system design the corresponding data acquisition method according to the rapid, accurate and non-destructive data acquisition demands of main crops of agriculture by facing to three-dimensional shape acquisition and reconstruction of the main crops, as well as measurement and calculation of main agronomic parameters based thereon, thereby having an important practical significance and broad application prospects for developing practical tools.

Description

technical field

[0001] The present invention relates to the technical field of image-based three-dimensional modeling, in particular to an image-based method and system for three-dimensional shape measurement and reconstruction of plants. 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 involve...
