Problems solved by technology

[0003] The seed test technology based on a single image only obtains the local information of the ear surface, and the calculation of ear phenotypic traits based on this has the problems of low accuracy and poor stability; the seed test technology based on multiple ear images, although relatively complete acquisition of each However, image splicing and fusion between images is difficult, and the existing system often requires manual operation of a single ear, which seriously limits the efficiency of ear seed testing, and is difficult to meet the needs of large-scale and large-scale ear seed testing. Image-based corn ear seed testing technology is difficult to meet the requirements of high precision and high efficiency of seed test

Abstract

The invention discloses a method and system for corn ear seed test. The method and the system can simultaneously meet the requirements of the corn ear seed test on high accuracy and high efficiency. The method comprises the steps: acquiring images of different side faces of corn ears by using an ear transmission device and a camera, so as to obtain image sequences of the corn ears; splicing the image sequences of the corn ears to form surface panoramas of the corn ears; and determining effective ear grain distribution graphs in the surface panoramas of the corn ears by using an ear grain segmentation and position analysis method, and calculating the phenotypic character index of the corn ears according to the effective ear grain distribution graphs.

Description

technical field [0001] The invention relates to the technical field of corn ear seed testing, in particular to a method and system for corn ear seed testing. Background technique [0002] In order to establish a corn resource bank and carry out corn breeding experiments, corn researchers need to conduct corn ear seed testing (that is, calculate the phenotypic traits of corn ear). At present, it has become a trend to use image processing technology for corn ear seed testing. Compared with manual seed test, it can greatly reduce the cost of test seed and ensure data consistency. [0003] The seed test technology based on a single image only obtains the local information of the ear surface, and the calculation of ear phenotypic traits based on this has the problems of low accuracy and poor stability; the seed test technology based on multiple ear images, although relatively complete acquisition of each However, image splicing and fusion between images is difficult, and the exi...
