Abstract

The invention discloses an automatic detection method for corn tassel traits. The method firstly performs target detection on the collected field corn bottom view images, generates tassel candidate frames to obtain tassel potential areas, and then uses multi-view image features And the Fisher vector encoding method is used to describe the characteristics of the tassel and detect the target, so as to confirm the area to which the tassel belongs. At the same time, on the basis of the detection results, the semantic segmentation is used to further complete the segmentation of the fine shape of the tassel, and finally the image feature is established. The mapping relationship between the length trait, the width trait, the girth trait, the diameter trait, the ear color trait, the branch number trait and the total ear number trait, which has seven physical meanings. The method of the invention can continuously monitor the growth state of corn tassels in real time, has high accuracy of detection results, and has important significance for research on reproductive growth of corn, research on corn genetics and genetics, and yield estimation.

Description

technical field

[0001] The invention belongs to the cross field of computer vision and agricultural meteorological observation, and more specifically relates to an automatic detection method for corn tassel traits, that is, the traits of corn tassels in the image are obtained by taking the field corn bottom-view image sequence as the object feature method. Background technique

[0002] As one of the three major food crops in the world, corn is widely planted all over my country. Analysis and research on various traits of corn can help to establish the relationship between its traits and yield to obtain greater benefits, and can also provide a basis for the study of corn genetics and genetics. However, for a long time, the detection of various traits of maize has been mainly through manual detection, which is easily affected by subjective factors and inefficient; at the same time, the observation process will inevitably cause damage to the growth environment of maize; and be...
