Problems solved by technology

[0004] However, due to the complex structure of wheat spikes, the small spacing between plants, the height of overlapping spikes, and the presence of awns in some wheat varieties, it is difficult to accurately identify wheat spike phenotypes. The existing wheat spike recognition methods can only The analysis of the length and width of wheat ears, the projected area and orientation of grains wrapped by glumes can only analyze the parts of wheat ears that are relatively clear and do not overlap, and cannot be applied to the overall study of wheat ears, such as The number of ears of wheat purchased, etc.

Abstract

The invention belongs to the technical field of intelligent biology, and relates to a Faster R-CNN-based wheat ear number identification method and system and a medium, and the method comprises the steps: extracting wheat ear canopy images of different families, carrying out the calibration of wheat ears in the images, and obtaining a label corresponding to each wheat ear; inputting the image and the label of the wheat ear into a ResNet network model for feature extraction to obtain a feature map of the wheat ear, and establishing a corresponding candidate box according to the contour of the wheat ear; the Faster R-CNN model is trained through the feature map, and an optimal wheat ear recognition model is obtained; inputting a to-be-detected wheat ear image into the wheat ear recognition model to obtain candidate frames corresponding to each wheat ear; and counting the number of the candidate frames so as to obtain the number of wheat ears. The molecular marker can be used for carrying out accurate QTL positioning on wheat, can be used for accurately identifying wheat with a high overlapping characteristic of wheat ear number, and is expected to provide a high-throughput analysis tool for wheat molecular breeding seed yield-related phenotype identification.

Description

technical field [0001] The invention relates to a method, system and medium for identifying the number of ears of wheat based on Faster R-CNN, belonging to the field of intelligent biotechnology, and in particular to the technical field of automatic identification of the number of ears of wheat. Background technique [0002] Wheat is an important staple food crop in my country, and its panicle morphological parameters directly reflect the growth status and yield information of wheat (Yang Jinwen et al., 2013), and are important parameters that reflect the quality and yield of wheat. At present, the counting of the number of spikelets and grains in the ear of wheat mainly relies on manual counting, which is not only time-consuming and labor-intensive, but also inefficient. The existing means to solve this problem mainly analyze the plant phenotype by optical imaging, which has obvious advantages over manual counting. Due to the existence of a large number of occlusions, it i...
