Abstract

The invention relates to a method for extracting row lines of rice seedlings, comprising the steps of: obtaining field images of rice seedlings; identifying the field images of rice seedlings through a pre-trained deep convolutional neural network model, and obtaining the coordinates of each seedling in the field images of rice seedlings ; clustering the coordinates of multiple rice shoots, and identifying the current row of rice shoots; performing linear regression on the coordinates of the rice shoots on the current row of job seedlings, to obtain the current row of rice shoots. Through the application of the pre-trained deep convolutional neural network and clustering algorithm, the interference of environmental factors in the rice field can be better eliminated, the current line of seedlings can be identified more accurately, and the automatic driving of the rice transplanter can be guided.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method, device, computer equipment and storage medium for extracting row lines of rice seedlings. Background technique [0002] Agricultural field navigation technology provides navigation information for the operation of modern agricultural production machinery, and has been applied to various agricultural machinery and equipment. The importance of agricultural field navigation is particularly evident in agricultural equipment used for seeding. [0003] At present, the research on agricultural field navigation at home and abroad mainly focuses on machine vision navigation. Meng Qingkuan et al constructed the Cg component that has nothing to do with the light, selected the 2Cg-Cr-Cb feature factor to grayscale the image, established the constraint model of the corn crop line equation according to the characteristics of the crop row in the image, and used the particle swarm opti...
