Abstract

The invention provides an on-ridge operation machine navigation path identification method based on field ridge color features, which comprises the following steps: carrying out gray scale reconstruction on a field ridge image by using a brightness information component as a basic information graph based on a gray scale reconstruction method to obtain a gray scale image; extracting pixel values of ridge surfaces and furrows in a grayscale image to obtain a threshold value for segmenting the image, and segmenting the grayscale image in a threshold segmentation mode to obtain a binary image; obtaining a ridge surface convex hull contour point set; and obtaining a center line of a ridge surface quadrangle through a quadrangle approaching method, and taking the center line of the ridge surface quadrangle as a navigation path. According to the invention, the recognition success rate is high, the recognition error is small, and navigation path recognition can be effectively carried out on ridges with different colors and textures.

Description

technical field [0001] The invention relates to the field of intelligent agricultural machinery or the field of technology identification and navigation or image recognition technology, in particular to a method for identifying navigation lines of operating machines on ridges based on the color characteristics of field ridges. Background technique [0002] The working environment of agricultural machinery is harsh, and autonomous navigation operations can reduce manual labor intensity and improve operational efficiency and accuracy. At present, autonomous navigation research mainly focuses on satellite positioning navigation and visual navigation. Transplanters, seeders and other ridge operation machines need to follow the ridge operations without crops. Visual navigation collects and processes field ridge images in real time and extracts navigation paths, which is more in line with the actual requirements of transplanter and seeder operations. [0003] At present, the navi...
