Patent number: 11676376Abstract: A method for detecting a field navigation line after ridge sealing of crops includes the following steps. A field crop image is acquired. Image color space transformation, image binaryzation, longitudinal integration, neighborhood setting and region integration calculation are sequentially performed on the field crop image to obtain a crop row image. Detections of an initial middle ridge, a left ridge and a right ridge are performed on the crop row image to obtain center lines of the initial middle ridge, left ridge and right ridge. Center lines of a left (right) crop row are established by using an area 1 between the center lines of the left (right) ridge and the initial middle ridge. A center line model of a middle ridge is established by using an area 0 between the center lines of the left and right crop rows, namely a navigation line of a field operation machine.Type: GrantFiled: September 15, 2020Date of Patent: June 13, 2023Assignee: ZHEJIANG UNIVERSITYInventors: Xiuqin Rao, Yangyang Lin, Yanning Zhang, Xiaomin Zhang, Yibin Ying, Haitao Yang, Haiyi Jiang, Yihang Zhu
