In a grain sampling and imaging device, a grain bin () is located under a sampling body (), a grain feed connector () is fixed to a top of the sampling body (), an observation window () is installed on the sampling body (), a camera () is installed above the observation window (); grains fall to a grain feed connector (), and then into the sampling body (), and then are sieved by multiple passages of the sampling body (), a part of the grains randomly enter the observation window () and photographed by the camera (), and finally all of the grains enter the grain bin () through a discharge outlet () provided at a bottom of the sampling body ().

Grain sampling and imaging device

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.
