Abstract
A method and a system for identifying a field boundary are provided. The method includes pre-processing acquired original images to obtain an image data set; training an improved U-Net network to obtain a segmentation model of field regions by taking images in the image data set as inputs, and marked images corresponding to the input images as outputs; wherein the marked images are binary images for distinguishing the field regions from non-field regions, an inverted residual block is set between maximum pooling layers of an encoder of the improved U-Net network, and an inverted residual block is set between deconvolutional layers of a decoder of the improved U-Net network; inputting a current frame image into the segmentation model, outputting a current binary image, and determining a field-side boundary line and a field-end boundary line based on a frame association algorithm and an RANSAC line fitting method.
