A method for detecting cutting width, cutting height, and crop density in a rice-wheat combine harvester is proposed. This method utilizes a trained semantic segmentation model, UANet, to obtain unharvested areas. The world coordinates of pixels in the unharvested areas are obtained through coordinate transformation between pixel coordinates and the world coordinate system. The actual cutting width is then calculated, and the plant height data for the selected plant height measurement area is obtained. After random downsampling and K-means clustering of the plant height data, the maximum average value within the maximum value interval is calculated as the actual plant height. Combined with the header height, the actual cutting height is obtained. By inputting rice and wheat ear images and density detection boxes into a trained improved YOLOv5 model, the density of rice and wheat ears can be obtained from the number of ears in the density detection boxes. Ultimately, this method ensures the accuracy of cutting width, cutting height, and crop density detection.
