A row detection system includes first and second imaging devices to be mounted on an agricultural machine, and a processor configured or programmed to perform image processing for first and second images which are generated by the first and second imaging devices, respectively. The second imaging device is located so that at least a portion of each front wheel and at least a portion of each rear wheel are included in the second image. The processor is configured or programmed to convert the first image into a first plan view image, convert the second image into a second plan view image, select a region of interest from the first plan view image based on a position of each front wheel and a position of each rear wheel in the second plan view image, and perform a row detection process targeted at the region of interest.

Row detection system and agricultural machine

A crop row detection system includes a camera mounted to an agricultural machine to image a ground surface traveled by the agricultural machine to acquire time-series color images including at least a portion of the ground surface, and a processor configured or programmed to (i) perform image processing for the time-series color images, (ii) generate, from the time-series color images, an enhanced image in which a color of a crop row for detection is enhanced to provide an enhanced image, (iii) generate from the enhanced image a plan view image as viewed from above the ground surface, the plan view image being classified into first pixels having a color index value for the crop row equal to or greater than a threshold and second pixels having the color index value below the threshold, and (iv) determine positions of edge lines of the crop row based on the color index values of the first pixels.
