A method to aim toward crop-rows was put forward for spray control in this article. At first, the image of crops captured by a CCD camera was passed on computer, then crops were segmented from background by obtaining H value and its binary image was obtained by means of OSTU. Finally, the center line of crop-row was regressed by Hough transform after the binary image was morphologically eroded. A spray control system was designed to move the spray nozzle accurately on crop row.
