摘      要：Automatic navigation of agricultural machine has been applied in varies *** as a new navigation technology,Vision-Guided system is more flexible and more adaptable comparing with Global Position System(GPS)and Inertial Navigation System(INS).By operating a CMOS camera via USB interface with DirectShow technology,this paper realized an effective and cost-saving image *** more,the Between-Class Variance method,which proposed by Otsu,is improved and be used to automate the gray- scaling and ***,the modules of image capture,processing and navigation planning are programmed into software running on a computer, and the result of the experiment shows that the systems is capable of recognizing roads and planning the path under ideal lighting circumstance.
