Abstract

In a project which has lasted 3 years, a vision guidance system has been developed to the stage where commercial viability is imminent. Six prototypes have been field tested by farmers and two more are on trial in the United States. There have been several changes of technology
but the fundamental principles have remained consistent. The system derives its guidance signal from a video camera image of the rows of a crop such as cotton. It is relatively insensitive to additional visual 'noise' from weeds, while tolerating the fading out of one or more rows
in a barren patch of the field. The software integrates data from several crop rows, and tests each row for image
quality. Colour components of the image signal can be selected to improve discrimination between crop and detritus. Experimental results are presented showing that the system is capable of maintaining an accuracy of 2cm. Some farmer responses from the extensive field trials are also included.
