The purpose of this study is to develop a crop-row detector which can be applied to an automatic guidance system for cultivators or thinning machines. In this paper, a possibilty of practical use of new crop-row detecting method was discussed based on computer simulation. This detecting method consists of two principal means. One is the hardware means to convert the two-dimensional crop-row vision to the compacted one-dimensional information. The locations of two different points on the target row are detected by this means. This is an effective technique for a real time detecting. Another is the software means to estimate the offset value and the heading angle between the detector and the target crop-row which can be assumed as a linear line. As a result of discussion, the detectable limits and its conditions were clarified, and it was concluded that this detecting method would be accurate enough for practical use.
