Abstract
PURPOSE:To improve sensing accuracy in boundary lines between an unworked region and already worked region, by continuously determining and judging the movement maximum position of frequency distribution from image information sensed on a sensor screen. CONSTITUTION:When a line image sensor advances (a) using a boundary part between an unworked region and already worked region as a visual range, image information on a field in the boundary part is sensed. A boundary point (K) which is the maximum position of frequency distribution is judged from image boundary information (P) on each transverse line every time each transverse line moves by one pitch on one sensor screen (A) as the machine body advances. A boundary line (L) of the continuous boundary points (K) is used as the standard for steering control direction of the working machine to control steering output.
