    • A system and method of identifying a position of a crop row in a field, where an image of two or more crop rows is transmitted to a vision data processor. A preferential scan line profile in a search space about a candidate scan line profile is determined, and the candidate scan line profile is identified as a preferential scan line profile for estimating a position (e.g., peak variation) of one or more crop rows if a variation in the intensity level of the candidate scan line profile exceeds a threshold variation value. Alternatively, a position datum associated with a highest intensity value within the array of vector quantities can be selected as being indicative of a candidate position of a crop row. The candidate position is then identified as a preliminary row position if a variation in intensity level of the candidate scan line profile exceeds a threshold variation value.
    • 一种识别场中裁剪行的位置的系统和方法,其中两个或多个裁剪行的图像被发送到视觉数据处理器。 确定关于候选扫描线轮廓的搜索空间中的优选扫描线轮廓,并且将候选扫描线轮廓识别为用于估计一个或多个裁剪行的位置(例如,峰值变化)的优选扫描线轮廓,如果 候选扫描线轮廓的强度级别的变化超过阈值变化值。 或者,可以选择与向量量阵列内的最高强度值相关联的位置数据,以指示作物行的候选位置。 如果候选扫描线轮廓的强度级别的变化超过阈值变化值,则将候选位置识别为初步行位置。
