| 摘 要： | 根据农田作物图像特点,采用基于垂直投影的窗口移动方法,得到代表作物行的定位点,提出了基于机器视觉和随机方法的作物行提取算法.该算法从定位点中随机选取2个不同点,决定一条候选直线,再根据阈值规则,进一步判断候选直线的真实性.实验结果表明,该算法可以提取不同作物的作物行,处理一幅640×480像素的彩色图像平均需要220 ms,正确识别率达98%.

| Abstract: | One way of navigating autonomous vehicles to perform field operations is using a vision of crop rows detection system. A new algorithm for rows recognition was presented based on machine vision and randomized method. During image pre-processing,a vertical projection method was employed to estimate the position of crop rows. Moreover,the randomized method was used for crop rows detecting. A candidate line was determined by two different localization points,which were selected from data space randomly. The th... |
