摘　　要：在规则田块网格识别算法的基础上,阐述了不规则田块的自动网格识别算法。控制器读取传感器的脉冲信号,计算作业机具的行走距离,由不规则田块自动网格识别算法实现机具的自动网格识别。试验结果表明,随着机具的行走,应用该算法可以实现机具在不规则田块不同网格的自动识别,验证了该算法的可行性。The algorithm of automatic grid recognition for irregular fields was introduced based on the algorithm of automatic grid recognition for regular fields.The controller received pulse signals from the sensor and calculated the working distance of the variable rate applicator,thus the working grid could be identified by the algorithm of automatic grid recognition.The field experimental results showed that using this positioning algorithm,the applicator could be automatically recognized in different grid.
